This technology relates to a secure communication device and program comprising a voice input terminal, an antenna for receiving RF signals, and a control unit that encrypts voice signals based on received RF signals and transmits them to a paired receiver.
Existing voice communication systems, which use fixed encryption keys, were vulnerable to eavesdropping and hacking, making it difficult to ensure the reliability of secure communication.
To address this, this technology encrypts voice signals in real-time based on received RF signals and transmits them only to a paired receiver, thereby achieving secure voice communication robust against eavesdropping.
※ This invention is the result of the project 'Development of Electric Signal-Based High-Quality Cryptographic Key Generation and Core Security Technologies for Safe 4th Industrial Services,' conducted with the support of the Ministry of Science and ICT.
