키 관리시스템의 부하절감을 위한 향상된 키 분배 메커니즘과 보안프로토콜

다국어 초록 (Multilingual Abstract)

In an Ubiquitous Environment, the growth of various services and equipment is forecasted to increase both the multicast users and diverse hacking attacks of the multicast key. Rapid increasing of multicast users and application security protocols reduce the performance of the Central key management system. Accordingly, We propose to elevate the functionality of the key management mechanism for greater efficiency and stability of the multicast services, in this paper. The existing key management mechanism comparison and simulation will analyze these problems. We propose the advanced SMKD (Secure Multicast Key Distribution) mechanism application of the small group and key length control, new security protocol by methods to solve these problems. The SMKD Model in this paper will help reduce loading the key distribution and encryption execution of a central key management system, and this model can also ensure stability to a central key management system by efficient key management.
