An accelerator circuit includes a copy engine (CE) with AES-GCM hardware configured to perform both encryption and authentication of data transfers for multiple applications or multiple data streams in a single application or belonging to a single user. The CE splits a data transfer of a specified size into a set of partial transfers. The CE sequentially executes the set of partial transfers using a context for a period of time (e.g., a timeslice) for an application. The CE stores in a secure memory for the application one or more data for encryption or decryption (e.g., a hash key, a block counter, etc.) computed from a last partial transfer. The one or more data for encryption or decryption are retrieved and used when data transfers for the application is resumed by the CE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fairly utilizing multiple contexts sharing cryptographic hardware","description":"Apparatuses, systems, and techniques for supporting fairness of multiple context sharing cryptographic hardware.
