Identity-based password authentication scheme for Ad hoc networks
Qingying Sun · Computer Engineering and Applications Journal · 2013
This paper binds password and identity using the digital signature to prevent the impersonation attack from malicious nodes, and resists repudiation of internal nodes. The scheme uses forward hash chains to update password, and decreases node’s computational load and storage requirements. The proposed schema generates a session key with Diffie-Hellman key exchange protocol, it reduces the probability of attack due to prolonged storage of key.
