Scalable cryptographic scheme for networked multimedia applications

Computer security has become the main stream issue to protect the sensitive information in open networks. The complete secure system is hard to design these days due to vulnerabilities in firewalls, file and application servers, email servers, and Web servers. The solution to problems of computer security and privacy can be achieved by the cryptography mechanism. A popular way to implement security protocols uses a combination of several cryptographic schemes to overcome various limitations of security primitives. The design of scalable security protocols that are interrelated with a single cryptosystem for multimedia is a challenging cryptographic technology in the cryptologic research community. We propose the scalable cryptographic scheme for security services. The proposed eigen-based security primitives solves a wide range of secrecy, non-repudiation, authenticity, and integrity problems in many security aware multimedia applications. The new cryptography technology may play an important role in the trusted network interpretation environments.
