摘要: An encryption apparatus and method for providing an encrypted file system are provided. The of the illustrative embodiments uses a combination methodologies so as to reduce amount decryption re-encryption that is necessary in Encrypted File System event needs be modified. interleaved, or alternated, with regard each block plaintext. In one embodiment, Plaintext Block Chaining (PBC) Cipher (CBC) alternated encrypting sequence blocks data. plaintext dependent upon cipher generated previous data more secure than known Electronic Code Book methodologies.
