Abstract

The invention relates to a remote-control-unit-based encrypting and decrypting method and device. The method includes starting a computer operation system, detecting whether an infrared request instruction, for encrypting or decrypting an important file, sent by a remote control unit is received or not by an encrypting and decrypting control program module, if yes, judging a storage position of the file needed to be encrypted or decrypted in a computer according to the received infrared request instruction by the encrypting and decrypting control program module, generating an encrypting or decrypting request order, and sending the encrypting or decrypting request order to an encrypting and decrypting main program module; selecting an encrypting or decrypting algorithm according to the encrypting or decrypting request order by the encrypting and decrypting main program module, and encrypting or decrypting the file according to the encrypting or decrypting algorithm. The device comprises the remote control unit, infrared receiving equipment and the computer. The infrared receiving equipment is connected with the computer, and the remote control unit is in communication connection with the infrared receiving equipment. Compared with the prior art, the remote-control-unit-based encrypting and decrypting method and device has the advantages that convenience is brought to common computer users, feasibility is high, the device is clear in structure and the like.

Description

technical field [0001] The invention relates to a file encryption and decryption method and device, in particular to a remote controller-based encryption and decryption method and device. Background technique [0002] At present, personal computers mainly rely on computer antivirus software to resist malicious programs such as viruses and Trojan horses. Some viruses and Trojan horses with good camouflage can always bypass the antivirus software and parasitize in the important files of the computer. Computer anti-virus software can only scan and try to remove viruses and Trojans after the fact, but it cannot guarantee a high anti-virus hit rate. Some anti-virus software even damaged its own anti-virus function after being attacked by viruses. Therefore, it becomes necessary and possible to develop a method and a device for protecting important files of a computer in advance. Viruses and Trojan horses are often firstly stored in important files in the Windows system to achie...
