Abstract
Systems and techniques are provided for establishing a connection. For instance, a first chiplet root of trust (C-RoT) of a first chiplet of a plurality of chiplets can receive a request for a cryptographic key. The first C-RoT can generate the cryptographic key and wrap the cryptographic key using a wrapping key to generate a wrapped cryptographic key. The first C-RoT can output the wrapped cryptographic key and a second C-RoT of a second chiplet of the plurality of chiplets can receive the wrapped cryptographic key. The second C-RoT can unwrap the wrapped cryptographic key using the wrapping key and can perform an operation based on the cryptographic key.
