Abstract

A two-message two-party key agreement protocol with explicit authentication provides perfect forward secrecy. Digital signatures can usually be used as providing explicit authentication for a key agreement protocol. Shim proposed an efficient identity-based signature scheme using bilinear pairings; however, he did not give a formal security proof for it. In this paper, we present a formal security proof for Shim's signature scheme. Using Shim's signature scheme as building blocks, we propose a new two-party identity-based key agreement protocol with explicit authentication. The proposed protocol satisfies a set of desirable security properties. Compared with the related protocols, the proposed protocol has distinct advantages in terms of security and computational efficiency.

An Efficient Tripartite Identity-Based Authenticated Key Agreement Protocol

Xiaotong Fu, Shufang Guo, Ruijun Shi

In this paper, the tripartite identity-based key agreement is investigated. Inspired by designated verifier signature schemes, a tripartite identity-based key agreement protocol with explicit authentication is proposed with the good authentication of signatures. The new protocol can achieve remarkable security properties, such as perfect forward secrecy and unknown key share. More theoretically, the security proving of the protocol is given in the random oracle model under the Bilinear Diffie-Hellman assumption. The efficiency of the protocol is lying on that three parties can establish an agreed session key after only one round of message exchange. Detailed efficiency analysis compared with other protocols is also made.

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.

A Secure ID-Based Explicit Authenticated Key Agreement Protocol without Key Escrow

Mengbo Hou, Qiuliang Xu

Key agreement protocols are essential for secure communications in open and distributed environments. Identity-based cryptography has become extremely fashionable in the last few years for its special advantages. In this paper, we point out some flaw in the scheme proposed by Wang et al., then we present a two-party identity-based explicit authenticated key agreement protocol with key confirmation, which was inspired on a new identity-based encryption scheme first proposed by Gentry and can be used properly in the escrowless mode. The scheme captures the attributes of known-key secrecy, key-compromise impersonation resilience, unknown key-share resilience, perfect forward secrecy, and no-key control. Especially, the scheme captures the PKG forward secrecy property. The PKG still could not recover all the userspsila past session keys even he knows the long-term private keys of all users.

Certificateless two-party authenticated key agreement protocol based on bilinear pairings

Yuezhi Zhou

Certificateless public key cryptography has appealing features,namely it does not require the use of certificates and does not have a private key escrow feature.This paper describes a certificateless key agreement protocol based on bilinear pairings.The identity authentication in the protocol depends on a digital signature scheme.This paper proves the security of the signature scheme.The results show that in the random oracle model with the discrete logarithm assumption,the signature scheme resists existential forgeries against adaptive chosen-message attacks.The results farther show that the protocol preserves the desired security properties,including known-key security,unknown key-share resilience,perfect forward secrecy,key-compromise impersonation resilience and leakage of ephemeral private key resilience.The protocol requires much lower computation overhead than related protocols,since it uses fewer bilinear pairing operations and no modular exponentiation.

An efficient and secure one-round authenticated key agreement protocol without pairings

Mengbo Hou, Qiuliang Xu

Two-Party Authenticated key agreement protocol is essential for setting up the common session key for parties to establish secure channel for network communication in the open environment. Most of proposed schemes require expensive bilinear pairing operation and only provide limited security attributes. So such protocols are unsuitable for real-world applications that require stronger sense of secrecy. In this paper, we first analysis two schemes recently proposed by Cao etc., and then present a one-round ID-based authenticated key agreement protocol with more desired security attributes, which need no pairing operations while still achieve nice computational efficiency. These security attributes include known-key secrecy, perfect forward secrecy, PKG forward secrecy, key-compromise impersonation resilience, unknown key-share resilience and no key control. Moreover, it captures the enhanced security attributes known session-specific temporary key information secrecy, which means that even the ephemeral secret key were compromised, the adversary can hardly acquire the agreed session key.
