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.
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...
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 ...
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...
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.
These, in turn, are broken down into different types. We’ll explore each one separately. What is the Symmetric Encryption Method? Also called private-key cryptography or a secret key algorithm, this method requires the sender and the receiver to have access to the same key. So, the ...
Digital Signature Algorithm (DSA): Built on the principles of modular exponentiations, DSA is the gold standard for verifying electronic signatures and was created by the National Institute of Standards and Technologies. Identity-based Encryption (IBE): This unique algorithm negates the need for a ...
Six years later, NIST officially published the world’s first three post-quantum cryptography standards. IBM researchers, in collaboration with several industry and academic partners, developed two of these post-quantum cryptographic algorithms: ML-KEM (originally CRYSTALS-Kyber) and ML-DSA (originally...
