This paper presents an effective method to integrate the revocation mechanism into some group signature schemes that are based on the strong RSA assumption. The mechanism enables the group manager to either update a group member’s certificates, or revoke a group member. More specifically, a generic method has been proposed for the protocols of sign, verify, and revocation. We demonstrate the ef...
When a group key exchange protocol is executed, the session key is typically extracted from two types of secrets; long-term keys (for authentication) and freshly generated (often random) values. The leakage of this latter so-called ephemeral keys has been extensively analyzed in the 2-party case, yet very few works are concerned with it in the group setting. We provide a generic group key excha...
In sensor networks, sensors are likely to be captured by attackers because they are usually deployed in an unprotected or even a hostile environment. If an adversarial compromises a sensor, he/she uses the keys from the compromised sensor to uncover the keys of others sensors. Therefore, it is very important to renew the keys of sensors in a proactive or reactive manner. Even though many group ...
