 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. hard-core-predicate× 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. desx× 3 an extension of DES that attempts to foil brute force attacks 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… kbkdf× 3 a key derivation function ([tag:kdf]) that uses a key in the computation. 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… monotone-access-structure× 3 Let $\Omega$ be a set of entities. An *access structure* $\mathcal{A}$ is a collection of nonempty subsets of the power set $P(\mathcal{A})$. This structure is called *monotone*, if $A\in\mathcal{A}$ … 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… predicate-encryption× 3 an encryption paradigm which gives a master secret key owner fine-grained control over access to encrypted data. oblivious-ram× 3 a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. p1363× 3 a set of public key cryptography standards provided by the IEEE. onion-routing× 3 A method for anonymous communications over a wide area network such as the Internet. present× 2 a lightweight block cipher with a 64-bit block size and an 80 or 128 bit key. random× 2 miyaguchi-preneel× 2 The Miyaguchi-Preneel scheme, based on a one-way compression function, was proposed around 1989 by Preneel, and independently by Miyaguchi.Ohta, and Iwata. lucas× 2 differential-privacy× 2 hermitian-curves× 2 hashed-elgamal× 2 arx× 2 Design philosophy for ciphers. ARX solely relies on additions, rotations and XORs to build ciphers and similar algorithms. This usually constructs ciphers that are highly resistant against side-channe… xml-encryption× 2 Encryption of data represented in XML according to the W3C Specification. voip× 2 a technology that allows telephone calls to be made over computer networks like the Internet. threefish× 2 A family of tweakable symmetric block-cipher algorithms with 256, 512 and 1024 bit block and key sizes. subsetsum× 2 tokenization× 2 the process of breaking a stream of text up into words, phrases, symbols, or other meaningful elements called tokens. secure-index× 2 skipjack× 2 a 64-bit block cipher developed by the U.S. National Security Agency (NSA). shacal-2 Blockcipher based on the compression function of SHA-256. This cipher interprets the internal compression function of SHA-256 as blockcipher. The key is provided as "input data" and the input is fed i… sha-3-competition SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes. rsap a variant of RSA, meant to increase the RSA public modulus size while keeping computation cost moderate. traitor-tracing Traitor tracing describes an ability of specific cryptographic schemes that helps trace the source of leaks. sstp a VPN tunneling protocol that allows the tunneling of PPP or L2TP traffic over an SSL connection. vm-reset
