IBAKE: Identity-Based Authenticated Key Exchange Protocol
The past decade has witnessed a surge in exploration of cryptographic concepts based on pairings over Elliptic Curves. In particular, identity-based cryptographic protocols have received a lot of attention, motivated mainly by the desire to eliminate the need for large-scale public key infrastructure. We follow this trend in this work, by introducing a new Identity-Based Authenticated Key Excha...
متن کاملPartitioned Group Password-Based Authenticated Key Exchange
Group Password-Based Authenticated Key Exchange (GPAKE) allows a group of users to establish a secret key, as long as all of them share the same password. However, in existing GPAKE protocols as soon as one user runs the protocol with a non-matching password, all the others abort and no key is established. In this paper we seek for a more flexible, yet secure, GPAKE and put forward the notion o...
متن کاملID-Based Group Password-Authenticated Key Exchange
Password-authenticated key exchange (PAKE) protocols are designed to be se-cure even when the secret key used for authentication is a human-memorable password. In thispaper, we consider PAKE protocols in the group scenario, in which a group of clients, each ofthem shares a password with an “honest but curious” server, intend to establish a common secretkey (i.e., a group key) wi...
متن کاملSecure Authenticated Key Exchange Protocol
From Seo and Sweeney proposed SAKA (Simple Authenticated Key agreement Algorithm), many SAKA variants were proposed to cope with the weaknesses in SAKA. However, they still are vulnerable to off-line password guessing attack. This paper proposes a new secure authenticated key exchange protocol that can resist off-line password guessing attack. To solve the vulnerability of former protocols, key...
متن کاملIdentity Based Authenticated Group Key Agreement Protocol
An important and popular trend in modern computing is to convert traditional centralized services into distributed services spread across multiple systems and networks. One-way function trees can be used to extend two-party Key Agreement protocols to n-party protocols. Tree-based Group Diffie-Hellman [17] is one such protocol. This paper proposes the first Identity based Group Key Agreement pro...
