  • Stream cipher encryption application accelerator and methods thereof
    Patent number: 7903813
    Abstract: A system for encrypting and decrypting data formed of a number of bytes using the ARCFOUR encryption algorithm is disclosed. The system includes a system bus and an encryption accelerator arranged to execute the encryption algorithm coupled to the system bus. A system memory coupled to the system bus arranged to store a secret key array associated with the data and a central processing unit coupled to the system bus wherein encryption accelerator uses substantially no central processing unit resources to execute the encryption algorithm.
    Type: Grant
