Secure Access Control

Abstract

System and method for delivering a secure message to a device. The method includes: digitally signing a first message using a private key of a first entity; encrypting the digitally signed first message using a public key of the device to form a token; further encrypting the token using a public key of a second entity; transmitting the further encrypted token to the second entity; the second entity decrypting the further encrypted token using a corresponding private key of the second entity to recover the token; the second entity delivering the token to the device; the device decrypting the token to recover the digitally signed first message using a corresponding private key of the device; and the device authenticating the digitally signed first message using a corresponding public key of the first entity.
