We discuss why no existing cipher satisfies the requirements of this application and document our solution which consists of using AES in CBC mode with a dedicated diffuser to improve the security against manipulation attacks. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
