Abstract
A client device may be provisioned with a digital certificate to support various operations. The client may transmit a certificate request to a server. The server may initiate a key agreement process using a short-lived private key generated at the server and a public key of the device to derive a symmetric key. The symmetric key may be used to encrypt a payload that includes the digital certificate and an associated private key. Further, the server initiates a key agreement process using the partial private key that was generated for the client and the short-lived public key. A partial key agreement result, and the encrypted payload may be transmitted to the client. The client may complete the key agreement process using the partial key agreement result and a respective portion of the private key. The client may derive the encryption key and decrypt the payload to access the digital certificate.
