Relatively-Sound NIZKs and Password-Based Key-Exchange
NIZKs Relatively-Sound Key-Exchange
2012/3/26
We define a new notion of relatively-sound non-interactive zero-knowledge (NIZK) proofs, where a private verifier with access to a trapdoor continues to be sound even when the Adversary has access to ...
Password Based Key Exchange with Hidden Elliptic Curve Public Parameters
Password Based Key Exchange Hidden Elliptic Curve Public Parameters
2009/9/27
We here describe a new Password-based Authenticated Key Exchange (PAKE) pro-
tocol based on elliptic curve cryptography. We prove it secure in the Bellare-Pointcheval-Rogaway
(BPR) model. Our propos...
Security Proofs for an Efficient Password-Based Key Exchange
Security Proofs Efficient Password-Based Key Exchange
2009/4/15
Password-based key exchange schemes are designed to provide entities communicating over
a public network, and sharing a (short) password only, with a session key (e.g, the key is used for data
integ...
Password Based Key Exchange With Mutual Authentication
Password Based Key Exchange Mutual Authentication
2009/3/27
A reasonably efficient password based key exchange (KE) protocol with provable security
without random oracle was recently proposed by Katz, et al. [18] and later by Gennaro and Lindell
[13]. Howeve...
Security Weakness in a Three-Party Password-Based Key Exchange Protocol Using Weil Pairing
Key exchange protocol password-based authentication Weil pairing
2009/2/24
Recently, Wen, Lee, and Hwang proposed a three-party password-authenticated key ex-
change protocol making use of the Weil pairing. The protocol was claimed to be provably
secure. But despite the cl...
Universally Composable Password-Based Key Exchange
key exchange password-based protocols universal composability
2009/2/13
We propose and realize a de nition of security for password-based key exchange within the
framework of universal composability (UC), thus providing security guarantees under arbitrary
composition wi...
Hybrid Protocol For Password-based Key Exchange in Three-party Setting
Password-based Universally composable Key exchange
2009/1/6
Modular design is a common approach for dealing with complex tasks in modern cryptology. The critical of this approach is that designing a secure hybrid protocol. In this paper, we study password-base...
