New Single-Trace Side-Channel Attacks on a Specific Class of Elgamal Cryptosystem
Elgamal cryptosystem Side-channel attacks Montgomery Ladder
2018/8/21
In 2005, Yen et al. proposed the first N−1N−1 attack on the modular exponentiation algorithms such as BRIP and square-and-multiply-always methods. This attack makes use of the ciphertext N...
Can one use the discrete logarithm problem in matrix groups, to build a better and secure cryptosystem? We argue, it is indeed the case. This makes the group of circulant matrices suitable and attract...
A SIMPLE GENERALIZATION OF THE ELGAMAL CRYPTOSYSTEM TO NON-ABELIAN GROUPS II
MOR cryptosystem special linear groups

In this paper I study the MOR cryptosystem using the special
linear group over finite fields. At our current state of knowledge,
I show that the MOR cryptosystem is more secure than the ElGamal
cry...
