Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] refer to Figure 1 to Figure 8 , a chaotic message authentication code implementation method for wireless sensor networks, the chaotic message authentication code implementation method includes the following steps:

[0041] 1) First, the Logistic chaotic mapping function based on integer calculation is used for wireless sensor nodes. The iterative formula of the Logistic chaotic mapping function is:

[0042] z n + 1 = z n 2 - z n 2 > > 6 - 1 - - - ( I - 10 )

[0043]Among them, z n =ax n +a, tak...

Abstract

The invention relates to a chaos message authentication code realization method for a radio sensor network, which comprises the following steps: 1) firstly, adopting a Logistic chaotic mapping function calculated based on an integer type for a radio sensor node; 2) adopting a block encryption algorithm which has the dynamic Feistel structural characteristic and has a block length being 8 bits only; and 3) realizing a message authentication code of which the length is 32 bits based on the block encryption algorithm. The invention provides the chaos message authentication code realization method for the radio sensor network, which has the advantages of good safety and higher efficiency.

Description

technical field [0001] The invention relates to a method for realizing a chaotic message authentication code. Background technique [0002] The message authentication code is the Hash value of the message, and the key is the design of the Hash function. Hash function, also called hash function, is a special one-way function that can compress messages of any length into fixed-length message digests. At present, the common traditional Hash functions mainly include MD4, MD5, SHA1, etc. [0003] Because the iterative process of the digital chaotic system is not only sensitive to the initial conditions, but also has the property of a one-way function in a certain sense, so there have been many researches on chaotic Hash, including the construction method of one-way Hash function based on variable parameters. , in the process of chaotic iteration, this method uses the last iteration value and the currently processed plaintext message to continuously adjust the control parameters ...
