Abstract: A big problem for farmers is scarcity of resources and the threat to the security of electronic transactions.

Incorporating Post-Quantum Cryptography, this project uses encryption through Kyber and authentication of

signatures through DiLithium, providing security for digital agriculture. It serves as a WordPress security

solution with encrypted data storage, fraud prevention, and secure user authentication. The study also assesses

scalabilit y and performance in quantum-resistant cryptographic techniques. The ability to secure long-term

cybersecurity in agriculture, through the use of these quantum-secure methods, protects interactions between

farmers and advisors, as well as operations within the marketplace, against future threats posed by quantum

computing without compromising on accessibility and operational efficiency.

1 INTRODUCTION

Digital revolution: our project main goal is to be part

of this movement. We aim to launch an integrated

digital platform uniting farmer, and advisors, and

administrators with different digital offerings that

serve these groups (K. Singh, et al., 2019). This is done

through this cutting-edge digital technology, along

with extensive plugins such as WP User Frontend,

WooCommerce, and Amelia, we are designing a

platform that supports performance, efficiency, and

sustainability in agriculture.

Farmers can reduce transaction costs and improve

efficiency through e-commerce features of our

platform to purchase agriculture products and rent

machinery online (R. K. Sharma, et al., 2019). In

addition, farmers can book advisors according to

their location, schedule an appointment and track

progress which allows them to access agricultural

advisory services and experts with more

convenience (A.K. Jain, et al., 2020).

For advisors, our platform offers several tools to

manage their consulting appointments and customer

interactions, and offer farmer consultation and

service (S.K. Singh, et al., 2019). They may also

disseminate educative content, solutions, and best

practices with farmers (K. K. Singh, et al., 2020). Our

platform will improve knowledge-sharing and

collaboration between farmers and advisors to drive

local sustainability and environmental management

in agriculture.

Access to markets and expert advice for farmers

positive impact on livelihoods and income for

farmers and their families. Expose Rethinking

agriculture as a unique and innovative solution to

agricultural problems, we are confident our platform

would have long-lasting benefits on farmers,

advisors, and communities globally.

2 LITERATURE REVIEW

As technology is integrated into farming practices at

an unprecedented pace, digital agriculture is tackling

two of the biggest challenges farmers face. Different

approaches have been presented to enhance

knowledge sharing, advisory, finance, and market

access. But with the growth of digital agriculture, so

too come the cybersecurity threats. Traditional

authentication systems that rely on passwords,

supported by classic encryption techniques such as

AES-256 and RSA, remain vulnerable to brute-force

and quantum computing assaults. Sensitive data from

agriculture, including credentials about farmers,

financial transactions, and advisory records, rely on

digital platforms.

The present study introduces combined PQC

techniques, namely Dilithium digital signatures and

Kyber encryption, to mitigate these cybersecurity

threats. This new cryptography can be used to secure

all aspects of user experience, from designing

password-less authentication processes backed by

quantum-safe digital signatures, eliminating phishing

attacks, credential leaks, and brute-force

compromises. Kyber encryption protects agricultural

data at rest, offering quantum-secure protection and

enabling advisory services and financial payments

to not be compromised. Notably, the adoption of

these PQC methods in WordPress- based agricultural

platforms demonstrates that quantum-resistant

security solutions can be realized without substantial

performance penalties. This study paves the way for

future cyber security developments in agricultural

technology by securing the digital agriculture

platforms with post-quantum cryptography (PQC).

In the past few years, the idea of agricultural

digital platforms has been quite popular. Digital

agriculture can deliver greater productivity, through

improved efficiencies better information and

technology in the right place at the right time and

increased sustainability (Food and Agriculture

Organization of the United Nations, 2019). Likewise,

the International Fund for Agricultural

Development emphasizes the important roles played

by digital platforms in linking farmers to markets,

expanding access to financial services, and

knowledge sharing in agriculture.

Recent studies highlight the ways in which digital

platforms streamline farming practices. Digital

platforms help farmers cut costs and boost yields by

optimizing the farm operation, the Journal of

Agricultural and Applied Economics reports.

Similarly, the International Journal

ofAgricultural Sustainability emphasizes their

importance in the development of sustainable

agriculture and as reducing environmental

degradation.

E-platforms dedicated to agriculture incorporate

e-commerce elements, knowledge-sharing platforms,

and consulting (advisory) services. According to the

Journal of Agricultural Marketing, online

marketplaces provide benefits for agricultural

producers by connecting farmers with buyers,

lowering transaction costs, and generating more

income. On the other hand, emphasize the role of

advisory services to promote significant productivity

and efficiency in the agricultural sector.

