Problems solved by technology

[0002] The existing MAAKA scheme uses pseudo-random identity to achieve user anonymity, but fails to achieve anonymity and untraceability at the same time. In the MAAKA scheme, the public key algorithm is used to avoid offline dictionary attacks on sensor nodes, but for sensor nodes, the public The calculation overhead and energy consumption of the key algorithm are too large, so it is urgently needed for those skilled in the art to solve the corresponding technical problems

Abstract

The invention provides a pseudonym-based anonymous authentication and key negotiation optimization method and optimized authentication analysis method for the Internet of Things. The method comprises the following steps: S1, a user and a sensor node separately register a gateway node, and for the difference of the user and the sensor node, a user registration protocol and a sensor node registration protocol different from each other are adopted; and S2, after the registration, the user logs in the system through a user login protocol and an authentication and key negotiation protocol, and under the assistance of the gateway node, the sensor node requiring access realizes mutual authentication and a negotiation shared session key. By adoption of the method provided by the invention, better anonymity, non-traceability and security are realized.

Description

technical field [0001] The invention relates to the field of computer security authentication, in particular to an pseudonym-based anonymous authentication and key agreement optimization authentication method and an optimization authentication analysis method for the Internet of Things. Background technique [0002] The existing MAAKA scheme uses pseudo-random identity to achieve user anonymity, but fails to achieve anonymity and untraceability at the same time. In the MAAKA scheme, the public key algorithm is used to avoid offline dictionary attacks on sensor nodes, but for sensor nodes, the public The calculation overhead and energy consumption of the key algorithm are too large, so it is urgently needed for those skilled in the art to solve the corresponding technical problems. Contents of the invention [0003] The present invention aims to at least solve the technical problems existing in the prior art, and particularly innovatively proposes an anonymous authenticatio...
