Security Device for Generating Random Numbers from Received Communication Signals

This technology concerns a security device comprising a communication antenna that receives communication signals and a random number generation unit that generates new random numbers based on the received communication signals.

Existing random number generation methods were predictable, posing a challenge in adequately ensuring the security of encryption and authentication.

To address this, this technology enhances security by generating random numbers based on the received communication signal itself, thereby producing high-quality, unpredictable random numbers.

※ 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.
