The deployment of the 3591 CES-128 Voice Encryptor enables commanders to bridge the interoperability gap between multiple vendor fielded radio networks.

Codan's 3591 CES-128 Voice Encryptor provides communications security through use of a proprietary 128-bit encryption algorithm. The unit’s compact size supports multiple deployment scenarios from manpack to mobile to base platforms.

It features a simple, intuitive 6-button interface for control of volume, encryption key and Secure/Clear Status. Key programming is achieved using Codan’s standard KMS (Key Management Software) or KFS (Key Fill Software), as used with Codan’s transceivers.
