Abstract
An authentication request message is sent from a first computing device to a second computing device, wherein the first computing device and the second computing device communicate via a machine-to-machine communication protocol, and wherein the authentication request comprises a token issued by the second computing device and stored in a key obfuscation block of the first computing device. A challenge message is received at the first computing device from the second computing device. In response to the challenge message, a session key is computed at the key obfuscation block of the first computing device, wherein the session key is computed based on a secret shared between the first computing device and the second computing device. Upon generating the session key, the first computing device extracts a value from the challenge message and generates an authentication delegate based on the extracted value. The authentication delegate is sent from the first computing device to a third computing device for verification to allow the first computing device access to the third computing device.
