A threshold authenticated encryption scheme using hybrid problems
M. S. A. Mohamad, Eddie Shahril Ismail · Applied Mathematical Sciences · 2014
In this paper, we propose a threshold authenticated encryption scheme using both factoring and discrete logarithm problems.We apply the concept of threshold cryptography in the verification and message recovery phase, where t out of n recipients are required to verify and recover the message. Security analysis shows that our scheme will remain secure even if one of these problems can be solved.
