Security of the electronic commercial transaction especially through the information communication network is gaining its significance due to rapid development of information and communication related fields. For that, some kind of cryptographic algorithm is already in use for the smart card. However, the growing needs of handling multimedia and real time communication bring the smart card into more stringent use of its resources. Therefore, we proposed a key scheduler block of the smart card to facilitate multimedia communication and real time communication.
