In a cryptographic sense, integrity means unimpaired and complete.

mappings between elliptic curves; it has been proposed as the foundation of a postquantum cryptosystem.

an object-oriented programming language. Java programs are compiled to bytecode and run in a virtual machine (JVM). Java should not be confused with JavaScript; JavaScript is an entirely diff…

a dynamic, object-oriented, prototype-based, weakly typed language commonly used for scripting in web browsers. Despite the name, it is unrelated to the Java programming language and sha…

a key derivation function ([tag:kdf]) that uses a key in the computation.
× 29
a cryptographic hash function designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche.

For questions about Key Encapsulation Mechanisms (KEMs). KEMs are frequentely used in Cryptography to create public key encryption schemes and are a way to formalize a specific subset of hybrid encryp…

In cryptography, a key derivation function (or KDF) derives one or more secret keys from a secret value such as a master key or other known information such as a password or passphrase using a pseudo-…

Key exchange protocols allow two parties to produce a secret session key over a public channel.
× 30
the process of generating keys for cryptographic purposes.
× 11
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.
× 58
Using the same key for more than one purpose, e.g. to encrypt two messages or to encrypt and authenticate a message. Some cryptosystems may be vulnerable to attacks if keys are inappropriately reused.

Key rotation refers to a schedule or process for changing the key material.
× 310
usually secret information used as input to various kinds of cryptographic algorithms, like encryption, signature, MAC, to select the concrete transformation done by the algorithm.
× 17
an algorithm that expands a relatively short master key to a relatively large expanded key for later use in an encryption and decryption algorithm.
× 121
the size measured in bits of the key used in a cryptographic algorithm.
× 7 × 6
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…
× 92
The attacker knows at least one sample of both the plain text and the cipher text.
× 53 × 26
A length extension attack on a hash or message authentication code function, which allows extra information to be added to the input message without changing the output value.
× 43
Linear Feedback Shift Register, a pseudorandom bit generator which can be efficiently implemented in hardware.
