To prevent interception Compumatica developed the CompuMobile solution. You can extend your existing smartphone to a phone which can be used for secure calling, secure SMS and secure messaging. CompuMobile is a software application in combination with a secure MicroSD card. The application will be installed from the MicroSD card and works on Android and BlackBerry smartphones. CompuMobile encrypts your phone call by using modern encryption methods.
CompuMobile is unique in the market, because it is a total security solution. It consists of three components. These components take care for additional security and easy use of CompuMobile.
Secure MicroSD card
A special MicroSD is placed in the smartphone. The configuration data and the software application are installed on the MicroSD card. The installation is very easy, and within a few minutes your smartphone will work and you can make secure calls, send secure SMS and use secure messaging. The software application makes use of the encryption methods AES 256 and ECDH. The MicroSD card is EAL5+ certified.
Own VoIP server
The VoIP server works as a kind of telephone exchange and can be managed by the customer himself or be offered as a cloud service by Compumatica. The communication between the smartphones is relayed via the VoIP server which makes use of an own designed protocol to exchange the data. Using this protocol the data is not recognized as a phone call and will not be blocked by the provider.
Key Management System
With the KMS (Key Management System) the administrator can configure the MicroSD, set up user groups and decide who is allowed to communicate with each other. The KMS generates encryption keys and distributes them to the smartphones.
