IPC: H04L9/32
Filed: 2000-07-27
Abstract: PURPOSE: A security method is provided to protect a server against a hacker by storing encoded identification and a value for an integrity identification and making the encoded information be decoded when the encoded identification is identical to the value of the integrity identification when a client tries to connect to a server. CONSTITUTION: If a secret number is inputted, a secret number generating part converts the secret number into a 8-bit secret key through a specific function. The secret key is temporarily stored in a buffer of a decoder part through a comparison and process part, and the input identification and information are encoded through a stream encoding part. The encoded identification and information are transferred to an integrity identification value generating part, which calculates an integrity identification value. The integrity identification value is added to the encoded identification and information, and a resultant value is transferred to the comparison and process part. The comparison and process part scans a member information database to search whether the transferred identification and information are identical to those stored in the member information database. If so, encoding information of the database is transferred to a decoding part. If not, the secret key stored in the buffer is deleted, and a disagreement result is transferred to a central processing unit.
