Abstract

The invention discloses a secure Internet of Things network access device, Internet of Things terminal equipment and an Internet of Things system, and relates to the technical field of Internet of Things security. The secure access device comprises a secure chip and a first communication module and a second communication module which are connected with the secure chip; the first communication module is used for establishing connection between the Internet of Things terminal equipment and the secure chip; the second communication module is used for establishing connection between an Internet of Things server and the secure chip; and the secure chip is used for receiving plaintext data sent by the Internet of Things terminal equipment through the first communication module, encrypting the received plaintext data and then sending the encrypted plaintext data to the Internet of Things server through the second communication module and further used for receiving ciphertext data sent by the Internet of Things server through the second communication module, decrypting the received ciphertext data and then sending the decrypted ciphertext data to the Internet of Things terminal equipment through the first communication module. Compared with the prior art, the secure access device has the advantage that the network access security of the Internet of Things terminal equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things security, in particular to an Internet of Things network security access device, and an Internet of Things terminal device and an Internet of Things system based on the access device. Background technique [0002] With the rapid popularization and development of the Internet and the Internet of Things, today's network is filled with a wide variety of IoT smart terminal devices without security guarantees, such as network cameras and related terminal devices in the smart home field. In the face of the rapid growth of the number of smart terminal devices in the Internet of Things, the long-term lack of security mechanisms will become a bigger problem. [0003] SSL (Secure Sockets Layer, Secure Sockets Layer) and its successor TLS (TransportLayer Security, Transport Layer Security) is a security protocol that provides security and data integrity for network communications, to ensure the se...
