Title: Key distribution method using personal identification information
Inventor: PARK SANG-JUN
IPC: H04L9/14
Filed: 1993-12-17
Granted: 1995-09-25
Abstract: The device provides an efficient and safe shared key distribution method by using the personal identification informations. The method comprises the steps of: entering the secret key and personal identification information at the terminal; generating the random number using random number generator at each terminal; encrypting the generated random number using a secret key of the user; transmitting the personal identification information and the computed result to the opposite terminal through the communication channel; and decoding the secret shared key by using generated random number and received information.

Title: Direction convertion method for display message
Inventor: KIM JAE-HO
IPC: G09G5/38
Filed: 1993-12-18
Granted: 1996-12-20
Abstract: The method is to display a message by converting the display location of the message into the wanted direction when a direction conversion key is inputted in the state that the message is displayed. The method comprises: a direction conversion key input step of inputting the direction conversion key in the state that a message is displayed; a message direction-detecting step of detecting the present displayed message direction state; and a message direction conversion step of displaying the message by converting the message direction into the wanted direction according to the input of the direction conversion key.
