Sierra
Type 1 cryptographic engine - this page is a stub

Sierra is a highly-integrated embeddable cryptographic engine with NSA Type 1 cryptographic algorithms, implemented in a single chip, introduced around 1998 by Harris Corporation (now: L3Harris) in Rochester (NY,USA). Unlike the contemporary Citadel chip – which is a non-Type 1 device – Sierra is used in US military products. It was succeeded in 2004 by the Sierra II chip.
