Now-a-days security is very essential measure during the data transmission, the authors introducing an efficient mechanism of group key protocol and high complex cryptographic algorithm. They consider how the chaotic maps can be improved to fulfill the cryptographic demands. To achieve this, they extend the domain of chebyshev maps from real number set to finite field. Based on this extension, this paper proposes a novel multicast key exchange algorithm and an efficient cryptographic algorithm for secure data transmission.
