Examples of public-key cryptography or asymmetric-key cryptography include Diffie-Hellman key exchange, RSA (Rivest–Shamir–Adleman), DSA (Digital Signature Algorithm), ECC (elliptic curve cryptography), and post-quantum cryptography. 3. Hash Functions Hash functions use a one-way encryption algorithm...
Digital Signature Algorithm (DSA) Identity-Based Encryption (IBE) Public Key Cryptography Standards (PKCS) Diffie-Hellman Key Exchange (DHKE) 1. RSA RSA (Rivest-Shamir-Adleman) is one of the earliest public-key cryptosystems. Its strength lies in the mathematical difficulty of factoring large integ...
A digital signature in cryptography is a unique cryptographic fingerprint created by a sender’s private key to verify the authenticity and integrity of digital content. The standard format includes the digital signature standard, the document or message, the sender’s public key for verification, an...
Cryptography - The study of techniques related to all aspects of data security. The word "cryptography" is derived from the ancient Greek words "kryptos" (hidden) and "graphia" (writing). Some aspects of data security: Confidentiality - Keeping data secret. Data Integrity - Ensuring data has...
What is Lattice-based Cryptography? Post-quantum Cryptography: An Introduction (Shweta Agrawal) Lattice-based Cryptography (Daniele Micciancio and Oded Regev) Lattice Cryptography: Understanding Kyber (ML-KEM) and Dilithium (ML-DSA) (Vadim Lyubashevsky) Tutorial introduction to the security of lattice-...
The Payment Card Industry Data Security Standard (PCI DSS) is a widely accepted set of security practices to protect cardholder data and prevent credit card fraud.
As technology advances, public-key cryptography continues to evolve: Post-Quantum Cryptography: Development of algorithms resistant to quantum computing attacks. NIST is in the process of standardizing post-quantum cryptographic algorithms. Homomorphic Encryption: Allows computations on encrypted data without ...

Post-quantum certificates use quantum-safe signature algorithms (like ML-DSA/Dilithium, SLH-DSA/SPHINCS+). This helps ensure that the parties in a digital connection are authenticated, and that data integrity is not violated. Currently, post-quantum certificates are much larger in size than ...
Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
