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 Weak or outdated algorithms and poor key handling can lead to risks like key compromise, ciphertext manipulation, or replay attacks.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.
Microsoft on Tuesday said it's accelerating its quantum safe security roadmap, stating technology advances in quantum computing are making it essential to replace existing encryption standards sooner than previously expected
Microsoft has brought forward its timelines for transitioning to post-quantum cryptography (PQC)
Today’s encrypted data, such as credentials, may no longer remain confidential in the future because the public-key cryptography protecting it will soon be broken by quantum computers. Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by
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.
