EVALUATION OF CRYPTOGRAPHIC ALGORITHMS
This article represents a synthesis of the evaluation methods for cryptographic algorithms and of their efficiency within practical applications. It approaches also the main operations carried out in cryptanalysis and the main categories and methods of attack in order to clarify the differences between evaluation concept and crypto algorithm cracking.cryptology, cryptanalysis, evaluation and cracking cryptographic algorithms

System approach to disparity estimation
A system approach to disparity estimation using dynamic programming is presented. The four step system can calculate a dense correspondence map between a stereo pair with parallel or
nonparallel camera geometry. Results are presented with CCIR 601 format stereo images
A Comparison of Cryptography Courses
The author taught two courses on cryptography, one at Duke University aimed
at non-mathematics majors and one at Rose-Hulman Institute of Technology aimed
at mathematics and computer science majors. Both tried to incorporate technical
and societal aspects of cryptography, with varying emphases. This paper will
discuss the strengths and weaknesses of both courses and compare the
differences in the author's approach.Comment: 14 pages; to appear in Cryptologi
A Meaningful MD5 Hash Collision Attack
It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision. Vlastimil Klima then proposed a more efficient and faster technique to implement this attack. We use these techniques to first create a collision attack and then use these collisions to implement meaningful collisions by creating two different packages that give identical MD5 hash, but when extracted, each gives out different files with contents specified by the atacker
