  • High performance hardware-based execution unit for performing C2 block cipher encryption/decryption
    Patent number: 9014370
    Abstract: A system and method for encrypting and/or decrypting data with a Cryptomeria (C2) cipher may be provided that generates C2 round keys in parallel. Accordingly, data may be encrypted or decrypted at least twice as fast as without the system. A storage device may encrypt data written to the storage device and/or decrypt data read from the storage device with such a system.
    Type: Grant

  • STORAGE SYSTEMS THAT CREATE SNAPSHOT QUEUES
    Publication number: 20140344536
    Abstract: A storage system may include a queue included in a memory and a controller configured to store commands received from a host in the queue. The queue may have a linked-list configuration. In response to a triggering event, the controller may take a snapshot of the queue, creating a snapshot queue. The snapshot queue may have a linear configuration. Subsequent analysis or parsing of queued information may be performed on the linear snapshot queue instead of the linked-list queue. Modifications to the linear snapshot queue may be corresponding made to the linked-list queue.
