Abstract. We examine the popular proof models for group key establishment of Bresson et al. [BCPQ01,BCP01] and point out missing security properties addressing malicious protocol p...

: Wireless Sensor Networks (WSN) pose a need for dynamically establishing a secret key joint to a group of nodes. Elliptic Curve Cryptography (ECC) has emerged as a suitable public...
A Group Key Agreement protocol is a process to establish a cryptographic key for a group of participants over an open network. In this paper, we propose a group key agreement(CAGKA...
Traditional key management techniques, such as public key cryptography or key distribution center (e.g., Kerberos), are often not effective for wireless sensor networks for the se...
