An authenticate processing for the information system in Industrial Technology Research Institute

A technique for storing, processing, and transmitting highly sensitive information over a computer network in the Industrial Technology Research Institute's application system is described. Both secrecy information and user passwords for accessing this information are encrypted by using the public key cryptosystem of the RSA (River-Shamir-Adleman) scheme and El Gamal public key cryptosystem. Based on the special characteristics of this system where the development system and product system are located in different computers, the concept of the digital signature is used to let authorized users execute authentication programs and extract information.<
