Abstract: Group Off-the-Record (GOTR) (Bian et al., 2007) was proposed to address the privacy protection concerns in online chat room systems. It extended the original two-party OTR protocol to support more users while preserving the same security properties. A literature survey of different Diffie-Hellman (D-H) conference key implementations will be given to justify that in an application like a chat room, the virtual server approach is truly the most efficient way to establish a private communication environment among a group of people. However, GOTR’s virtual server approach raises a trustworthiness concern of the chosen chair member. Since the chair member has full control over all encryption keys, there is no constraint to prevent him / her from altering the messages while relaying them. In this paper, we present a study of the GOTR protocol and a solution to the virtual server’s trustworthiness problem via employing an additional MD5 integrity check mechanism. Having such an algorithm, ma kes the GOTR protocol more secure, in that, it gives the other chat members an opportunity to be aware of any potential changes made by the chair member. (More)
