Abstract

Method to establish a secure channel between the party of a software payload and the software payload itself when running into a hardware-based trusted execution environment, HW TEE, at the instance of a cloud service provider, including sending, by the party, a nonce to the software payload; generating, by the software payload, a payload key pair: public key and private key; mixing, by the software payload, the payload public key with the nonce; computing, by the HW TEE, an attestation using this nonce mixed with the payload public key; sending, by the software payload, the attestation, and the payload public key to the party; verifying, by the party, the attestation using the sent nonce mixed with the received payload public key; generating, by the software payload and the party, a session key; and establishing a secure channel between the party and the software payload running into the HW TEE.
