Patent

CA 2304433

Access to computer systems is often protected by a password or pass phrase. A pass phrase has the advantage that it can have sufficient information content to permit its conversion into a secure cryptographic key by the use of a suitable hash function. These have the advantage that, when a user employs a high-quality password or pass phrase (i.e., one resistant to cracking), and avoids recording it where a hostile person might find it, and succeeds in remembering it, the password or pass phrase provides convenient and secure access to the resources which it protects.
