Comparison analysis in Multicast Authentication based on Batch Signature (MABS) in Network Security
This addresses security issues in network environments like the Internet and wireless networks for multicast communication, but it appears incremental as it builds on existing batch signature methods.
The paper tackles the problem of packet loss vulnerability and lack of Denial of Service resilience in conventional multicast authentication schemes by proposing MABS, a novel protocol that eliminates packet correlation and provides perfect resilience to packet loss, with efficient performance in latency, computation, and communication overhead.
Conventional block-based multicast authentication schemes overlook the heterogeneity of receivers by letting the sender choose the block size, divide a multicast stream into blocks, associate each block with a signature, and spread the effect of the signature across all the packets in the block through hash graphs or coding algorithms. The correlation among packets makes them vulnerable to packet loss, which is inherent in the Internet and wireless networks. Moreover, the lack of Denial of Service (DoS) resilience renders most of them vulnerable to packet injection in hostile environments. In this paper, we propose a novel multicast authentication protocol, namely MABS, including two schemes. The basic scheme (MABS-B) eliminates the correlation among packets and thus provides the perfect resilience to packet loss, and it is also efficient in terms of latency, computation, and communication overhead due to an efficient cryptographic primitive called batch signature, which supports the authentication of any number of packets simultaneously.so we discuss their comparisons and performance evaluation of Packet Loss, Comparisons over Lossy Channels, Comparisons of Signature Schemes, computationational overheads etc.
