Embodiment Construction

[0047] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0048] see Figure 2 to Figure 4 As shown, the method for performing local authentication of mobile equipment in the third generation mobile communication system includes the following steps:

[0049] (1) Establish a part of the observable Markov decision process system model according to the local authentication process, and determine the information state space of the system model and the information state of the system at each discrete time point, including the following steps:

[0050] (a) Determine the information state π of the system model according to the following formula n :

[0051] π n (i)=P(ξ n =i|Y(n)), i=1, 2,..., N,

[0052] π n (1)+π n (2)+...+π n (N)=1,0≤π n (i)≤1,

[0053] Among them, n is the time point, ξ n is the state of the mobile device at time point n, i is a vector in the state space {1, 2, ..., N}, N is ...

Abstract

The invention relates to a method for performing mobile equipment local authentication in a third-generation mobile communication system, which comprises the following steps: building a partially observable Markovian decision process system model and determining information state space and information states at all discrete time points; building an accumulated cost model and calculating a mappingrelationship between the information states and an optimal local authentication policy; obtaining the optimal local authentication policy based on historical information and scheduling to perform thenext time of authentication; observing result information on the next time point; and updating a system information state and judging authentication result accordingly. The method for performing the mobile equipment local authentication in the third-generation mobile communication system optimizes system performance, satisfies the demands of clients having high requirements on the safety of mobile equipment, optimally determines whether to perform a local authentication process, saves system resources and system operation cost, has stable and reliable operation performance and wide application range, and lays a firm foundation for the further development of information safety technology of the mobile equipment.

Description

technical field [0001] The present invention relates to the field of mobile communication system information security, in particular to the technical field of mobile equipment information security management in the mobile communication system, and specifically refers to a method for performing local authentication of mobile equipment in the third generation mobile communication system. Background technique [0002] Authentication is used to identify the identity of the user, and one or more identification methods can be used: such as passwords, tokens, and user biometrics. Biometrics are divided into static biometrics and dynamic biometrics, such as fingerprints, retina, etc. It belongs to static biological characteristics, while facial expressions, body movements, etc. belong to dynamic biological characteristics. Password authentication is relatively simple and easy to use. Since there is no direct relationship between the password and the user itself, it cannot be sure th...
