Method for realizing equipment authentication, data integrity and secrecy transmission for Internet of Things

Abstract

The invention relates to a method for realizing equipment authentication, data integrity and secrecy transmission for Internet of Things (IoT), which is characterized in that the information collected by a sensor is transmitted to a network data center after being subject to digital signature and encryption through an intelligent chip; the network date center obtains the complete and believable information collected by the sensor by utilizing an authentication center (AC) to carry out data deciphering and signature verification; the network data center transmits an operational order to a sensor terminal, the operational order is subject to the digital signature and the encryption by the AC and then transmits to the sensor; the sensor obtains a correct and complete operational order after operational order data obtained by the sensor is subject to the data deciphering and the signature verification through the intelligent chip; and an equipment authentication protocol of the AC to the sensor is used to determine whether the sensor equipment is confirmed to be in a normal operation state or not, thus an information safety system for the infrastructure authentication, the data integrity and the secrecy transmission of the IoT is established.

Description

Technical field: [0001] The invention relates to the field of Internet of Things information security. Background technique: [0002] At present, there are no information security products at home and abroad that can solve the Internet of Things from the perception layer, the transport layer to the application layer. Cryptographic algorithm and symmetric cryptographic algorithm are used together to establish user identity authentication, file digital signature and data confidentiality transmission system. However, the authentication speed of PKI / CA is too slow, and the number of users managed by a single CA authentication center is insufficient, so many CA authentication centers need to be established The establishment cost is too high, and other user identity authentication, file digital signature and data confidentiality transmission systems based on combined symmetric key technology cannot be directly used for information security of the Internet of Things. In short, exis...

[0002] At present, there are no information security products at home and abroad that can solve the Internet of Things from the perception layer, the transport layer to the application layer. Cryptographic algorithm and symmetric cryptographic algorithm are used together to establish user identity authentication, file digital signature and data confidentiality transmission system. However, the authentication speed of PKI / CA is too slow, and the number of users managed by a single CA authentication center is insufficient, so many CA authentication centers need to be established The establishment cost is too high, and other user identity authentication, file digital signature and data confidentiality transmission systems based on combined symmetric key technology cannot be directly used for information security of the Internet of Things. In short, existing authentication and digital signature products None of them can meet the market's demand for information security in the Internet of Things
