The invention relates to a device for generating a random number by using chaos theory, which comprises a password generating module, an iteration calculating module, a random number output processing module and an iteration calculating control module, wherein the password generating module is used for generating an initial password and transmitting the initial password to the iteration calculating module; the iteration calculating module is used for performing iteration calculation on an iteration target transmitted by an iteration calculating control module, thus obtaining the random number; the random number output processing module is used for changing and outputting the random number according to the set; and the iteration calculating control module is connected with the output of the iteration calculating module and used for providing a target for iteration calculation in calculation of the iteration calculating module. The invention further discloses a dynamic password token for using the device. The application of the device for generating random number by using chaos theory and the dynamic password token has the benefits of low cost and high speed and stability.
Description
technical field [0001] The invention relates to the field of data encryption, more specifically, to a device for generating random numbers using the principle of chaos and an OTP token thereof. Background technique [0002] With the continuous development of information technology (IT), data security requirements are getting higher and higher, and data encryption calculation has important application significance in many fields such as data transmission and data storage. The data before being encrypted is called "plaintext", the data after encryption is called "ciphertext", and the password used for encryption calculation and decryption calculation is called "key". Encryption is to change the original information data with a special algorithm, so that even if unauthorized users obtain the encrypted information, they still cannot understand the content of the information because they do not know the decryption method. Encrypting data prevents it from being viewed or modified...
