Abstract

In order to resist against the active attacks,Chen Jia-qi proposed an authenticated tripartite key agreement protocol based on certificateless cryptography in 2010. However,the protocol couldn't resist the passive opponent's attack,and it also couldn't meet some security attributes stated by Chen Jia-qi. In order to solve the above problems,based on an efficient certificateless two-party authenticated key agreement protocol given by He De-biao,this paper proposed a new certificateless authenticated tripartite key agreement protocol. The security and efficiency of the new protocol were analyzed. The result shows that the new protocol satisfies the security properties of the certificateless authenticated tripartite key agreement protocol. Compared with the protocol proposed by Chen Jia-qi,the efficiency of the new protocol is higher,which attributes to the reduced number of pairings in the new protocol.

Authenticated tripartite key agreement protocol based on certificateless cryptography

Jiaqi Chen, Jun Feng, Hao Yan

In order to make key agreement protocol to resist against the active attacks, proposed a certificateless authenticated tripartite key agreement protocol. First, analysed the existing key agreement protocol. Then designed a security tripartite key agreement scheme based on the theory of certificateless cryptography. This protocol builds a security tripartite session key only need one round message exchange, which can strongly overcome the key escrow and offer perfect forward secrecy. The analysis of security and complexity shows that this protocol is secure and effective.

A new method based on certificateless authenticated key agreement protocols

Jun Ma

The tripartite key agreement protocol that Joux has proposed is more efficient and simple,but it is vulnerable to man-in-the-middle attack.A new method based on certificateless authenticated key agreement protocols is proposed,which extends tripartite key agreement to multi-party accompanied by its authentication function.It has a lot of advantages,such as a short signature,high calculation efficiency,simple management about certificate and escrow-free anonymous key.The new method enjoys much secure prosperity,for instance,which has a non-key control and forward security,resists man-in-themiddle and leaked disguise attack,and so on.

Two-party authenticated key agreement in certificateless public key cryptography

Yijuan Shi, Jianhua Li

Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. It combines the advantages of the identity-based cryptography and the traditional PKI. Many certificateless public key encryption and signature schemes have been proposed. However, the key agreement in CL-PKE is seldom discussed. In this paper, we present a new certificateless two party authentication key agreement protocol and prove its security attributes. Compared with the existing protocol, our protocol is more efficient.

Attack and improvement of a certificateless two-party authenticated key agreement protocol

Zhang Quan-lin

This paper analyzed a bilinear pairing-free certificateless two-party authenticated key agreement protocol proposed by Kim et al. The protocol did not satisfy an important security feature that was the basic impersonation attack under public key replacement attack. As well as,it mounted a specific attack on the protocol. Then an improved certificateless two-party authenticated key agreement protocol was presented in order to satisfy the missing security property. The analysis shows that the improved protocol can efficiently withstand public key replacement attack and satisfy some necessary security properties.

A new certificateless authenticated two-party key agreement

YuXiu-Ying, ZhangWen-Fang, HeDa-Ke

Authenticated key agreement (AKA) protocol allows two or multi-parties exchange messages, authenticate each other and establish shared session keys for later secure communications over an open network. The certificateless -based authenticated key agreement protocols combined the advantages of the traditional PKI and the identity-based cryptography. This paper analyzes a proposed AKA protocol[6] and presents a new certificateless AKA protocol. Furthermore, we examines the security of the new protocol and compare it to the existing certificateless key agreement protocols in efficiency. The new proposed scheme achieves almost all of the desired security attributes and is more practicable.
