specific Embodiment approach 1

[0029] Specific implementation mode 1. Combination Figure 1 to Figure 5 Describe this embodiment, based on the space network cross-domain anonymous identity authentication method of hyperchaotic encryption, the method is realized by the following steps:

[0030] Registration stage:

[0031] a1. The communication node in the space network first needs to register with the authentication center in the trusted domain where the communication node is located. combine figure 1 and image 3 , the communication node Ga in the spatial trusted domain SDa sends the ID information S_id of the node to the local security authentication center ISa in the trusted domain SDa where the Ga node is located through a secure channel.

[0032] a2. The local security authentication center ISa generates temporary ID information TS_id for the Ga communication node.

[0033] a3. The local security authentication center ISa calculates and generates the local key key_x and the local authentication inf...

Abstract

The invention provides a space network cross-domain anonymous identity authentication method based on hyper-chaos encryption, relates to the technology of space information network, and solves the problem that the security mechanism applied in the conventional network cannot be directly applied to space network, and space cross-domain identity authentication cannot be realized. Provided is a space network cross-domain anonymous identity authentication method based on hyper-chaos encryption. The method includes two parts: a register stage and an authentication stage, a chaos algorithm is sensitive to initial conditions and control parameters, the structure is complex, prediction and analysis are difficult, and pseudo random sequences with good randomness and complexity are provided so that the chaos is applicable to encryption. A quantum cellular neural network is a cellular neural network structure coupling via quantum cellular neural network automata, complex linear dynamic features are obtained from the polarizability and quantum phase of each quantum cellular automaton, a nano-scale hyper-chaos oscillator can be constructed, the power consumption is low, the integration level is high, and the application requirement of space network satellite nodes can be better met.

Description

technical field [0001] The invention relates to space information network technology, in particular to a space network cross-domain anonymous identity authentication method based on quantum cell neural network hyperchaotic system encryption. Background technique [0002] The integrated information network of space and earth refers to satellites operating in different orbits, of different types and of different performances. Through inter-satellite and satellite-to-ground links, various communication platforms on the ground, ocean and deep space are intensively combined to form a global coverage of communication, navigation, and navigation. , a comprehensive and efficient integrated information network for information support and security. With the rapid progress of the global integration process, people's dependence on network communication technology is becoming more and more obvious. The rapid development of the integrated network of heaven and earth will bring various co...
