Adaptive secured multicast key management with re-keying process

Data integrity is given top priority when exchange of information takes place. Information loses value, even becomes redundant should the intended user fail to obtain it. Modern day communications are mostly done on World Wide Web (WWW). Group communication must strike a balance between how quickly data is exchanged among users, at the same time, data security must not be compromised. Hence, protocols are in place to ensure data security in a cryptographic group by encrypting data before sending it to users. A separate transaction takes place with a key to decrypt the data. As the users grow in numbers, the key management becomes harder and complex in nature. Herein, Logical Key Hierarchy (LKH) has been proposed for a cryptographic group. A thorough analysis of the prevailing key management systems has been conducted. Few surveys have been researched and analyzed. Fundament security systems have been tested in real-life settings. A key management system needs to be in place that sharpens data security but provides users with quick service. Group Secure Association Key Management Protocol (GSAKMP) has been widely used. But online transaction and group that are geographically spread pose a different challenge. Hence, a proposal has been adopted to manage keying and rekeying for the members of a cryptographic group.
