Robust attributes-based authenticated key agreement protocol using smart cards over home network

Abstract

Authenticated key agreement protocol is one of the most convenient ways to provide secure authentication and key agreement for the communication between the user and the service provider over insecure network. Recently, Lee proposed an attributes-based authenticated key agreement protocol over home network, which is based on the attribute based cryptosystem. He claimed that his protocol is secure against replay attack, impersonal attack, man-in-the-middle attack, password guessing attack and forward secrecy. However, this paper points out that Lee's protocol still has a security flaw in password guessing attack. To solve the problem in Lee's scheme, we propose a robust attributes-based authenticated key agreement protocol using smart cards over home network. © 2011 Springer-Verlag.
