Abstract: Systems and techniques are provided for secure processing. For instance, a process can include generating a model signing key, wherein the device is associated with a device model, and wherein the model signing key is shared by apparatuses of the device model; obtaining a certificate for a device-unique public key of the apparatus; signing the device-unique public key based on the model signing key; and transmitting the signed device-unique public key for authentication.

Abstract: 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.
