Cryptographic security refers to the techniques and methods used to protect information by transforming it into a format that is unreadable without the appropriate key or access credentials. This ensures confidentiality, integrity, and authenticity of data in communication systems, making it crucial for secure information exchange. In practical QRNG implementations and applications, cryptographic security plays a significant role in ensuring that the randomness generated can be reliably used for encryption, thus protecting sensitive information from unauthorized access.
