This key must be updated and distributed each time a new member joins the group or a current one leaves it. Because of its dependency on time-consuming cryptographic operations this rekeying process can become a bottleneck in the Pay-TV system over Internet. This book tackles this problem by providing novel high-performance architectures, called rekeying processors, which act as coprocessors in the...
