Chinese remainder theorem based group key management
In this paper, we present two new centralized group key management protocols based on the Chinese Remainder Theorem (CRT). By shifting more computing load onto the key server we o...

Unbelievable Security. Matching AES Security Using Public Key Systems
The Advanced Encryption Standard (AES) provides three levels of security: 128, 192, and 256 bits. Given a desired level of security for the AES, this paper discusses matching publi...