But as digital agriculture is growing, the

cybersecurity risks are soaring. Conventional

authentication systems based on passwords and

traditional encryption methods (e.g., AES-256 and

RSA) are susceptible to brute-force and quantum

computer attack. Digital platforms that deal with

sensitive agricultural data, such as farmer

credentials, financial transactions, and advisory

records, need to be equipped with stronger security

mechanisms (R. Kumar, et al., 2021)

To mitigate these cybersecurity threats the study

integrates post-quantum cryptographic (PQC)

algorithms including Di lithium digital signatures

and Kyber encryption. Di lithium eliminates the

need for password-based logins for a user, relying

instead on quantum- safe digital signatures that

render phishing attacks, password leaks, and brute-

force compromises irrelevant (Patel and K. Singh.,

2020). Kyber encryption protects stored agricultural

data using quantum-resistant security, where

advisory services and financial transactions are

uncompromised (S. Johnson., 2020). The

incorporation of these PQC techniques within

WordPress- based agricultural platforms

demonstrates the practicality of quantum-secure

cybersecurity measures without incurring major

performance costs. This research lays the foundation

for future cybersecurity in agricultural technology

by protecting digital agriculture platforms with PQC

(M. Lee, et al., 2021)

3 EXISTING METHODOLOGIES

Traditional Password-Based Authentication:

However, existing web platforms such as WordPress

depend on password authentication mechanisms that

are susceptible to phishing attacks, brute-force

attacks, and credential leaks. Indeed, because these

authentication methods may turn out to be vulnerable

to quantum attacks (Patel and K. Singh., 2020), they

may lose their effectiveness with the technological

evolution of quantum computing.

Implementing Post-Quantum Cryptography

(PQC) in WordPress security: This means building

customized plugins that incorporate Kyber

encryption and Dilithium authentication into current

systems. These plugins improve security for

shopping carts and login systems by using digital

signatures to add secure login mechanisms, protecting

user authentication against potential quantum attacks.

They also provide end-to- end encryption for user

data stored around the web and financial transactions,

which protects sensitive info from getting into the

wrong hands. Moreover, those plugins are meant to

seamlessly interoperate with web apps and to strike a

balance between extensive security and usability as

much as possible, guaranteeing that users are barely

disrupted and still obtain improved protection

because of this (N. Verma and J. Clarke., 2022).

Existing Data Encryption Techniques: Encryption

algorithms (e.g., AES-256, RSA, ECC). AES-256

provides encryption for stored data to preserve its

confidentiality, while RSA and ECC do so for data

in transit, including payments. But they are at a high

risk from emerging cyber threats using newly

developed algorithms such as Shor's and Grover's

algorithms (Patel and K. Singh., 2020), capable of

breaking the current cryptographic systems against

some sort of attacks (T. Nakamoto, et al., 2019). Studies

shows that inorder to protect long-term data security

it is necessary to switch to post-quantum

cryptography (S. Johnson., 2020).

3.1 Challenges in Existing Approaches

Vulnerabilities in Password-Based

Authentication: Standard authentication methods

from the likes of WordPress are vulnerable to

phishing, brute-force train attacks and credential

leaks. Compounding the risk is poor password

security, and the pace of improvement in quantum

computing may soon render these methods moot by

making password permission checks faster than

turning a key in a lock.

Implementing Post-Quantum Cryptography

(PQC) in WordPress: The Kyber encryption

integrated with Dilithium authentication provides

additional security but incurs the different challenges

such as the high computational overhead,

compatibility issues, and user experience concerns.

The challenge is still balancing security with

usability.

Limitations of Existing Encryption Techniques:

AES-256, RSA, and ECC encryption have a potential

risk of being compromised by the application of

quantum algorithms like Shor’s and Grover’s

algorithms in the future. The move to quantum-

resistant cryptography is critical for long-term

security.

3.2 Advancements in Recent Research

Latest Developments of ALLIEIODA: Scalability

and Usability Improvements Cloud systems and

modular software architectures are being developed

to make such digital agriculture solutions cheaper and

more accessible to small scale farmers. Regional

customizations in multi- language platforms are also

gaining interest, to cater to diverse farmer

requirements of different races.

In summary, the findings point out how digital

platforms lead to better productivity and

sustainability while offering additional benefits to the

agriculture sector. Nevertheless, additional research

is needed to delve into the particularities and

advantages of digital platforms in the agricultural

domain, as well as the challenges and constraints of

deploying these platforms across various contexts.

4 PROPOSED METHODOLOGY

Role-Based System Management in WordPress:

The built uses WordPress, one of the most

customizable, open-source content management

systems (CMS) out there with a straightforward user

interface and a large plugin library. With WordPress,

keeping these several complex functions of this

agricultural support system remains the same. The

system makes use of complete modular and

customization capabilities providing full advantages

to three major roles Admin, Farmer, and Advisor.

It allows admins to be the sole judge who

determines the content, users, and the entire system,

and admins control the entire platform. System level

issue management to ensure functionality. They also

facilitate interactions between farmers and advisors,

ensuring that the platform's policies are adhered to

and providing technical or user-related issue

resolution as necessary.

