CPK-Based Key-Establishment and Authentication Protocol

Wireless sensor networks are confronted with unique challenges. Key distribution is one of the most challenging security problems in wireless sensor networks, and the traditional security techniques used in tradition networks cannot be applied directly. We propose CPK-based authentication protocol as the security scheme, which can achieve the key establishment and security authentication. In contrast to previous key-establishment solutions, our approaches need small storage space, and can gain stronger security and reasonable performance efficiency.
