Abstract

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.

Certificateless authenticated tripartite key agreement protocol

LI Xu-don

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.

Secure and Efficient Two-Party Authenticated Key Agreement Protocol from Certificateless Public Key Encryption Scheme

Mengbo Hou, Qiuliang Xu

As the fundamental building block for secure communication in the open network, authenticated key agreement protocols are usually constructed in the public key setting. Certificateless public key cryptography combines the advantage of the identity-based public key cryptography (ID-PKC) and the traditional PKI. In this paper, we present a secure and efficient two-party authenticated key agreement protocol based on the efficient certificateless public key encryption scheme due to Cheng and Comley. Security analysis shows that it achieves perfect forward secrecy, PKG forward secrecy and almost all the other known security attributes for authenticated key agreement protocol, such as known-key secrecy, key-compromise impersonation resilience, unknown key-share resilience, known session-specific temporary information security, message independence and no key control. Compared to other comparable schemes, it is more secure and has nice efficiency.

Secure certificateless-based authenticated key agreement protocol in the client-server setting

Mengbo Hou, Qiuliang Xu

E-learning communication security should be considered to ensure sensitive message transmission. Authenticated key agreement protocol in the client- server setting is the fundamental building block for ensuring client-server entity authentication, data confidentiality and integrity. So far, great deals of two- party authenticated key agreement protocols were proposed based on traditional public key cryptography and identity-based cryptography, but the certificateless-based authenticated key agreement protocol is seldom discussed. In this paper, we propose such a secure protocol from a certificateless public key encryption scheme due to Park et al. Compared to other comparable protocols, it achieves more security attributes, such as no-key escrow, perfect forward secrecy, known session-specific temporary information security and no-key control etc. Meanwhile, it keeps nice efficiency.

A New Method based on Certificateless Authenticated Group Key Agreement Protocols

Ma Ju

A new method based on certificateless authenticated key agreement protocols is proposed.A generalization of multi-party in Nalla agreement and tripartite key agreement,which can strongly overcome the key escrow is made.This new method shows that there is a short signature,which can increase theefficiency ofauthentication process.And it has used the key seed and password evolution scheme,which improved the security of the protocol.The new agreement satisfies much secure prosperity,for instance,forward security,against manin-the-middle resistance,impersonation attack resistance,and so on.

Constructing certificateless-based two-party authenticated key agreement protocol

Han Jiang

The certificateless -based authenticated key agreement protocols have the advantages of simplicity of managing identities compared to the PKI-based schemes,as well as avoiding the key escrow issues inherited in the identity-based schemes. This paper proposes a two-party certificateless-based authenticated key agreement scheme based on a provably secure certificateless-based public key encryption scheme.The comparisons with other comparable schemes in security and efficiency show that,the new scheme achieves more of the desired security attributes,such as perfect forward secrecy,PKG forward secrecy,known session-specific temporary information secrecy and key escrowless.Meanwhile it keeps the nice computational efficiency.

Authenticated key agreement protocol is the fundamental building block for secure communication in the open network to ensure authentication and confidentiality of e-commerce and e-government applications. Certificateless public key cryptography combines the advantage of the identity-based public key cryptography (ID-PKC) and the traditional PKI. In this paper, we present a secure and efficient two-party authenticated key agreement protocol based on an efficient and secure certificateless public key encryption scheme. It achieves almost all the known security attributes for authenticated key agreement protocol, such as perfect forward secrecy, PKG forward secrecy, key-compromise impersonation resilience, unknown key-share resilience, message independence and no key control. Compared to other comparable schemes, it is more secure and has nice efficiency.
