Multicast communication demands scalable security solutions for group communication infrastructure. Secure multicast is one such solution that achieves the efficiency of multicast data delivery. Key generation plays an important role in enforcing secure and efficient key distribution. This chapter addresses the issues focused on the area of key generation on key management cryptographic algorithms that support security requirements in multicast group communications. These issues are of importance to application developers wishing to implement security services for their multicast applications. The three main classes, centralized, decentralized, and distributed architectures, are investigated and analyzed here and an insight given to their features and goals. The area of group key generation is then surveyed and proposed solutions are classified according to the efficiency of the cryptographic algorithms and multicast security requirements. We also outline the open problems in this area.

Target Environment

With the rapid growth in mobile commerce (m-commerce) applications, the need for providing suitable infrastructure to support these applications has become critical. Secure multicast is a key element of this infrastructure, in particular, to support group m-commerce applications such as mobile auctions, product recommendation systems, and financial services. Despite considerable attention to m-commerce security, most existing security solutions focus on unicast communications. On the other hand, numerous solutions for secure multicast exist that are not specifically designed with m-commerce as a target environment. Clearly, to address secure multicast in m-commerce, we must start by forming a comprehensive picture of the different facets of the problem and its solutions. In this chapter, we identify system parameters and subsequent security requirements for secure multicast in m-commerce. Attacks on m-commerce environments may undermine satisfying these security requirements resulting, at most times, in major losses. We present a taxonomy of common attacks and identify core services needed to mitigate these attacks and provide efficient solutions for secure multicast in m-commerce. Among these services, authentication and key management play a major role. Given the varying requirements of m-commerce applications and the large number of current key management schemes, we provide a taxonomy and a set of performance metrics to aid m-commerce system designers in the evaluation and selection of key management schemes.

Data sharing is increasingly important for many users and sometimes an essential requirement, especially for industries and society’s used to gain proceeds. Sharing group resource among cloud users is a major problem, still the data privacy leak. The existing system Group Key Management method used for sharing Key Generation and distribution in the group member or users. Sometimes change to user one group to another group, the group key to enable authenticated users to access the files securely and efficiently is still a challenging problem. This problem to avoid that sharing data in group using the Time Based Group Key Management (TGKM) techniques for cryptographic cloud storage application , which Conditional Identity Based Broadcast Proxy Re-Encryption (CIBPRE) used to transforming the data’s(files) major process in cloud server. To Key Generation method for user a time based dynamic group Key which capably to make stronger in cloud security. Generally, security and performance evaluated that the proposed scheme is highly efficient and satisfies the security requirements for cloud based application.
