The Quantum Sky Is Falling! Understanding The Quantum Threat To Network Security
Cisco News, Wednesday, March 12th, 2025
Confidentiality is a fundamental pillar of information security. In sensitive deployments, such as those involving federal governments, military and defense agencies, and large financial institutions, the demand for confidentiality extends well beyond the typical 5 to 10 years, often reaching 20 years or more.
The same also applies to telecom operators and enterprises providing services to any of these critical agencies. With the existing classical computers, this requirement of forward secrecy for encryption could be met easily as breaking the asymmetric cryptography (deriving the private key for a given public key) would take well beyond the timelines needed to maintain the data confidentiality.
