Özet
In this paper, we propose a new N-tier sAtellite Multicast sEcurity Protocol based on multi-recipient Signcryption schemes (NAMEPS). Our protocol is especially designed for very large and highly dynamic satellite multicast systems which require high security and reliability. Our N-tier architecture significantly reduces workload of the satellite layers especially for bandwidth consumption, computation resources and storage requirements. N-tier approach localizes effects of the rekeying operation (forward-backward security) and provides significant performance gain. Moreover, batch keying and ticketing mechanisms are used which additionally reduce workload of the satellite and terrestrial layers. Also, as a novel approach for cryptographic method, our protocol uses multi-recipient signcryption scheme, which provides confidentiality, authentication, unforgeability and non-repudiation together, more efficiently than classical sign-then-encrypt approaches. As a result, NAMEPS has many advantages for very large, dynamic and security critic satellite multicast systems. © 2006 IEEE.
