ABSTRACT

The Internet of Things (IoT) completes the direct integration of computing systems with the physical world .It reduces costs for manual, and it improves efficiency while facilitating people's lives, and brings enormous economic benefits. However, with the increasingly deep integration of the Internet of Things with people's production and life, some characteristics of the Internet of Things itself also pose a huge threat to security and privacy. Cryptographic technology is the core of information security, and the key is the basis to ensure the security of cryptographic technology. Therefore, it is very important to establish a suitable and perfect key management system in the environment of the Internet of Things. Starting from the characteristics of the Internet of Things, this paper analyses the requirements of these characteristics for key management. The three main key management systems in the Internet environment, Public Key Infrastructure, Combined Public Key and Identity-based Cryptograph, are introduced and discussed. The advantages and disadvantages of these key management systems in the Internet of Things environment are discussed and compared from three aspects.
