Optimal Unconditionally Secure ID-Based Key Distribution Scheme for Large-Scaled Networks

摘要

EFficient ID-based key sharing schemes are de- sired wordwide in order to obtain secure communications on the Internet and other related networks, and Key Pre-distribution System (KPS) is one of the majority of such key sharing schemes. The remarkable property of KPS, is that, user need only input the partner's identifier to the secret KPS-algorithm in order to share a key between them. Although this is just a small part of many advantages KPS has in terms of efficiency, an enormous amout of memory is always required to achieve perfect security.
