APPARATUSES FOR ESTABLISHING A HIGHLY SECURE VOICE AMD DATA LINK BETWEEN COMMUNICATING PARTIES

摘要

The invention concerns a system and a device for secure mobile communication. The principle lies in the fact that it uses mobile communication devices (6, 8), e.g. mobile phones or smartphones, in the environment of a mobile communication network to establish a highly secure voice and data communication link between communicating parties. The system consists of an audio module (1, 11), a security device (4, 9), secure data storage (5, 10), a mobile communication device (6, 8), the operator's network (7), and a server system (14). The principle of this invention is setting up a direct secure communication link between two mobile communication devices (6, 8) or terminals, and key management between them. Another principle is development of a highly modular system that can be to the most universal extent possible adjusted to security and infrastructure requirements and whose relevant modules can be easily upgraded remotely. The solution also concerns development of a highly secure, compact and ergonomic security device (4, 9).
