 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× 4 Secure/Multipurpose Internet Mail Extensions, or short S-MIME, is a standard for public key encryption and signing of MIME data. three-pass-protocol× 4 The three-pass protocol uses commutative encryption to let two people communicate privately without having to exchange keys in advance. transport-security× 4 Transport security about establishing a real time secure channel from a sender to a receiver. Transport security generally requires more protection and a more intricate protocol than securing data at … pkcs8× 4 Public-Key Cryptography Standard, number 8, describes the Private-Key Information Syntax Standard which is used to carry (encrypted or unencrypted) private certificate keypairs. See [RFC 5208](http://… probabilistic-encryption× 4 the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts. predicate-encryption× 4 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. key-rotation× 4 Key rotation refers to a schedule or process for changing the key material. key-escrow× 4 kerberos× 4 key-check-value× 4 md4× 4 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. mixing-function× 4 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… needham-schroeder× 4 Needham–Schroeder refers to both, a symmetric key or a public key authentication protocol. ephemeral× 4 short-lived, like (for example) an ephemeral key, which is a key that only exists within the lifetime of a communication session. dpa× 4 homomorphic-signatures× 4 A homomorphic signature scheme (also malleable signature scheme) is a digital signature scheme that allows computations on signed data (without access to the secret signing key) while preserving the… hamming× 4 a family of binary, linear error-correcting codes that are used to detect and correct data transmission errors. Hamming codes are able detect up to two simultaneous bit errors and ca… cryptdb× 4 an SQL-Aware encrypted database system from MIT cryptoapi× 3 The Cryptographic Application Programming Interface is an application programming interface included with Microsoft Windows operating systems that provides services to enable developers to secure Wind… cramer-shoup× 3 Cramer-Shoup asymmetric encryption (an extension of ElGamal) alternating-step× 3 a cryptographic pseudorandom number generator intended to be used in a stream cipher. biclique-attack× 3 feal× 3 a block cipher designed by NTT. It is known to be insecure. diffusion× 3 Diffusion refers to the property of an encryption primitive that small changes in the plaintext result in big changes in the ciphertext and vice-versa. error-propagation× 3 Property of cryptographic primitives to propagate errors. This usually means that an "error" in one block propagates into the following blocks, thereby flipping bits there or completely scrambling tho… mixnets× 3 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… kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. hybrid× 3 Something of mixed origin. In cryptography, typically a cipher system containing both public key and secret key component ciphers, where the public key system is used only to transport the key for the… logjam× 3 An attack on TLS and related protocols as of may 2015. This attack uses pre-computations to attack short prime diffie hellmann key exchange, primes with up to 1024 bits length are considered broken. I… ransomware× 3 plausible-deniability× 3 Plausible deniability may refer $1)$ to deniable encryption schemes allowing to decrypt a ciphertext for a message $m$ to some distinct message $m'$ or $2)$ to a feature provided by deniable file syst… oblivious-ram× 3 a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. onion-routing× 3 A method for anonymous communications over a wide area network such as the Internet. p1363× 3 a set of public key cryptography standards provided by the IEEE. unicity-distance× 3 the average amount of ciphertext a computationally unlimited attacker needs to obtain in order to uniquely determine the correct decryption.
