Atalla Cryptographic Subsystem (ACS)
Utimaco Inc. - FIPS 140 #4992
The ACS is a multi-chip embedded cryptographic module. It consists of a secure hardware platform, a firmware secure loader, and three separate microcontrollers, collectively called the Physical Security Monitor Central Unit or PSMCU). The purpose of the cryptographic module is to load Approved (RSA and ECDSA signed) application programs, called "personalities", in a secure manner.
