Abstract: The present disclosure generally relates to systems and methods for initiating secure network connections at a first computing device without blocking operation of a real-time processor that handles latency-sensitive input/output (I/O) operations. In some implementation examples, the real-time processor obtains a request to establish a secure connection with a second computing device over a network. The real-time processor can enqueue into an inter-processor queue a request for performing a cryptographic operation. An additional processor can obtain the request and perform the cryptographic operation. After completing the cryptographic operation, the additional processor can enqueue information indicating the cryptographic operation is completed into the inter-processor queue. The real-time processor can obtain the information from the inter-processor queue and use the information to establish the secure connection with the second computing device.
