摘要

目前智能家居系统的数据加密技术多采用对称加密方式，但是这种方式存在密钥管理的问题，为实现密钥的安全，智能家居系统采用非对称加密技术，在此基础上设计了基于椭圆曲线密码体制（ECC）的密钥管理机制来达到保障密钥安全的目的。本密钥管理机制包括基于ECC的数据加密密钥管理机制和基于ECC的数字签名密钥管理机制，它们可以使得无线网络节点在身份认证，密钥的产生、分发、存储、更新等环节中密钥的安全性得到保障，其中密钥的存储环节利用了芯片内部闪存的读保护机制，实现了硬件级别的安全存储。最后对本机制的安全性、耗时和可扩展性进行了分析，结果表明该机制具有较强的安全性和可扩展性，在耗时方面优于E-G密钥管理方案。

Abstract

At present

the data encryption technology of smart home system uses symmetric encryption method

but there is a problem with key management in this way.To achieve the security of the key

the smart home system uses asymmetric encryption technology.On this basis

the key management mechanism based on ECC was designed to achieve the purpose of guaranteeing key security.The key management mechanism includes an ECC-based data encryption key management mechanism and an ECC-based digital signature key management mechanism.So that the wireless network node in the identity authentication

the key generation

distribution

storage

update and other aspects of the key security were guaranteed.Finally

the security

time-consuming and scalability of this mechanism were analyzed.The results show that the mechanism has strong security and expansibility

and it is superior to E-G key management scheme in time-consuming.
