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 ...
Rabin cryptosystem. The Rabin cryptosystem is a family of public-key encryption schemes based on a trapdoor function whose security, like that of RSA, is related to the difficulty of integer factorization. [ 1][ 2] The Rabin trapdoor function has the advantage that inverting it has been mathematically proven to be as hard as factoring integers ...
Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. [ 1][ 2][ 3] A message is concealed in the presentation of text, rather than its content. Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces).
In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
Learning with errors. In cryptography, learning with errors ( LWE) is a mathematical problem that is widely used to create secure encryption algorithms. [ 1] It is based on the idea of representing secret information as a set of equations with errors. In other words, LWE is a way to hide the value of a secret by introducing noise to it. [ 2]
Decoding a general linear code, however, is known to be NP-hard, [3] however, and all of the above-mentioned methods have exponential running time. In 2008, Bernstein, Lange, and Peters [ 5 ] described a practical attack on the original McEliece cryptosystem, using the information set decoding method by Stern. [ 11 ]
Esoteric programming language. An esoteric programming language (sometimes shortened to esolang) is a programming language designed to test the boundaries of computer programming language design, as a proof of concept, as software art, as a hacking interface to another language (particularly functional programming or procedural programming ...
A cryptographic hash function ( CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [ 1] the probability of a particular. n {\displaystyle n} -bit output result ( hash value) for a random input string ("message") is.
