The Internet of Things makes it possible to exchange information between people, things and things, people and things, and makes information security more and more important. However, there are few standards in the field of information security of the Internet of Things. Therefore, based on the characteristics and application requirements of the Internet of Things environment, this paper optimizes the Advanced Encryption Standard (AES) and builds the data encryption standard DESI(Data Encryption Standard in IoT) in the Internet of Things environment.. The analysis shows that DESI has better security and is therefore suitable for encrypting data in the IoT environment. Keywords: Internet of Things, encryption standard, AES, DESI, information security.
