The Fusion Security Module is based upon a PKI security module that has been designed specifically for embedded systems, resulting in an extremely small footprint solution. A further advantage of a “base” security component is that all of the upper layer modules are based upon this low level component. This sharing of security components allows for a substantially smaller code base when mixing higher-level security components such as IPsec, VPN, IKE, SSL, SIPS, SRTP etc.

*A reference design is a sample electronics circuit design that shows engineers how to utilize the latest developments in microchips in their own products. Using a reference design as a base, it is possible today for a device manufacturer to incorporate a new technology into existing designs in a few weeks, and have products available to ship not long after.
