This technology relates to a security device that includes a communication antenna for receiving communication signals and a random number generator for newly generating random numbers based on the received communication signals.
Existing random number generation methods had predictability issues, making it difficult to sufficiently ensure the security of encryption and authentication.
To address this, this technology enhances security with high-quality, unpredictable random numbers by generating them based on the received communication signals themselves.
※ 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,' carried out with the support of the Ministry of Science and ICT.
