2nd-preimage-resistance× 5
Difficulty of finding another input string that hashes to the same value as a given string

3des× 6
A block cypher encryption algorithm built from applying three iterations of the original DES algorithm.

aes× 190
(or Advanced Encryption Standard), a symmetrical block-cipher algorithm with a 128-bit block size, and key sizes of 128, 192 or 256 bits.

algebraic-attack× 9
a method of cryptanalysis against a cipher
1)expressing the cipher operations as a system of equations.
2)substituting in known data for some of the variables.
3)sol…

algorithm-design× 51
Design of cryptographic primitives (algorithms), like block ciphers, stream ciphers, random-number generators, hash functions, MACs, key exchanges, public-key encryption or signature schemes. Also tag…

authenticated-encryption× 31
Combination of encryption and authentication in a way that ensures confidentiality and integrity.

authentication× 55
successfully validating that an entity you are communicating with is actually who they claim to be. The entity typically demonstrates who they are by showing they possess a secret th…

bitcoin× 13
a digital peer-to-peer currency with no central authority. It was created in 2009 by Satoshi Nakamoto. Transactions are managed entirely by the network.
|
blind-signature× 5
In a blind signature scheme, the signer does not know what he is signing. This is an important building block of anonymous voting or digital cash schemes, because it allows an authority to control the…
|
block-cipher× 116
an encryption algorithm which encrypts fixed-size blocks of plaintext to same-sized blocks of ciphertext. For good ciphers every bit of the ciphertext block depends on every bit of t…

blowfish× 10
an encryption algorithm that can be used as a replacement for the DES or IDEA algorithms. Blowfish was designed in 1993 by Bruce Schneier as an alternative to existing encryption algorithm…
|
blum-blum-shub× 3
a deterministic Pseudo-Random Bit Generator with security demonstrably reducible to that of integer factorization.
|
brute-force-attack× 48
attempting to find a secret value by trying all possible values until the correct one is found.
|

cbc× 51
a method for encrypting large amounts of data with a block cipher that can only encrypt fixed length plaintexts. When used with an unpredictable initialization vector (I…
