Security Analysis and Extensions of the PCB Algorithm for Distributed Key Generation

چکیده
Poovendran, Corson and Baras presented a distributed cryptographic key generation algorithm that was suitable for wireless networking environment. However, the security as well as the computational complexity of their scheme were never analyzed. In this work, we present information theoretic analysis of their work and derive the properties of the cryptographic keys that are generated by their scheme. We also present efficient computational schemes that would require only logarithmic number of steps in group size to compute the common keys.

Distributed Generation Effects on Unbalanced Distribution Network Losses Considering Cost and Security Indices
Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...

متن کاملComparison of two Public Key Cryptosystems
Since the time public-key cryptography was introduced by Diffie andHellman in 1976, numerous public-key algorithms have been proposed. Some of thesealgorithms are insecure and the others that seem secure, many are impractical, eitherthey have too large keys or the cipher text they produce is much longer than theplaintext. This paper focuses on efficient implementation and analysis of two mostpo...
