Spritz, a drop-in replacement for RC4

Recently at the CRYPTO 2014 conference rump sessions several interesting papers were presented. Ron Rivest presented a paper he and Jacob C. N. Schuldt wrote on finding an improved replacement for the RC4 stream cipher they named Spritz. Their goal was to find a drop in replacement for RC4 that wasn’t susceptible to the known attacks. They used a statistical process to generate and analyze several thousand candidate ciphers.

If anyone is interested in seeing an implementation of Spritz, send us a message at facts@wolfssl.com. We’d love to hear from you.
