Distributed key generation is one of the most challenging tasks for threshold cryptosystems. Designing such a protocol and proving its security against a malicious, adaptive adver...
Wireless Sensor Networks (WSN) security is an important issue which has been investigated by researchers for few years. The most fundamental security problem in WSN is key manageme...
In a distributed key distribution scheme, a set of servers help a set of users in a group to securely obtain a common key. Security means that an adversary who corrupts some server...
In this paper, we examine a classification of conference key distribution protocols proposed in [4] and show that no known protocol satisfies the security requirements in class 4...
