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 file encryption transmission method based on a DES 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 communication and automation 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, enable e-file, official document transmits 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.
File 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: file is found in the file address that 1. system is selected according to user.With the summary of MD5 algorithm calculation document, 2. user uses the RSA private key of oneself to sign to the summary info generated and 3. generates a string random code by system, 4. and then adopt chaos algorithm encrypt file to carry out double-encryption 5. to use the PKI of recipient to carry out RsA public key encryption to the random code that previous step generates calculate des encryption key according to random code, utilize encryption key to carry out des encryption 5. together with the summary info after encryption to original document.
After completing cryptographic operation, 5. 4. 3. system can walk generation with the Piece file mergence by the is a complete file, then calls file and sends process and send file.
After file arrives recipient, after file reception completes, system will carry out the decryption oprerations of file automatically.It is corresponding for deciphering with encryption.Concrete steps are as follows: the random code that the public key encryption 1. reading transmit leg use recipient according to the length information read from file is crossed, and the private key searching oneself is decrypted, 2. chaos decode key is calculated by the random code after deciphering, with decruption key, chaos decode is carried out to file and 3. calculate DES decruption key by the random code after deciphering, with decruption key, DES deciphering is carried out to file, 4. from the file after DES deciphering, read out the signature of transmit leg, namely the original document summary info of transmit leg encrypted private key is used, search the PKI of transmit leg and summary info is decrypted, 5. MD5 algorithm is used to calculate the summary info receiving file, the summary info obtained with deciphering compares, if identical, then receive file, if different, then suffered to distort in supporting paper transmitting procedure, notice transmit leg, and abandon the reception of file.
