Enhanced "ULTRA GRIDSEC": Enhancing High Performance Symmetric Key Cryptography Schema Using Pure Peer To Peer Computational Grid Middleware (HIMAN)

ULTRA GRIDSEC" is a high performance symmetric key cryptography schema used to increase the performance of symmetric key encryption algorithms like DES and TDES by decreasing their execution time and increasing their security by using compression and multithreading techniques and other enhancement points. In this paper we enhancing the performance of a "ULTRA GRIDSEC" by using a pure peer-to-peer computational grid middleware called "HIMAN" that we developed before. "ULTRA GRIDSEC" Performance accelerated by about 254.8% when it was applied as an application for "HIMAN" middleware for file with size 55MB and 1MB block size, and accelerated by 431.2% for file with size 110MB and 10MB block size so every time the size of file is large and choosing the suitable block size and suitable number of threads this can cause a great acceleration for the schema performance regarding to machines capabilities of the running middleware. After that we compared the performance of the enhanced "ULTRA GRIDSEC" with a developed schema called "GRIDCRYPT" developed by Melbourne University in Australia and run over their middleware called Alchemi, so for file with size 55MB and 1MB Block Size and using 4 workers, "ULTRA GRIDSEC" Performance is faster by about 445.37% than the "GRIDCRYPT" Schema, and for file with size 110 MB and 10 MB block size and using 4 workers, "ULTRA GRIDSEC" Performance is faster by about 708.69% than the "GRIDCRYPT" schema. An analysis and results of this schema and comparison of this scheme performance with another existing schema are presented in this paper.
