Embodiment Construction

[0037] Such as figure 1 As shown, a virtual reality system for an information security environment includes:

[0038] An environmental information collection unit, used to collect input voice signals and action signals;

[0039] A voice information security unit, configured to encrypt the voice signal;

[0040] An action information security unit, configured to encrypt the action signal;

[0041] The virtual reality voice signal transmission unit is used to transmit the encrypted voice signal and action signal to the virtual reality environment.

[0042] Preferably, the voice information security unit encrypts the above-mentioned voice signal in the following manner: set N initial signals s 1 (t),...,s n (t) and M key signals k 1 (t),...,k M (t), the encryption formula is:

[0043] X(t)=[x 1 (t),...,x N (t)] T =As k (t)

[0044] Among them, X(t) represents N encrypted signals, s k (t)=[s 1 (t),...,s n (t),k M (t)] T , A is an encrypted matrix of N×(M+N), and e...

Abstract

The invention provides a virtual reality system of an information security environment, and further provides a decryption algorithm of the virtual reality system. Denoising processing on voice signalnoise is achieved in the encryption and decryption process, and the defect that a traditional encryption algorithm cannot ensure the information security and the defect existing when a chaotic systemconducts encryption are overcome to a certain extent.

Description

technical field [0001] The invention belongs to the field of voice signal processing, and in particular relates to a virtual reality system for an information security environment. Background technique [0002] With the global rise of network technology and the development of digital signal processing technology, voice communication technology has achieved breakthrough development and wider application. However, when the voice communication content involves personal privacy, business secrets and state secrets, people will consider the confidentiality of voice information transmission. At the same time, when performing voice communication in an actual environment, the two parties in the call are easily disturbed by the background noise of the surrounding environment, thereby affecting the effect of communication. Therefore, it is very important to study voice encryption and noise reduction to ensure the security and quality of voice communication. [0003] Voice encryption ...
