Cryptanalysis of an Anonymous Authentication and Key Agreement Protocol for Secure Wireless Body Area Network
Mohammad Amin Rakeei and Farokhlagha Moazami
Abstract: Recently, Kumar and Chand proposed an
anonymous authentication protocol for wireless body area
network. They claimed that their scheme meets major security
requirements and is able to resist known attacks. However, in this
paper we demonstrate that their scheme is prone to traceability
attack. Followed by this attack, an attacker can launch a man-in-the-middle attack and share a session key with the victim node,
and hence the scheme does not achieve secure authentication. Also,
we show that this protocol does not provide perfect forward
secrecy which considered as a key security property in the design
of any secure key agreement protocol.
