Quantum computing could undermine widely used public-key encryption, driving research into quantum-resistant algorithms and secure migration planning.

Background for this topic.
Quantum computing uses quantum-mechanical effects in qubits to solve some problems differently from conventional computers. In information security, its significance is primarily cryptographic: a sufficiently capable, fault-tolerant quantum computer could use Shor’s algorithm to break RSA and elliptic-curve cryptography, which protect certificates, key exchanges, signatures, and encrypted archives. Quantum computing is not expected to break all cryptography equally; symmetric encryption and cryptographic hashes generally require larger security parameters rather than replacement for the same reason.
The practical concern is “harvest now, decrypt later”: adversaries can collect encrypted traffic today for future decryption, especially when data must remain confidential for years. Organizations should inventory public-key algorithms and long-lived sensitive data, assess dependencies such as certificates and protocols, and plan migration to standardized post-quantum cryptography with crypto-agile systems. Quantum key distribution is a separate, specialized communications approach; it does not replace endpoint security, authentication, or conventional key-management controls and has significant deployment constraints.

Experts Detail Migration Scope, Timelines and Governance Gaps in Going Quantum-SafeMigrating to post-quantum cryptography isn't a weekend patch. It's one of the largest transformations an enterprise will undertake, and it will require a multi-year program spanning infrastructure, vendors, governance and policy, according to a panel of experts.
With federal PQC deadlines set for 2030 and 2031, CISOs face a multi-year transformation program that most organizations have not yet started. The window for orderly execution is narrowing fast. The post What the post-quantum executive order really demands of CISOs appeared first on CyberScoop.
Healthcare organizations should prepare for post-quantum cryptography without overreacting to hype, said John Frushour, CISO of New York-Presbyterian Hospital. Stronger encryption standards, commercial software support and attention to medical devices can help providers manage emerging risks.
Bank of Ireland's Francis Gorman Shares Strategies for Successful Quantum MigrationMost organizations give the migration to quantum-safe cryptography to the CISO. But that puts a cross-business change in the wrong hands. Accountability belongs with senior leaders who can influence the whole enterprise, says Francis Gorman, head of Bank of Ireland's security center of excellence.
