A chaos-based computer random number generation system and method

Abstract

The invention discloses a chaos-based computer random number generation system and method, which improves the pseudo-random number generation function commonly used in computer systems. The method includes three interfaces: hdintrand function, hddoublerand function and hdcharrand function, which respectively realize the generation of integer pseudo-random numbers, floating-point pseudo-random numbers and character-type pseudo-random sequences. This method adopts the random number generation method based on the improved one-dimensional Logistic chaotic map. Compared with the random number generation based on the congruence formula, it has security in the sense of cryptography and can meet the random number requirements in information security occasions. The required random number is obtained by specifying the type and range of the interface, and the function of retrieving the random number by the key is provided to maintain the randomness and efficiency of the random number generation function of the original computer system, and at the same time, the improvement of security and versatility makes it possible It has higher practical value.

Description

technical field [0001] The invention relates to the field of information security, in particular to a chaos-based computer random number generation system and method. Background technique [0002] Pseudo-random number generator (PRNG) is widely used in various fields such as system simulation and security. Based on a reliable and efficient pseudo-random number generator, the operation, evolution and development process of the system are truly described in the system simulation. In the field of information security based on cryptography, pseudo-random number generators also play an important role. Key generation, digital signatures, authentication and authentication, and various secure communication protocols are inseparable from high-quality random numbers. In a sense, the security of random numbers determines the security of the entire security system. There are four commonly used pseudo-random number generation functions in C language <stdlib.h>: rand(), srand(), r...
