AIM II
Advanced INFOSEC Machine II

The Advanced INFOSEC Machine II, or AIM II, is an embeddable cryptographic core (processor) developed by General Dynamics C4 Systems in Scottsdale, Arizona (USA), and introduced in 2011. AIM II is an NSA-approved Type-1 encryption product and is the successor to the original AIM that was developed in 2001 by Motorola, shortly before it was acquired by General Dynamics.

AIM II is a further development of the original AIM and is fully backward compatible with it. It was developed for the software-defined Joint Tactical Radio System (JTRS) produced by Thales and General Dynamics. In addition to a number of (speed) improvements and additional crypto­graphic functions, such as elliptic curve algorithms, AIM II is fully programmable.

AIM II can be used in Type-1 and non-Type-1 products and is not classified. In fact, it is not even a Controlled Cryptographic Item (CCI) un­less programmed with Type-1 functionality [2].

in 2015, JTRS AIM was added to the product line [C]. It consists of a reprogrammable embeddable module with thee AIM II chip at its heart. JTRS AIM has three independent cryptographic proces­sors, and supports interoperability with legacy equipment as well as network-centric systems. It has been approved by NSA for information up to an including TOP SECRET. AIM II is backward compatible with software written for the original AIM. Detailed information and brochures are available below and from the General Dynamics website [3].
