Feb 13, 2023 · Cryptography is the study of information hiding and verification. It includes the protocols, algorithms and strategies to securely and consistently prevent or delay unauthorized access to sensitive information and enable verifiability of every component in a communication. Cryptography is derived from the Greek words: kryptós, "hidden", and ...
Wikimedia Commons has media related to Cryptography. Cryptography is the study of ways to convert information from its normal, comprehensible form into an obscured guise, unreadable without special knowledge — the practice of encryption. In the past, cryptography helped ensure secrecy in important communications, such as those of spies ...
Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions support important standards of post-quantum cryptography. [1] Unlike more widely used and known public-key schemes such as the RSA, Diffie ...
Paul Kocher, US, discovered differential power analysis. Mitsuru Matsui, Japan, discoverer of linear cryptanalysis. David Wagner, US, UC Berkeley, co-discoverer of the slide and boomerang attacks. Xiaoyun Wang, the People's Republic of China, known for MD5 and SHA-1 hash function attacks.
Post-quantum cryptography. Post-quantum cryptography ( PQC ), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. The problem with popular algorithms currently ...
Cryptosystem. In cryptography, a cryptosystem is a suite of cryptographic algorithms needed to implement a particular security service, such as confidentiality ( encryption ). [1] Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption. The term cipher (sometimes cypher) is ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5.
