Background for this topic.
Cryptography secures information by converting data into coded formats using mathematical algorithms, enabling confidentiality, integrity, and authentication. Common cryptographic techniques include encryption, which hides data content; hashing, which verifies data integrity; and digital signatures, which confirm origin and authenticity. These methods protect data in transit and at rest from unauthorized access or tampering.
In information security, cryptography’s effectiveness depends on algorithm strength, proper key management, and resistance to cryptanalysis. Weak or outdated algorithms and poor key handling can lead to risks like key compromise, ciphertext manipulation, or replay attacks. Security practitioners must monitor cryptographic standards, manage keys securely, and assess cryptographic components during vulnerability analysis to maintain robust defenses against targeted attacks.

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.
