Tags

A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

Cryptographic functions which transform plaintext into ciphertext or the other way around.
 × 3 × 3 × 27
Ciphers invented before the era of computers and modern cryptographic theory. Classical ciphers typically operate on letters instead of bits and are usually designed to be implemented by hand or using…

Difficulty of finding two different inputs that hash to the same value
 × 7
a protocol where one party commits themselves to a secret value without revealing it. At a later point, the value can be revealed.

Complexity describes - in simple words - how hard (complex) it is to reach a specific goal; and under which conditions. In cryptography, this mostly ends up in using the complexity theory to analyze t…

Convergent encryption, also known as content hash keying, is simply encrypting a file using a symmetric encryption key which is the secure hash of the plaintext of the file.
 × 4
Copy protection or content protection covers various mechanism, such as DRM and software license keys, used to restrict the unauthorized copying or use of software or digital media.
× 6 × 187
analysing cryptographic algorithms, potentially uncovering weaknesses in them (e.g. "breaking" them or casting doubts on their actual security)

an encryption mode, that builds a random-access stream-cipher from a block-cipher.

A structured set of data held in a computer, esp. one that is accessible in various ways.

(or Data Encryption Standard), a (symmetric) block cipher using a 64 bit block size, with keys of size 56 bit, the standard US block cipher from 1976 to 2001.
× 6 × 4
a form of cryptanalysis which studies cryptographic algorithms by observing how differences in input affect differences on output.

The most famous key exchange algorithm with perfect forward-secrecy.
× 7
Money that may be transferred electronically from one party to another during a transaction.

the number of times a generator of a group must be multiplied by itself to produce a known number. By choosing certain groups, the task of finding a discrete l…

a United States Federal Government standard or FIPS for digital signatures. It was proposed by the National Institute of Standards and Technology (NIST) in Aug…
 × 3 × 16
a mode of operation for a block cipher, with the characteristic that each possible block of plaintext has a defined corresponding ciphertext value and vice versa.
