An Embedded RADIUS Client

Allegro’s Remote Authentication Dial In User Service (RomRadius) is an AAA (authentication, authorization and accounting) protocol that offers authentication capabilities to be built into your embedded device. Often utilized to grant access to network resources, RADIUS clients are now found in many application spaces including mobile and M2M environments. RomRadius implements a standards based client/server model that enables remote access servers to communicate with a centralized server to authenticate a user or device and authorize access to network resources.

Specifically designed for use with embedded applications, Allegro’s RomRadius supports multiple RADIUS servers along with PAP, CHAP, MS-CHAP and MS-CHAP2 authentication. Used standalone or tightly integrated with the RomPager family of products, RomRadius will speed product development and decrease time to market while providing quality security services, design flexibility and functionality for your embedded designs.
