Abstract
Encryption and decryption is achieved without the requirement for updating of the encryption key or re-encryption of an encrypted file when a shared encrypted file is generated, renamed or deleted.In response to a request to read or store a shared encrypted file, a filter driver in a client computer receives client authentication from a key management server and acquires a key list having pairs of UNC path names and encryption keys corresponding to shared encrypted folders allowed to be accessed from the key management server. The filter driver accesses a shared encrypted folder as a destination of the read or store request and performs decryption or encryption of the shared encrypted file by using an encryption key of the key list corresponding to a UNC path name concerned with the UNC path name to be accessed when the UNC path name concerned is present in the key list.
