摘要
A system for controlling access to an encrypted document in which a computer receives a request to access the encrypted document, the access request comprising a user ID and a user password. The computer performs a one-way hash function on the user password to generate a hash value. The computer searches an access control table for the hash value which indicates an authorization for the user to access the encrypted document and corresponds to a document password encrypted with the user password. The computer decrypts the document password using the user password. The computer decrypts the encrypted document using the decrypted document password.
