 ipsec× 5 information-theory× 5 concerned with sending messages via electronic signals in the most efficient and error-free way. key-wrap× 5 knapsack× 5 the problem of determining which numbers from a given collection of numbers have been added together to yield a specific sum: used in cryptography to encipher (and sometimes decipher) mess… literature× 5 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. proxy-re-encryption× 5 resources× 5 material that can be referenced for further information on cryptography. searchable-encryption× 5 a subfield of cryptography which constructs and analyzes cryptosystems that preserve the ability to 'search' over encrypted data, for some definition of 'search'. schnorr-identification× 5 The Schnorr Identification Protocol relies upon the security of the Discrete Logarithm Problem. Schnorr's protocol was introduced after, and is comparable to, the identification protocol of Fiat and S… congruence× 5 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 $m$.… constants× 5 Fixed, more or less arbitrary parameter values that appear in the definitions of cryptographic schemes, such as fixed initialization vectors for hash functions or S-box tables for block ciphers. dual-ec-drgb× 5 short for Dual Elliptic Curve Deterministic Random Bit Generator; a pseudorandom number generator based on the elliptic curve discrete logarithm problem. siv× 5 a two-pass AEAD block cipher mode of operation described in RFC 5297. It can be used either for key-wrap (nonce-less deterministic authenticated encryption) or… s-mime× 5 Secure/Multipurpose Internet Mail Extensions, or short S-MIME, is a standard for public key encryption and signing of MIME data. wpa2-psk× 5 Wi-Fi Protected Access 2 - Pre-Shared Key (also called WPA or WPA2 Personal) is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was… universal-hash× 5 tea× 4 a block cipher by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; notable for its simplicity of description and implementation. simon× 4 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. embedded× 4 a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. ecies× 4 Elliptic Curve Integrated Encryption Scheme (ECIES) is a public key encryption system proposed by Victor Shoup in 2001. education× 4 Questions related to the teaching and learning of cryptography. camellia× 4 a 128-bit, symmetrical block cipher jointly developed by Mitsubishi and NTT of Japan. avalanche× 4 evident if, when an input is changed slightly (for example, flipping a single bit) the output changes significantly (e.g., half the output bits flip). predicate-encryption× 4 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. pbkdf× 4 a Password Based Key Derivation Function, which can be used to derive key data or derive a "password hash" from a salt and password. luby-rackoff× 4 a Feistel cipher where in each round the nonlinear function used is assumed to be chosen uniformly at random from the set of all such functions. These ciphers are mainly of th… key-escrow× 4 key-check-value× 4 mixnets× 4 routing protocols that create hard-to-trace communications by using a chain of proxy servers known as mixes which take in messages from multiple senders, shuffle them, and send them b… ocb× 4 The Offset CodeBook Mode, an authenticated encryption mode of operation for a block cipher. needham-schroeder× 4 Needham–Schroeder refers to both, a symmetric key or a public key authentication protocol. mixing-function× 3 to "scramble" or mix the internal state of a hash (or cipher) function. The input to the function is the current internal state and the output of the function bec… md4× 3 RFC 1320 — the MD4 message-digest algorithm — is a cryptographic hash function with a digest length is 128 bits, developed by Ronald Rivest in 1990. kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. key-recovery× 3 A means of recovering cryptographic keys when the usual means for obtaining them is unavailable.; the ability to uncover the secret key to a cryptographic message. key-rotation× 3 Key rotation refers to a schedule or process for changing the key material.
