Formally, a digital signature scheme is a triple of probabilistic polynomial time algorithms, (G, S, V), satisfying: G (key-generator) generates a public key (pk), and a corresponding private key (sk), on input 1 n, where n is the security parameter. S (signing) returns a tag, t, on the inputs: the private key (sk), and a string (x).
The Digital Signature Algorithm ( DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, two keys are generated: data can only be encrypted with the public key and encrypted ...
An electronic signature, or e-signature, is data that is logically associated with other data and which is used by the signatory to sign the associated data. This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (e.g., eIDAS in the European Union, NIST-DSS in the USA or ...
3 June 1997. Third reading. 3 June 1997. Amended by. Digital Signature (Amendment) Act 2001 [Act A1121] Status: In force. The Digital Signature Act 1997 ( Malay: Akta Tandatangan Digital 1997 ), is a Malaysian law enacted to make provision for, and to regulate the use of, digital signatures and to provide for matters connected therewith.
EdDSA. In public-key cryptography, Edwards-curve Digital Signature Algorithm ( EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. [ 1] It is designed to be faster than existing digital signature schemes without sacrificing security.
As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits. [1] For example, at a security level of 80 bits—meaning an attacker requires a maximum of about operations to find the private key—the size of an ECDSA private key would be ...
Blind signature. In cryptography a blind signature, as introduced by David Chaum, [ 1] is a form of digital signature in which the content of a message is disguised ( blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature.
NTRU. NTRU is an open-source public-key cryptosystem that uses lattice-based cryptography to encrypt and decrypt data. It consists of two algorithms: NTRUEncrypt, which is used for encryption, and NTRUSign, which is used for digital signatures. Unlike other popular public-key cryptosystems, it is resistant to attacks using Shor's algorithm.
