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 ...
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 ...
XOR cipher. In cryptography, the simple XOR cipher is a type of additive cipher, [ 1] an encryption algorithm that operates according to the principles: A 0 = A, A A = 0, A B = B A, (A B) C = A (B C), (B A) A = B 0 = B, For example where denotes the exclusive disjunction (XOR) operation. [ 2] This operation is sometimes called modulus 2 ...
Inputs a character, as an ASCII code, into a. Newlines or line feeds are both code 10. An end-of-file condition is code 59048. 39 rotr [d] mov a, [d] Rotates the value at [d] by one ternary digit to the right (0002111112 becomes 2000211111). Stores the result both at [d] and in a. 40 mov d, [d] Copies the value at [d] to d. 62 crz [d], a mov a, [d]
The Vigenère cipher is named after Blaise de Vigenère (pictured), although Giovan Battista Bellaso had invented it before Vigenère described his autokey cipher. The Vigenère cipher ( French pronunciation: [viʒnɛːʁ]) is a method of encrypting alphabetic text where each letter of the plaintext is encoded with a different Caesar cipher ...
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]
The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...
Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...
