Learn about the digital signature scheme based on discrete logarithms, invented by Taher Elgamal in 1985. Find out how it works, its history, security and variants.
Schnorr signature is a digital signature scheme based on discrete logarithm problems and hash functions. It is simple, efficient and secure, and can be used for identification and signature purposes.
Learn how DSA works as a public-key cryptosystem for digital signatures, based on modular exponentiation and discrete logarithm problem. See the key generation, signing and verification operations, and the history and specification of DSA.
Learn about the Paillier cryptosystem, a probabilistic asymmetric algorithm for public key cryptography based on composite residuosity. Find out its key generation, encryption, decryption, homomorphic properties, and applications in electronic voting, cash, and auctions.
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. Learn about the definition, history, methods, and applications of digital signatures, as well as the difference between digital and electronic signatures.
[3] [4] [5] The Rabin signature scheme was the first digital signature scheme where forging a signature could be proven to be as hard as factoring. The trapdoor function was later repurposed in textbooks as an example of a public-key encryption scheme, [ 6 ] [ 7 ] [ 1 ] which came to be known as the Rabin cryptosystem even though Rabin never ...
ECDSA is a cryptographic algorithm that uses elliptic-curve cryptography to sign messages. Learn how it works, its key and signature sizes, its verification and recovery methods, and its security issues.
A BLS digital signature, also known as Boneh–Lynn–Shacham [1] (BLS), is a cryptographic signature scheme which allows a user to verify that a signer is authentic.. The scheme uses a bilinear pairing for verification, and signatures are elements of an elliptic curve group.
