Extending the ElGamal Cryptosystem to the Third Group of Units of $\Z_{N}$

In this paper, we extend the ElGamal cryptosystem to the third group of units of the ring $\Zn$, which we prove to be more secure than the previous extensions. We describe the arithmetic needed in the new setting. We also provide some numerical simulations that shows the security and efficiency o...

Fast Plaintext-Ciphertext Matrix Multiplication from Additively Homomorphic Encryption
