This paper analyzes the implementation scheme of unicast key-agreement protocol in the WAI by the Strand Space Model,and points out that the security of the implementation scheme is greatly improved as compared with the original scheme.

Study and Design of the Key Negotiation Protocol;

Results show that it can achieve the alleged authentication and key negotiation goals.

Authentication and key negotiation is an elementary protocol in constructing a secure network system,and it is the implementation foundation of the key management protocol and the secure routing protocol.

1-round dynamic group key agreement;

An efficient dynamic group key agreement protocol;

Security analysis of a key agreement protocol for mobile Ad Hoc network;

The secret-key rate of unconditionally-secure secret-key agreement based on smooth entropy;

This paper investigates the effect of side-information,obtained by the opponent through an initial reconciliation step,on the size of the secret-key that can be distilled safely by subsequent privacy amplification in uncoditionally-secure secret-key agreement protocol based on smooth entropy,and obtains the size of the secret-key with some probability.

Information-theoretically secure secret-key agreement is the key to make perfect security.

Efficient anonymous password-based authenticated key exchange scheme

Consisting of key exchange protocol and packet check protocol,it implements dual authentication between hosts,and guarantees the authenticity and integrity of packets in transmission.

Most password-based key exchange protocols consider how to exchange a session key between a client and a server.

Efficient distributed group key agreement scheme;

Novel group key agreement protocol for dynamic collaborative peer groups;

Efficient group key agreement protocol for large Ad hoc networks;
