基于密钥联系表的无线传感器网络密钥管理方案

New key management scheme of wireless sensor networks based on key relation table

考虑到多播密钥管理必须满足前向私密性、后向私密性、抗同谋破解、可扩展性以及健壮性等安全需求,同时针对于无线传感器网络能源受限的特点,提出了一种新的基于门限机制和密钥联系表的密钥管理方案。通过把密钥映射于空间曲线和曲面上,该方案在小幅度增加计算复杂性的同时,对通信复杂性和存储复杂性进行了较大的优化。

Aimed at some security properties on key management for multicast such as forward confidentiality, backward confidentiality, resisting conspiracy-analysis, expansibility and robustness, and furthermore the obvious character of energy-constraint, a new key management scheme based on threshold mechanism ＆ key relation table was proposed, which mapped keys＇ value onto the three-dimensional curves and surfaces. Although computing complexity increases within a little scale, the performance optimization of memory complexity as well as communication complexity were proposed.
