초록 ▼

A system for determining when a remote computer user is authorized to communicate with a host computer and to establish a ciphering key to be used for the communications session. A random number is generated at the host computer, ciphered under the user\s PIN, and sent to the remote user where it is deciphered under the PIN to provide a session key. In one embodiment, this key is reciphered under the PIN, sent to the host computer, and deciphered under the PIN. The deciphered value is equal to the generated random number when the correct PIN\s are used, thereby validating the user. In another embodiment, the deciphered random number at the remote user location is used as a key to cipher the PIN which is sent to the host, deciphered under the random number, and compared with the PIN existing at the host. Subsequent, ciphering can use the determined session key as a ciphering key. Additional security can be realized by adding random digits to the PIN, masking some of the developed keys, and sending the user ID to the host in ciphered form. This system does not require a stored key in the remote computer or the transfer in the clear of the PIN between computers.

대표청구항 ▼

A security system for validating the authority of a remote user to communicate with a host device, said system comprising: means at the host device for storing user ID and personal identification number (PIN) information; means for sending the ID information across a communications channel from the remote user to the host device; means at the host device for providing a non-predetermined signature value; means at the host device for ciphering the signature value under a first key value which is dependent upon at least a portion of the stored ID and PIN information; means for sending the ciphered signature value across the communications channel to the remote user; means at the remote user location for deciphering the ciphered signature value received from the host device under a second key value which is equal to said first key value and derived from the same information as said first key value; means at the remote user location for ciphering the deciphered signature value under a third key value and for sending the ciphered signature value to the host device; and validation means at the host device for deciphering the ciphered signature value received from the remote user location and for determining if the deciphered signature value is equal to the signature value originally provided by the host device.
