Weakness of Several Identity-based Tripartite Authenticated Key Agreement Protocols
Key agreement allows multi-parties exchanging public information to create a common secret key that is known only to those entities over an insecure network. In recent years, several identity-based authenticated key agreement protocols have been proposed. In this study, we analyze three identity-based tripartite authenticated key agreement protocols. After the analysis, we found that these prot...
متن کاملIdentity Based Authenticated Key Agreement Protocols from Pairings
We investigate a number of issues related to identity based authenticated key agreement protocols in the Diffie-Hellman family enabled by the Weil or Tate pairings. These issues include how to make protocols efficient; to avoid key escrow by a Trust Authority (TA) who issues identity based private keys for users, and to allow users to use different TAs. We describe a few authenticated key agree...
متن کاملComparative Study of Tripartite Identity-Based Authenticated Key Agreement Protocols
Key agreement protocols are used to exchange keys between two or multiple entities. The exchanged key can be later used to assure confidentiality through encryption. Additionally authenticated key agreement protocols offer implicit authentication. In this paper we conduct a security and efficiency comparison of tripartite authenticated identity-based key agreement protocols and review all of th...
متن کاملCryptanalysis on Identity-based Authenticated Key Agreement Protocols from Pairings
Two-party authenticated key agreement protocol is used to authenticate entities and establish session keys in an open network in order to provide secure communications between two parties. Several security attributes are highly desired for such protocols, such as perfect forward secrecy (the corruption of long-term keys of all the entities should not compromise any session key), PKG forward sec...
متن کاملStrongly-Secure Identity-Based Key Agreement and Anonymous Extension
We study the provable security of identity-based (ID-based) key agreement protocols. Although several published protocols have been proven secure in the random oracle model, only a weak adversarial model is considered – the adversary is not allowed to ask Session-Key Reveal queries that will allow the adversary to learn previously established session keys. Recent research efforts devoted to pro...
