AT&T Encrypted Mobile Voice Service

Help Protect Conversations with AT&T Encrypted Mobile Voice 

Today, mobile phones handle voice communications that are often highly confidential or sensitive in nature. To protect those calls, we offer AT&T Encrypted Mobile Voice, a powerful security solution that provides support for BlackBerry® and Windows® mobile devices on AT&T GSM and Wi-Fi networks.

AT&T Encrypted Mobile Voice combines hardware and software to transform smartphones into protected devices that support government-grade classifications and provide end-to-end security features for calls. It supports the Controlled Unclassified Information security designation of Sensitive But Unclassified, and is FIPS 140-2 certified.

How It Works: The Hardware and Software Difference

The solution starts with the KoolSpan TrustChip®, a self-contained crypto engine that delivers hardware authentication and call encryption for calls between AT&T Encrypted Mobile Voice users. It fits easily into your smartphone’s microSD™ slot, can be shipped unbranded, and is managed securely over the air.

The KoolSpan TrustChip provides the hardware anchor for One Vault Voice™ from SRA International—an application that integrates seamlessly with your smartphone to let you easily make and take encrypted calls from trusted contacts in just a touch.

Watch how AT&T Encrypted Mobile Voice delivers end-to-end mobile call security for you and your trusted contacts.
