Presenting components on the web192 bits, the security claim of MV3 is that no attack faster than the exhaustive key search can be mounted for keys of length up to 256 bits..This paper provides a distinguishing attack on the MV3 stream cipher. We will show that the key stream generated in MV3 is distinguishable from random sequenc

Chosen-Ciphertext Secure Proxy Re-encryption without Pairingsut learning the underlying plaintext. Proxy re-encryption has found many practical applications, such as encrypted email forwarding, secure distributed file systems, and outsourced filtering of encrypted spam. In ACM CCS’07, Canetti and Hohenberger presented a proxy re-encryption scheme with chosen-

Hybrid Damgård Is CCA1-Secure under the DDH Assumptionsteen proved its CCA1-security under a more standard but still new and strong assumption. The known CCA2-secure public-key cryptosystems are considerably more complicated. We propose a hybrid variant of Damgård’s public-key cryptosystem and show that it is CCA1-secure if the used symmetric cryptosys
