Abstract:
1. A method for queue look-ahead key setup in a cryptographic system, the method comprising: receiving jobs in queue with each of the jobs consisting of work data and key data that is associated with a key type; designating plural duplicate key cryptographic engines using a same encryption scheme processing the key data of the jobs; designating plural duplicate work cryptographic engines using a same encryption scheme processing the work data of the jobs, the plural duplicate work cryptographic engines being different cryptographic engines from the plural duplicate key cryptographic engines; looking ahead into the job queue for one or more succeeding jobs to be performed; assigning the one or more succeeding jobs to one of the plural duplicate key cryptographic engines; outputting, from the one key cryptographic engine, processed key data to memory; and inputting the processed key data to one of the plural work cryptographic engines when the one work cryptographic engine is ready to process work data relating to the processed key data.
