Abstract

A modified measured boot approach is utilized for establishing a secure communication link between two devices. Each device may execute a respective boot process until the device reaches the stage responsible for establishing the communication link with the other device. Each device may exchange its respective self-signed certificate and extend its certificate chain with the self-signed certificate received from the other device. A secure link can be established using the public key of the other device as a based key for a key exchange protocol.
