specific Embodiment approach

[0043] refer to Figure 1-Figure 3 , the specific embodiments of the present invention are as follows:

[0044] 1. In the most initial situation, each element under the IoT system is initialized. First, generate basic system parameters through a trusted third-party T gateway node, including selecting the group E on the elliptic curve p (a, b), (a, b represent two random numbers on the finite field, p, q are two large prime numbers on the elliptic curve), select three hash functions h, H, H 1 :h,H,H 1 →{0,1} * , choose the message authentication code MAC function and choose the bilinear pair e; choose the random number As the master key of the trusted third party, Represents a set of positive integers, and calculates the system public key Q T =s T P (P is the generator of the group); subsequently, the trusted third party T announces the public parameter set:

[0045] parameters={a,b,p,q,P,Q T ,h,H,H 1 ,MAC,e};

[0046] In addition, the sensor node SN chooses a rand...

Abstract

The invention provides an IoT (Internet of Things)-oriented user authentication and key negotiation system and method, and relates to the field of IoT. The system comprises a system initializing module, a key generation module and an authentication and key negotiation module, wherein the system initializing module is used for initializing an IoT system, gateway nodes, users and sensor nodes; the key generation module is used for finishing the generation of keys for participants of the system in the IoT; and the authentication and key negotiation module is used for finishing mutual authentication between a user and a server and negotiating a common session key during access to remote sensor node information. The system has the characteristics of connectivity, forward-backward safety, non-connectivity of sessions, anonymity and the like, and the requirements of the IoT are met well on the aspects of safety performance and computing cost.

Description

technical field [0001] The invention belongs to the communication field of the Internet of Things, in particular to a security authentication method for communication between users and sensor nodes in the Internet of Things environment. Background technique [0002] The Internet of Things (IoT) is a huge thing-thing connected network, which can identify, control and centrally manage various things around us through sensors, embedded devices, etc. It opens up a new opportunity for people to connect to sensor devices distributed around them to obtain information. Users can access services provided by smart device applications anywhere and at any time in the Internet of Things. With the development of network technology, many IoT applications are also designed, such as medical services, smart grid devices, smart transportation systems and smart energy, etc., which greatly improve our living conditions. However, the privacy and security of the Internet of Things are also impor...
