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 Weak or outdated algorithms and poor key handling can lead to risks like key compromise, ciphertext manipulation, or replay attacks.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.
In the next 10 years, public-key encryption needs to be replaced by post-quantum techniques that can stand up to the new challenges.
Biden's executive order pushes new NIST quantum-cryptography standards and directs federal government to move toward quantum-resistant cybersecurity.
