SEAL (cipher)

From Wikipedia, the free encyclopedia

SEAL (Software-Optimized Encryption Algorithm) is a very fast stream cipher optimised for machines with a 32-bit word size and plenty of RAM.

The first version was published by Phillip Rogaway and Don Coppersmith in 1994. The current version, published in 1997, is 3.0. SEAL is covered by two patents in the United States, both of which are assigned to IBM.
