Abstract

We point out the RYY+ identity-based (ID-based) key agreement protocol is vulnerable to Key-compromise impersonation (KCI) attack and Intermediate results leakage (IRL) attack. Then we give the improved protocol which provides KCI and IRL resistance. The novel protocol is provably secure under the gap Bilinear Diffie-Hellman assumption in the seCK model, which enhances the adversary's queries comparing with previous ID based AKE models. The proposed scheme also has an advantage over most previous schemes on security and efficiency.

An Improved Provably Secure Identity-Based Authenticated Key Agreement Protocol

Yang Li, Jianming Zhu, Wei Zhang +1 more

We revisit the identity-based (ID-based) key agreement protocol due to Wang et al. The protocol is highly efficient and suitable for practical applications except being vulnerable to Intermediate results leakage (IRL) and Key-compromise impersonation (KCI) attack. We propose an improved protocol following the Full Dual Exponential Challenge Response (FDCR-1) scheme to ensure the signature change every time. We also prove it to be secure in the strengthened extended Canetti -- Krawczyk (seCK) model provides better support for adversary's query than previous. In addition, the improved protocol also has an advantage over most existing protocols on security and efficiency.

RYY ++ : A Novel Provably Secure Identity‐Based Authenticated Key Agreement Protocol

Yang Li, Jianming Zhu, Ning Zhang +2 more

Based on revisiting the RYY+ Identitybased (ID-Based) key agreement protocol, we find it’s vulnerable to Intermediate results leakage (IRL) and Keycompromise impersonation (KCI) attack. A novel protocol called RYY++ is proposed to make up for its deficiencies. Our protocol follows the Full dual exponential challenge response (FDCR-1) scheme to ensure the signature change every time, so the master public key of Private key generator (PKG) joined in signature generation can guarantee two parties trust each other. The RYY++ protocol is also proven to be secure in the Strengthened extended Canetti– Krawczyk (SeCK) model which provides better support for adversary’s query and has an advantage over most existing protocols on security and efficiency.

Security-provable Identity-based Authenticated Key Agreement Protocol

Yafei Wang

Most Identity-based Authenticated Key Agreement(ID-AKA) protocols have poor performance on security and the efficiency.To solve this problem,this paper presents an improved ID-AKA protocol.Security proof with the modular approach in the mBR model is provided,which means the new protocol satisfies perfect forward security,PKG forward security,resistant to key-compromise impersonation.Furthermore,the new protocol can satisfy resistance to leakage of ephemeral secrets.Compared with previous ID-AKA protocols which can satisfy the same security properties,the new protocol has higher efficiency.

An ID-based authenticated key exchange protocol based on bilinear Diffie-Hellman problem

Hai Huang, Zhenfu Cao

In this paper, we present a new ID-based two-party authenticated key exchange (AKE) protocol, which makes use of a new technique called twin Diffie-Hellman problem proposed by Cash, Kiltz and Shoup. We show that our scheme is secure under bilinear Diffie-Hellman (BDH) assumption in the enhanced Canetti-Krawczyk (eCK) model, which better supports the adversary's queries than previous AKE models. To the best of our knowledge, our scheme is the first ID-based AKE protocol provably secure in eCK model.

New Identity-based Authenticated Key Agreement Protocol

Hui Ding, Yin Xin-chun

This paper designs an identity-based authenticated key agreement protocol with perfect forward security of Private Key Generator(PKG).It is proved to provide known key security,forward secrecy,key-compromise impersonation and so on in standard model.Its security is based on Bilinear Decisional Diffie-Hellman(BDDH) assumption,so its security is higher than the protocols based on the weaker assumption.

A New Identity-Based Tripartite Authenticated Key Agreement Protocol

Hongyuan Wang

Now,most of the tripartite authenticated key agreement protocols have been proven to be insecure.We design the new identity-based tripartite authenticated key agreement protocol,it is based on the secure IBE scheme by Peng.This protocol's security based on bilinear decisional Diffie-Hellman assumption.This protocol could provide known key security,PKG forward secrecy,key-compromise impersonation resilience and unknown key-share resilience,so it's a secure tripartite authenticated key agreement protocol.
