Original Abstract Submitted
systems and techniques are provided for establishing a connection. for instance, a process may include receiving, at a first chiplet root of trust (c-rot) of a first chiplet of a plurality of chiplets, a request for a cryptographic key; generating, by the first c-rot, the cryptographic key; wrapping, by the first c-rot, the cryptographic key using a wrapping key to generate a wrapped cryptographic key; outputting, by the first c-rot, the wrapped cryptographic key; receiving the wrapped cryptographic key at a second c-rot of a second chiplet of the plurality of chiplets; unwrapping, by the second c-rot, the wrapped cryptographic key using the wrapping key; and performing, by the second c-rot, an operation based on the cryptographic key.
