Secure mutual authentication and key agreement protocol under Internet of Things environment

Abstract

The invention discloses a secure mutual authentication and key agreement protocol under the Internet of Things environment. The secure mutual authentication and key agreement protocol comprises the following steps: step A, a registration phase: submitting own ID information to a server S by a user Ui, and registering to become a legal user; and step B, a login and authentication phase: performing two-way identity authentication and key agreement by the registered user Ui and the server S, and establishing a session key for the communication. The secure mutual authentication and key agreement protocol under the Internet of Things environment provided by the invention solves the unsafe problems of information leakage and stealing of the two communication parties in the Internet of Things communication, and has higher performance and efficiency in the similar security protocols. The invention adopts an elliptic curve cryptography algorithm, and realizes key negotiation and establishment with low consumption and high security on devices such as embedded devices and so on with limited computing power and storage resources.

Description

technical field [0001] The invention relates to a two-way authentication and key agreement agreement between a communication device and a server under the Internet of Things environment. Background technique [0002] With the vigorous development of the Internet of Things, more and more communication devices are connected to the network through wired or wireless methods to realize information exchange and resource sharing. However, these transmitted data are easily hijacked and tampered with by attackers. Once a security leak occurs, sensitive information such as user privacy cannot be guaranteed, which will cause great or even immeasurable losses to users. Therefore, information security in the Internet of Things environment has become an urgent need for people, and it is also a guarantee for the normal operation of almost all communications. [0003] Currently, embedded devices, wearable sensors, and RFID devices are widely used in fields such as healthcare, smart home, ...

AI Technical Summary

Problems solved by technology

[0006] So far, a large number of ECC-based authentication and key agreement protocols are based on passwords. Although these protocols protect information security, their efficiency is not high.

In addition, because the passwords used by users are often too simple, such as "123", "abc", etc., they are vulnerable to dictionary attacks
