Abstract

In order to improve the security of information transmitted in the internet of things, this study designs an information security system architecture of internet of things based on a lightweight cryptography. In this security system, an authentication protocol, encryption/decryption protocol and signature verification protocol are proposed and implemented. All these security protocol are used to verify the legality of access device and to protect the confidentiality and integrity of transformation data. This study analyzes the security and performance of the system.

Keywords:
