Abstract
The disclosed technology is generally directed to secure transactions. In one example of the technology, a secure encrypted communication tunnel between the enclave and a hardware security module (HSM) may be established and used. Establishing the tunnel includes the following steps. A session public/private enclave key pair, including a session enclave private key and a session enclave public key, may be derived from the public/private key pair of the enclave. The session enclave public key may be sent to the HSM. A session HSM public key may be received from the HSM. Additional information may be encrypted with the session HSM public key. The encrypted additional information may be sent to the HSM. Further encrypted information may be received from the HSM. The further encrypted information may be decrypted with the session enclave private key.
