The endpoint device is configured to share a passphrase with the service processor via shared memory architecture transfer mechanism. The service processor is configured generate the sent hash of a message; encrypt the message, the sent hash, and the nonce value using the passphrase to form an encrypted message; and transmit the encrypted message to the endpoint device over a sideband interface. The storage controller is further configured to decrypt the encrypted message using the passphrase to obtain the message, the sent hash, and the nonce value; compare the nonce value to a counter to determine if the nonce value is an old nonce value; calculate an observed hash of the message; and accept the message when the nonce value is not an old nonce value and the observed hash matches the received hash."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mechanism to secure side band communication between service processor and an end point","description":"An information handling system includes an endpoint device and a service processor.
