Paper: Testing Randomness in Ciphertext of Block-Ciphers Using DieHard Tests

ABSTRACT One of the important aspects of the security of block ciphers is the randomness of the cipher text. One criterion used to evaluate the Advanced Encryption Standard (AES) candidate algorithms was their demonstrated suitability as random number generators. In this paper, we introduced a new approach to interpret the results of tests of randomness.… Read More »

Paper: Design of H.323 Secure IP-Telephony Framework

ABSTRACT The paper is aimed to provide a secure IP-Telephony system based on H.323 set of protocols. H.323 is a standard that specifies the components and procedures that provide multimedia communication services—real-time audio, video, and data communications—over packet networks, including Internet protocol (IP)–based networks. H.323 is part of a family of ITU—T recommendations called H.32x… Read More »
