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.
a term coined by Bruce Schneier to describe products that make fantastic claims about security through cryptography.
a set of public key cryptography standards provided by the IEEE.
an SQL-Aware encrypted database system from MIT
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 symmetric-key block cipher designed by Ron Rivest in 1987.
The Miyaguchi-Preneel scheme, based on a one-way compression function, was proposed around 1989 by Preneel, and independently by Miyaguchi.Ohta, and Iwata.
SHA-3 Competition (2007-2012) was a competition initiated by NIST as a call for a new cryptographic hash algorithm for standardization purposes.
Material related to cryptography and primality tests using Lucas groups.
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.
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…
Scramblers use a secret spreading sequence or secret hop sequence, or some other information that must be kept secret from a potential jammer and/or listener. This mostly assumes sender and receiver t…
for posts that specifically refer to the Secure Hash Standard (SHS), which is published by the NIST (FIPS PUB 180 to FIPS PUB 180.4).
the ability for cryptographic protocols and applications to be configured or upgraded to different algorithms with a minimal of fuss.
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…
RFC 1319 — The MD2 Message-Digest Algorithm is a cryptographic hash function which is no longer considered secure.
a variant of the meet-in-the-middle (MITM) method of cryptanalysis.
a type of side channel attack which exploits sounds emitted by computers or machines.
a secure co-processor found in some PC-type computers that provides cryptographic operations and system integrity measurements.
In a Probabilistic Signature Scheme, the signature depends on a random input, in addition to the private key and message.
a new standard for advanced digital signature by European Directive on a community framework for Electronic Signatures.
should be used for questions that specifically ask about the contents of RFC 7748, Elliptic Curves for Security (January 2016).
For questions regarding practical usage, development, and study of cryptographic schemes and protocols.
a next generation VPN protocol, which lives in the Linux kernel, and uses state of the art cryptography.
a method to construct a one-way compression function from a block cipher.
said to have future-secrecy (or post-compromise security) if compromising the master keys does not allow compromising future sessions. This is a counterpart to forward-secrecy, which is …
part of the SHA-2 family of hash functions with a 224-bit output .
short for “PDF Advanced Electronic Signatures”.
