MABS

ABSTRACT

MABS Stands for Multicast Authentication Based on Batch Signature. 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. We also present an enhanced scheme MABS-E, which combines the basic scheme with a packet filtering mechanism to alleviate the DoS impact while preserving the perfect resilience to packet loss.

Traditionally, multicast authentication schemes manage the different involvement of the receivers by letting the sender. Choose the block size, divide a multicast stream into blocks, connect each block with a signature, and spread the effect of the Signature across all the packets in the block. The correlation among packets makes them vulnerable to packet loss. Moreover, the lack of Denial of Service occurred. Furthermore in the existing system the efficiency of the receivers or not considered. Compared with the multicast sender, which could be a powerful server, but receiver are having different capabilities and resources.

Our Goal is to eliminate the correlation among packets and provide the perfect resilience to packet loss. We develop a efficient system by using latency, computation, and communication overhead due to an efficient cryptographic primitive called batch signature, which supports the authentication of any number of packets simultaneously.

We also present another scheme called packet filtering mechanism to alleviate the DoS impact while preserving the perfect resilience to packet loss. It is gaining popular applications such as real-time stock quotes, interactive games, video conference, live video broadcast, or video on demand.

SYSTEM ANALYSIS

Existing System:

          Traditionally, multicast authentication schemes manage the different involvement of the receivers by letting the sender. Choose the block size, divide a multicast stream into blocks, connect each block with a signature, and spread the effect of the Signature across all the packets in the block. The correlation among packets makes them vulnerable to packet loss. Moreover, the lack of Denial of Service occurred. Furthermore in the existing system the efficiency of the receivers or not considered. Compared with the multicast sender, which could be a powerful server, but receiver are having different capabilities and resources.

Proposed System:

          Our Goal is to eliminate the correlation among packets and provide the perfect resilience to packet loss. We develop a efficient system by using latency, computation, and communication overhead due to an efficient cryptographic primitive called batch signature, which supports the authentication of any number of packets simultaneously.
