The Importance of Confidentiality in Information Security: A Quantum Perspective
Confidentiality serves as a key component of information security, especially within sensitive environments such as federal agencies, military departments, and major financial institutions. The need for confidentiality frequently exceeds the traditional duration of five to ten years, often extending to twenty years or even longer.
This necessity also applies to telecom providers and companies serving these critical organizations. Generally speaking, existing classical computing resources can adequately fulfill the forward secrecy requirements essential for encryption today since breaking asymmetrical cryptography—such as deriving private keys from public ones—typically takes far longer than these confidentiality timelines.
