    • An encryption apparatus and method for providing an encrypted file system are provided. The encryption apparatus and method of the illustrative embodiments uses a combination of encryption methodologies so as to reduce the amount of decryption and re-encryption that is necessary to a file in the Encrypted File System in the event that the file needs to be modified. The encryption methodologies are interleaved, or alternated, with regard to each block of plaintext. In one illustrative embodiment, Plaintext Block Chaining (PBC) and Cipher Block Chaining (CBC) encryption methodologies are alternated for encrypting a sequence of blocks of data. The encryption of a block of plaintext is dependent upon the plaintext or a cipher generated for the plaintext of a previous block of data in the sequence of blocks of data so that the encryption is more secure than known Electronic Code Book encryption methodologies.
    • 提供了一种用于提供加密文件系统的加密装置和方法。 说明性实施例的加密装置和方法使用加密方法的组合,以便在需要修改文件的情况下减少加密文件系统中的文件所需的解密和重新加密的量。 关于每个明文块,加密方法被交织或交替。 在一个说明性实施例中,替代了明文块链接(PBC)和密码块链接(CBC)加密方法来加密数据块序列。 明文块的加密取决于明文或为数据块序列中的先前数据块的明文生成的密码,使得加密比已知的电子代码簿加密方法更安全。

    • A method for storing, accessing and interchanging voluminous confidential documents for review by a plurality of parties and for notifying selected ones of a plurality of receiving computers generally operated by unrelated business organizations of receipt by a predetermined host server of such electronic documents from a sender computer for review. The documents are reviewable by each respective receiving computer over a global communications network. The sender computer and the receiving computers are registered in the host server. The method comprises selecting one or more of the plurality of receiver computers to which selected documents are to be reviewed over the global communications network are addressed, storing the respective documents in a first database that is local relative to the sender computer, replicating the documents stored in the first database in a second database that is local relative to the predetermined server, issuing a respective notification message from the predetermined server to the selected receiver computers, each respective notification message indicating replicated documents available in the second database for their respective retrieval over the global communications network, and retrieving the replicated documents in the second database by the selected receiver computers over the global communications network upon a respective user of the selected receiver computers issuing a respective download command signal to the predetermined server.
