Problems solved by technology

[0004] (1) The general authentication architecture of traditional IoT devices requires two-factor authentication, which is a challenge to the limited battery capacity of the terminal; there is no flexibility in key update, and each key update requires multi-layer key update.
[0005] (2) PUF-based secure communication protocol, its architecture is poorly compatible with existing standards and needs a lot of customization
[0006] (3) At present, most IoT devices in the field of power industry control rely on various power control equipment manufacturers, and cross-manufacturer and cross-platform security certification and end-to-end security research based on national secret algorithms are still blank fields

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Narrowband IoT has broad application prospects in smart grid production management, asset lifecycle management, and smart power consumption. Its own characteristics and application field security requirements pose challenges to power business data security; existing technologies require double AKA Authentication, poor compatibility with network architecture. The NB-IoT end-to-end security scheme of the power grid based on the physical unclonable function and the national secret algorithm SM3 of the present invention has the characteristics of small communication overhead, light weight and flexible update, and can be ...

Abstract

The invention belongs to the technical field of end-to-end communication, and discloses a power grid NB-IoT end-to-end data processing method based on a physical unclonable function. At the initialization stage, the enterprise application server generates a CSP of the PUF embedded in the NB-IoT module and stores the CSP in a user database of the service platform; A reasonable CSP number n is set,an international mobile user identifier, an international mobile device identification code and a subordinated EAS identity of the NB-IoT module are obtained, and an NB-IoT identity ID with a servicebinding relation is obtained through calculation of an SM3 algorithm; And the MME pushes the CK and the IK to the HSE, and a secure channel between the KE2Menc, the KE2Mint, the KIntermediate, the HSSand the HSE is calculated and is guaranteed by a network domain security mechanism. Compared with the prior art, the method has the characteristics of light weight and flexible updating, and the security of the service system is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of end-to-end communication, and in particular relates to an end-to-end data processing method of a power grid NB-IoT based on a physical unclonable function. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: with the rapid development of information and control technology, my country has begun to vigorously promote the "big cloud" The fusion application of information technology, automatic control technology and artificial intelligence technology in power grid. The digitization, informatization, and interaction of smart grids require state monitoring of grid facilities, including power production management, life cycle management of power assets, and smart power consumption. Narrow Band Internet of Things (NB-IoT) provides an effective technical approach to meet the needs of smart grids. In June 2017, the Ministry of Industry and Information T...
