Revere Security was established in 2005 through a grant from the Department of Homeland Security. Initially DHS had tried to apply traditional cryptography, in this case AES-128, to an industrial control system. As a result the system did not function as designed simply because of an end-of-command silence that necessitated a reasonably fast response from the device. The founding team at Revere took up the challenge and developed what is since evolved into the Hummingbird HB-2 cipher.

The cryptographic algorithms developed by Revere Security are one-of-a-kind. They allows users, for the first time, to install highly efficient, industrial-strength encryption and mutual authentication onto microchips within small devices while minimally affecting performance. Simply put, Revere Security's breakthrough technology secures a wide variety of resource-constrained devices while minimally impacting their normal operation:

 

Based on these unique, innovative capabilities, Revere Security has created a cryptographic suite of products that is specifically designed for edge devices. Our ciphers, Hummingbird HB-2 and Passerine, are complemented by innovative key management capabilities, highly secure key handling and an incredibly fast key lookup database. The technologies at the heart of our cryptographic suite have been tested and validated through thousands of hours of cryptanalysis performed by Information Security Systems Inc. (ISSI) and various Universities.
