Abstract
The digital office system brings convenience to a user while causing various safety problems. Concerning many safety hazards, the invention designs and realizes an office network audio frequency digit encryption transmission method based on combination of an MP3 compression algorithm and a chaotic algorithm, which solves the safe problems existing in the current traditional digital office system, compensates defects and shortcomings of the digital office, and enables the digital office to be safe and reliable.
Description
Technical field
The invention belongs to the communications field.
Background technology
At present, China's E-Government has also had a great development in the short time since carrying out " project of government's surfing the net ".Many administrative departments all successively establish external site for service.The application of electronic government affairs system can improve office efficiency, alleviate the work load of staff, save valuable office funds, improve traditional idea in management and management mode, improve the quality of government functionary and staff, realize that office is with no paper, resource informationization and the scientification of decision-making.
In electronic system, often can carry out various long-distance video or audio conferencing, for enabling audio-frequency information transmit safely, reliably, rapidly, adapting to the demand of current information networking, e-cooperative work, is problem demanding prompt solution.The opening of network brings very large facility to our work, also brings very large potential safety hazard to us simultaneously.
Audio encryption transmission and management system addresses that need just, the safeguard protection of the information that realizes in network system, transfer management and automatic monitoring, meets the demand of information networking, e-cooperative work between this department and other department, between our unit inside.
Summary of the invention
System can be encrypted operation to needing the file passed, and the concrete steps of encryption are as follows: 1. Choice encryption is to the Frame of security-sensitive, and 2. Frame is by MP3 compression algorithm 4. and then adopt chaos algorithm scrambled data frame to select sensitive parameter type.
After Frame arrives recipient, system will carry out the decryption oprerations of Frame automatically.Concrete steps are as follows: 1. from Frame, read random code calculate chaos decode key according to the length information read, and carry out chaos decode 3. calculate MP3 data by the random code after deciphering and 4. from MP3 Frame, restore initial data with decruption key to file.
Claims (1)
- The digital encryption of the audio frequency that 1.MP3 compression algorithm and chaos algorithm combine transmits.
