TL;DR: A 128-Kbit EPROM is described that can protect systems and software from unauthorized use and the use of unauthorized software with authorized systems, and vice versa, is prevented.
Abstract: A 128-Kbit EPROM is described that can protect systems and software from unauthorized use. The KEPROMTM keyed-access EPROM will not allow read access to its array until an authentication handshake has been completed. The handshake uses two EPROMs and involves encryption of pseudorandom numbers using a secret 64-bit key stored in each part. Security is provided by requiring the two EPROMs to contain the same 64-bit key before either will grant read access. Because the secret key is known only to the system manufacturer, the use of unauthorized software with authorized systems, and vice versa, is prevented. KEPROMTM is a trademark of INTEL Corporation.
