What Is Seal? |
|
Answer» The Softwareoptimized Encryption Algorithm (SEAL) was designed by Rogaway and Coppersmith in 1993 as a FAST stream cipher for 32bit machines. SEAL has a rather involved initialization phase during which a large set of tables is initialized USING the Secure Hash Algorithm. However, the use of lookup tables during keystream generation helps to achieve a very fast performance with just FIVE INSTRUCTIONS required per byte of output GENERATED.