Enhancing User Experience and Accessibility:

Farmer role comes with various tools that can be

used for community engagement, access to resources,

and better productivity. Chat features allow farmers

to communicate between one another collaboratively.

WP User frontend is the plugin used for this feature,

which lets users create and manage content from the

frontend, without giving access to the admin area.

Offering translations in regional languages for every

piece of content ensures that the farmers can

consume it in their own languages, making it

inclusive and accessible.

An important part for farmers is the built-in e-

commerce (WooCommerce plugin). WooCommerce

is one of the most painter's e-commerce disrupting

solutions in the world, allowing farmers to purchase

agricultural products, peddle produce, even rent out

farming implements. This makes it easier for store

owners to get started, and the platform offers features

like secure payment gateways, product listings,

inventory management, and order tracking to

facilitate transparent and smooth transactions.

Integration of WordPress Plugins for Agricultural

Support: using the Amelia plugin a robust booking

and appointment scheduling software. Amelia also

enables users to search advisors by location and

specialty, book sessions, and reschedule or cancel

appointments when necessary. Data is compiled from

advisors who assist farmers, tracking and rating

capabilities to allow farmers to leave ratings and

feedback on help received.

The Advisor role helps you help farmers by

playing it right. The Amelia plugin allows advisors to

create and manage their appointments, as well as use

a dashboard that not only allows for tracking of client

interactions and updates schedules, but also monitors

their feedback. Moreover, advisors can post

educational material and practical solutions to

problems faced by the farmers.

The system is based on a general pattern, starting

with the registration of users that assigns the roles of

Admin, Farmer or Advisor, depending on their

profile. The platform allows farmers to post

questions, have chats, and discuss issues, and

advisors can book appointments and help bring

expertise to their queries. Admins manage this entire

workflow, maintaining quality control and resolving

issues as they come up. Moreover, the e-commerce

platform facilitates the smooth buying and renting of

vital farming needs, thus improving accessibility to

resources.

This platform provides a scalable, user-friendly

and efficient solution, specifically designed to serve

the agricultural community, utilizing its WordPress

and its mighty plugin ecosystem. WP User Frontend,

WooCommerce, and Amelia work in harmony with

one another to give the farmers, the advisors and the

administrators complete all-round experience that

solves the problems faced uniquely by them.

Quantum-Resistant Security Implementation for

WordPress: We focus on enhancing WordPress

security by integrating post-quantum cryptographic

(PQC) techniques, specifically Kyber encryption for

data protection and Dilithium digital signatures for

authentication. Figure 1 show the Flowchart of

complete process. The methodology consists of three

key phases:

• Users generate a quantum-safe digital

signature, which is verified during login,

eliminating phishing risks, credential leaks,

and brute-force attacks (L. Ducas et al., 2017).

4.2 Implementing Kyber Encryption

for Secure Data Storage

• Sensitive user data, including personal and

financial information, is encrypted using

Kyber encryption before being stored in

the database. Figure 3 show the Encrypted

data is saved in Php My Admin.

Figure 3: Encrypted Data Is Saved in Php My Admin.

• Decryption is only possible through

Kyber-secured keys, ensuring quantum-

resistant security for stored data (S. S. Roy

et al., 2022). Figure 4 show the log entry

confirms that encryption and decryption

process is working correctly.

Figure 4: The Log Entry Confirms That Encryption and

Decryption Process Is Working Correctly.

4.3 Developing a Custom WordPress

Plugin

A custom WordPress plugin is created to integrate

Kyber encryption and Dilithium authentication

seamlessly. Figure 5 show the A plugin was created for

Kyber Encryption.

Figure 5: A Plugin Was Created for Kyber Encryption.

Verification Methods.

Figure 7 and 8 shows the Analysis of Kyber with

traditional encryption and Analysis of Dilithium with

traditional verification methods respectively.

Advantages of the Proposed Methodology

• Quantum-Resistant Security: Protects against

future quantum-based cyber threats.

• Fast and Efficient Authentication: Digital

signatures eliminate slow password

verification processes.

• Lightweight and Scalable: Kyber encryption is

computationally efficient, making it ideal for

web applications.

By implementing these PQC techniques, this

project demonstrates the feasibility of securing

WordPress-based platforms without significant

performance trade-offs, paving the way for future

quantum-secure web applications.

5 CONCLUSIONS

In today’s fast-changing digital world, even

agriculture is going high tech and with that comes the

need for stronger security. Our project focused on

creating a safe and simple digital space for farmers,

advisors, and admins by building a WordPress

platform that’s not just functional but also future-

proof. We used advanced security tools Kyber

encryption and Dilithium digital signatures to protect

user data and logins from cyber threats, even the kind

that future quantum computers might bring. We did

this without making things complicated for users.

Farmers can still buy or sell products, book

appointments, or connect with advisors easily, while

their data stays secure behind the scenes. It’s a small

step toward safer digital agriculture, but it can make

a big difference.
