ULTRA GRIDSEC: Peer-to-Peer Computational Grid Middleware Security Using High Performance Symmetric Key Cryptography

"ULTRA GRIDSEC" is a high-performance symmetric key cryptography scheme used to secure data passes inside Peer-to-Peer Computational Grid Middleware that we are developing now[1]. This schema is used to accelerate the performance of Triple data encryption standards(TDES) by about 439.7% and this percentage value is changed according to machine capabilities, also it enhances the security of encrypted TDES files. An analysis and comparison of this scheme and its performance is presented in this paper.
