Query: Error Detection and Correction for Distributed Group Key Agreement
  Protocol   Integrating an efficient Error detection and correction scheme with less
encoding and decoding complexity to support the distribution of keying material
in a secure group communication is an important issue, since the amount of
information carried out in the wireless channel is high which produces more
errors due to noise available in the communication channel. Moreover, the key
must be sent securely to the group members. In this paper, we propose a new
efficient group key computation protocol that provides more security and also
integrates an encoding method in sender side and decoding method in the
receiver side. To achieve security in key computation process, we propose
Euler's totient function based Diffie-hellman key distribution protocol. To
provide efficient error detection and correction method while distributing the
Keying and re-keying information, we introduce tanner graph based encoding
stopping set construction algorithm in sender and receiver side of the group
communication. Two major operations in this scheme are joining and leaving
operations for managing group memberships. The encoding and decoding complexity
of this approach is computed in this paper and it is proved that this proposed
approach takes less decoding time complexity.
