Rethinking the security of some authenticated group key agreement schemes
نویسندگان
چکیده
In this paper we analyse three improved authenticated group key agreement schemes, all of which are based on the conference key distribution systems proposed by Burmester and Desmedt. We show that all the schemes suffer from a type of impersonation attack, although these schemes are claimed to be secure.

متن کاملSecurity Properties of Two Authenticated Conference Key Agreement Protocols
In this paper we analyse the security of two authenticated group key agreement schemes based on the group key agreement protocol of Burmester and Desmedt. One scheme was proposed by Burmester and Desmedt, and uses a separate authentication scheme to achieve authentication among the participants. We show that this scheme suffers from a number of security vulnerabilities. The other scheme was gen...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...
متن کاملOn the Security of Some Password-Based Key Agreement Schemes
In this paper we show that two potential security vulnerabilities exist in the strong password-only authenticated key exchange scheme due to Jablon. Two standardised schemes based on Jablon’s scheme, namely the first passwordbased key agreement mechanism in ISO/IEC FCD 11770-4 and the scheme BPKAS-SPEKE in IEEE P1363.2 also suffer from one or both of these security vulnerabilities. We further s...
