The Research of Security Network Group Key Management

Abstract:

To improve the security and applicable capability of the group key management in 802.16e standard, the traditional group key management mechanism is discussed and the current security owing to lack of considering comprehensive factors, some security solutions designed also bring some problems. To solve these issues, Current multi-hop Wimax group key management security solutions were described firstly, then One-way Function Tree group key management mechanism is analyzed; An efficient group key management scheme based on one-way function is proposed, which can be used in multi-hop Wimax network system to enhance the security of group management effectively. Analysis result shows that, compared with the methods of One-way Function Tree, he proposed scheme has better performance in key storage, key updating and key calculation cost, which provides an effective solution for group key management in Wimax network and has better application value.
