Comment: "Eenhanced novel access control protocol over wireless sensor networks"
Jian Jun Shen, Sangman Moh, Ilyong Chung · IEEE Transactions on Consumer Electronics · 2010
In a recent paper in this journal, an enhanced novel access control protocol (ENACP) over wireless sensor networks was given for the problem of preventing malicious nodes from joining the sensor network based on elliptic curve cryptography (ECC) and hash chain. We show that the presented ENACP has a fatal weakness such that it is insecure to the active attack.
