Networks Must Evolve with Cryptography

The rapid evolution of cryptography is forcing network infrastructure to adapt quickly to changing security needs. Post-quantum cryptography (PQC) is a crucial aspect of this shift, as it prepares networks for the challenges posed by quantum computers.

Traditional networking platforms often take years to develop and remain deployed for over a decade. During this time, cryptographic algorithms and standards continue to evolve, while new vulnerabilities and implementation risks emerge.

Cisco recognizes that network infrastructure must be designed to accommodate future changes in cryptography. This is why the company advocates for 'crypto agility,' which enables networks to update cryptographic algorithms, protocols, libraries, and implementations without disrupting underlying infrastructure.
