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.
JSON Web Signatures specify how to encode binary data along with signatures and metadata in RFC 7515.
SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes.
Traitor tracing describes an ability of specific cryptographic schemes that helps trace the source of leaks.
The Miyaguchi-Preneel scheme, based on a one-way compression function, was proposed around 1989 by Preneel, and independently by Miyaguchi.Ohta, and Iwata.
an SQL-Aware encrypted database system from MIT
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…
Unlinkability of two items means that an adversary cannot determine if the items are related. It is often a goal in systems dealing with anonymity and other forms of privacy.
KMAC or Keccak Message Authentication Code is a proposed MAC based on the SHA-3 hash.
a 64-bit block cipher developed by the U.S. National Security Agency (NSA).
a variation of the McEliece Cryptosystem and is equivalent to McEliece from a security point of view, but encryption using Niederreiter is about ten times faster than …
RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure.
a 128-bit block cipher with variable key size of between 128 and 448 bits. It has a heterogeneous structure: several rounds of a cryptographic core are “jacketed” by un-keyed mixing rounds, to…
a family of message authentication codes defined in RFC 4418. UMAC supports 32-, 64-, 96-, and 128-bit tags. UMAC uses a PRF, typically instantiated with AES-128, to expand a short key into …
For questions about design decisions of schemes and implementations of cryptographic primitives to make them resistant to misuse.
a set of public key cryptography standards provided by the IEEE.
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…
a relatively new asymmetric key agreement protocol (also designated the Colored Burau Key Agreement Protocol), based on a simultaneous conjugacy search problem in a braid group.
the art and science of teaching, that is transmitting knowledge. On this website, only the pedagogy of teaching cryptography could possibly be on-topic.
a signature made by multiple parties.
a method to construct a one-way compression function from a block cipher.
