a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan.

a possible goal of cryptography, where the idea is to restrict access to documents, equipment, locations, or keys to individuals who are authorized such access.

The RACE Integrity Primitives Evaluation Message Digest (RIPEMD) is a family of cryptographic hash functions.

a subfield of cryptography which constructs and analyzes cryptosystems that preserve the ability to 'search' over encrypted data, for some definition of 'search'.
× 8 × 8
a cryptographic hash function. It was designed for the SHA-3 competition where it became a finalist, but wasn't chosen as SHA-3.

A family of lightweight symmetric block-ciphers designed for good performance in hardware with block sizes ranging from 32 to 128 bits and key sizes ranging from 64 to 256 bits.

A fast 64-bit PRF that can be used as a MAC

Encrypting images so that they can be decrypted without using a computer, e.g. by superimposing two random-looking images.
× 8
a variant of ID-based cryptography intended to prevent the key escrow problem. Only a partial private key is generated by the key generation center (KGC) and the other …

Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001.
× 8
a typically short alphanumeric code used as a software copy-protection mechanism, by requiring a user to enter a valid key before they can use the software.
× 8
a measure of the relative frequency of letters in a cipher text sample, which facilitates cryptanalysis of poly-alphabetic ciphers by allowing determination of the per…

Literature describes everything that has been written and/or visualized (here: in relation cryptography), which ranges from papers to books, and from publications to presentations.

× 7
the common description for a set of cryptographic problems related to playing a fair game over a distance without the need for any trusted third party.
× 7
a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications.
× 7
the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts.
× 7
short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem.

If two numbers $b$ and $c$ have the property that their difference $b-c$ is integrally divisible by a number $m$ (i.e., $(b-c)/m$ is an integer), then $b$ and $c$ are said to be "congruent modulo $m$.…

Time-lock puzzles and other cryptographic schemes intended to ensure that a message cannot be read until a certain time has passed.

material that can be referenced for further information on cryptography.
