International audience; Cramer-Shoup was the first practical adaptive CCA-secure public key encryption scheme. We propose a faster version of this encryption scheme, called Fast Cramer-Shoup. We show empirically and theoretically that our scheme is f

On the Security of a Variant of ElGamal Encryption Scheme

Autor: Fang-Yu Rao

Publikováno v: IEEE Transactions on Dependable and Secure Computing. 16:725-728

Recently, based on the Paillier cryptosystem [1] , Yi et al. outline a distributed ElGamal cryptosystem which allows for both a much simpler distributed key generation procedure and a more efficient distributed decryption of messages from a large pla

Cryptanalysis and security improvement for a symmetric color image encryption algorithm

Autor: Thang Manh Hoang, Hoang Xuan Thanh

Publikováno v: Optik. 155:366-383

This paper presents the weaknesses in the cryptosystem proposed by W. Zhang and his colleagues. The proposed method to restore the permutation rule is based on the chosen-ciphertext attack. The method is successful in restoration of the permutation r

Modified optical asymmetric image cryptosystem based on coherent superposition and equal modulus decomposition

Autor: Xueju Shen, Jianjun Cai

Publikováno v: Optics & Laser Technology. 95:105-112

We propose a modified optical asymmetric cryptosystem based on coherent superposition and equal modulus decomposition (EMD). In the encryption process, the asymmetric cells of the previous cryptosystem is cascaded, while some small changes are made.

Ciphertext-Only Attack on Linear Feedback Shift Register-Based Esmaeili-Gulliver Cryptosystem

Autor: Yongwoo Lee, Young-Sik Kim, Jong-Seon No

Publikováno v: IEEE Communications Letters. 21:971-974

Esmaeili and Gulliver recently proposed a secret key cryptosystem based on error-correcting codes in which a codeword modified by random insertions, deletions, and errors is used as a ciphertext. The secret keys used in this cryptosystem consist of r
