Abstract: Broadcasting is the distribution of message to dispersed audience via communicating channels. Whereas, multicasting refers to sending of message to a selected group. Key management for multicast and broadcast services has difficulty to find an appropriate security mechanism because, a very high number of users consume data simultaneously. Thus our project is focused on new Key Management Scheme, called 2-way Hash Chains Scheme (2HCS), that focus on the reduction of transmission overhead caused above and thus, effectively reduces the number and the size of keying messages.
Keywords: Communication system security, multimedia systems, security, hash function.
