Abstract
A requestor and a responder may conduct secure communication by making API calls based on a secure multi-party protocol. The requestor may send a request data packet sent in a API request to the responder, where the request data packet can include at least a control block that is asymmetrically encrypted and a data block that is symmetrically encrypted. The responder may return a response data packet to the requestor, where the response data packet can include at least a control block and a data block that are both symmetrically encrypted. The requestor and the responder may derive the keys for decrypting the encrypted portions of the request and response data packets based on some information only known to the requestor and the responder. The secure multi-party protocol forgoes the need to store and manage keys in a hardware security module.
