Abstract

A key management and authentication model is proposed based on elliptic curve combined public key scheme and threshold cryptosystem. In the initialization phase, a trusted authentication centre is needed, while in the operation phase, the key update, revocation, and the shared private-seed-key matrix update are self-organized. Based on the model, an authentication and key agreement protocol without public key transfer and certificate support is proposed. Compared with the certificate-based and the identity-based models, the new model is more suitable for the privacy and authentication in secure ad hoc network.
