SecuSmart has developed a mobile solution that fits on a micro-SD card. It can be used in mobile devices for end-to-end, real-time encryption. Currently, the company supports BlackBerry, Android and Nokia phones running Symbian. The SecuVOICE chip creates no additional latency beyond what’s already present in the digital voice network. The company also produces a landline voice security system that can communicate with mobile phones running SecuVoICE. Both types of systems meet NATO-restricted and EU-restricted security levels.”]
