Revoking apparatus for supporting a data encryption and decryption system and method for realization

The present invention relates to data encryption and decryption system and method for implementing a revocation operation support apparatus, the system comprising a mobile device, and the encryption control sub enterprise network, internal network installed two firewalls, and Internet isolation of the first firewall DMZ placing businesses in the region's mail server and control server certificates, encryption control subnets, subnet control the encryption and enterprise network isolation, encryption control only connection encryption machine and administrators working machine within a subnet after the second firewall; mobile device, the data is double-encrypted symmetric key encryption and decryption need to go through RSA and RSA key on a mobile device key encryption machines; all encryption machines share a blacklist database, move in the blacklist equipment sent to the service request will be denied service. The beneficial effect of the invention is: after the mobile device and TF card is lost, which quickly TF card revoked by a simple operation; after TF card is revoked, picked up people lost access to mobile devices even if they know the password can not be decrypted mobile data encryption device.
