Towards a Provably Secure DoS-Resilient Key Exchange Protocol with Perfect Forward Secrecy
Just Fast Keying (JFK) is a simple, efficient and secure key exchange protocol proposed by Aiello et al. (ACM TISSEC, 2004). JFK is well known for its novel design features, notably its resistance to denialof-service (DoS) attacks. Using Meadows’ cost-based framework, we identify a new DoS vulnerability in JFK. The JFK protocol is claimed secure in the Canetti-Krawczyk model under the Decisiona...
متن کاملProviding perfect forward secrecy for location-aware wireless sensor networks
Sensor nodes are resource-constrained, such as low battery life, computation, bandwidth and memory, so traditional public key schemes are impractical in wireless sensor networks. In the previous schemes, symmetric cryptography is the most common method used in sensor nodes. How to distribute keys into every sensor node is an important issue in many applications for hierarchical sensor networks....
متن کاملOne-round Strongly Secure Key Exchange with Perfect Forward Secrecy and Deniability
Traditionally, secure one-round key exchange protocols in the PKI setting have either achieved perfect forward secrecy, or forms of deniability, but not both. On the one hand, achieving perfect forward secrecy against active attackers seems to require some form of authentication of the messages, as in signed Diffie-Hellman style protocols, that subsequently sacrifice deniability. On the other h...
متن کاملAn Improved Conference-Key Agreement Protocol with Forward Secrecy
Recently, Tzeng proposed a provably secure and fault-tolerant conference-key agreement protocol. It requires only a constant number of rounds to establish a conference key among all honest participants. This article will show that Tzeng’s protocol does not offer forward secrecy. We say that a conference-key agreement protocol offers forward secrecy if the long-term secret key of any participant...
متن کاملStrongly Secure One Round Authenticated Key Exchange Protocol with Perfect Forward Security
This paper investigates the two-pass authenticated key exchange protocol in the enhanced Canetti-Krawczyk (eCK) with perfect forward security. Currently, there exist no authenticated key exchange protocols which are provably secure in eCK model and meanwhile achieve perfect forward security against active adversary in one round. We propose a new two-pass authenticated key exchange protocol whic...
