Abstract:
Storing highly confidential data and carrying out security-related operations are crucial to many systems. Starting
from an industrial use case we propose a generic architecture based on secret sharing which address critical
operation authorization. By comparing and benchmarking different scheme from the literature we analyze the
different trade-offs (security, functionality, performance) which can be achieved. Finally by providing an open
source .NET implementation of several secret sharing schemes, this paper aims to rise awareness regarding
the capabilities of such algorithms to increase security in industrial setting.
