The system transmits a request to create a session key from the host system to the DP accelerator, the request including a host public key (PK_O) and the first nonce. The system receives a second nonce (ns) from the DP accelerator, where the second nonce is encrypted using the host public key and a temporary private key (SK_d) corresponding to the temporary public key. The system generates a first session key based on the first nonce and the second nonce, which is utilized to encrypt or decrypt subsequent data exchanges between the host system and the DP accelerator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system to derive a session key to secure an information exchange channel between a host system and a data processing accelerator","description":"According to one embodiment, in response to receiving a temporary public key (PK_d) from a data processing (DP) accelerator, a system generates a first nonce (nc) at the host system, where the DP acce","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233652","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
