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, which uses fixed encryption keys, has been 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 implementing secure voice communication robust against eavesdropping.
※ This invention is the result of the project 'Development of High-Quality Cryptographic Key Generation and Core Security Technologies Based on Electrical Signals for Secure 4th Industrial Services,' conducted with the support of the Ministry of Science and ICT.
