AUTHENTICATED CRYPTOGRAPHY PATENT NO.: 7,827,408

Message encryption and authentication are typically performed separately. In other words, a message is encrypted using one method and then a cryptographic hash of the message is generated using a second method. This invention is a device for and method of encrypting and authenticating a message and authenticating any additional information. The present invention provides a cryptographically stronger authentication method and is more efficient to implement, than the prior art.

VALUE: Provides combined authenticated encryption in efficient manner. Does not require random numbers, two encryption keys, or checksums.
