Management Algorithm and Design for Internet of Things Key under the Low Data Environment

为了提高低数据量环境下物联网密钥的安全性与可靠性,需要对低数据量环境下物联网密钥管理算法以及密钥管理方案进行设计研究;使用当前管理算法对低数据量环境下物联网密钥进行管理时,在物联网网络节点增加到一定数量的情况下,无法保证低数据环境下物联网的安全性与可靠性;为此,提出一种基于LHKE的低数据量环境物联网密钥管理算法与方案设计方法;该算法是由当前算法为基础结合Qoskm算法优点形成的一种新的低数据量环境下物联网密钥算法,此算法将设立两个相同的低数据量密钥树,通过计算组播成员在物联网上的信任度与安全度,将信任度与安全度较高的组播成员放在一棵低数据量密钥树上,其他的组播成员放在另一棵低数据量密钥树上,再通过LHKE算法的初始化、子密钥生成和网络密钥生成3个阶段,对低数据量环境下物联网密钥进行管理;实验仿真证明,所提算法提高了低数据量环境下物联网密钥的安全性与可靠性。

In order to improve the safety and reliability of the low amount of data under the environment of the IOT key,the need for low amount of data under the environment of internet key management algorithm and key management scheme was designed.Using the current management algorithm of low amount of data under the environment of internet key management,increase to a certain number of network nodes in the Internet of things next,can not guarantee the safety and reliability of low data under the environment of the Internet of things.Therefore,put forward a method of network key management algorithm and scheme design of low amount of data environment based on LHKE.The algorithm is a low amount of data the new ring is formed by the current algorithm based Qoskm algorithm Under the environment of the IOT key algorithm,the same two low amount of data will be set up in the key tree algorithm,through the calculation of multicast members in the Internet of things on trust and security,the members of multicast degree and safety high degree of trust on a low amount of data on the key tree,the other members in the multicast another low amount of data on the key tree,and then through the LHKE algorithm initialization,key generation and key generation network in three stages,the low amount of data under the environment of internet key management.The experiments show that the proposed algorithm improves the safety and reliability of the low amount of data under the environment of IOT key.
