cryptographic attack
attack aimed at circumventing the security of a cryptographic system
man-in-the-middle attack
form of active eavesdropping in which the attacker makes connections with the victims and relays messages between them
linear cryptanalysis
general form of cryptanalysis based on finding affine approximations to the action of a cipher
side-channel attack
any attack based on information gained from the implementation of a computer system
Rotational cryptanalysis
Cryptography term
harvest now, decrypt later
surveillance strategy
frequency analysis
study of the frequency of letters or groups of letters in a ciphertext
distinguishing attack
cryptographic attack that distinguishes a ciphertext from truly random data
stream cipher attack
Methods to break a stream cipher
downgrade attack
cryptographic attack that forces the use of weaker or no encryption
cube attack
method of cryptanalysis
differential cryptanalysis
general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions
collision attack
cryptographic attack
Watermarking attack
attack on disk encryption methods
padding oracle attack
attack which uses the padding validation of a cryptographic message to decrypt the ciphertext
length extension attack
attack against cryptographical hash functions, where knowing Hash(message₁) and the length of message₁ allows an attacker to calculate Hash(message₁ ‖ message₂) for an attacker-controlled message₂
birthday attack
type of cryptographic attack
brute-force attack
cryptanalytic method for unauthorized users to access data via an exhaustive search
meet-in-the-middle attack
cryptographic attack against encryption schemes that rely on performing multiple encryption operations in sequence
meet-in-the-middle attack
cryptographic attack against encryption schemes that rely on performing multiple encryption operations in sequence
reflection attack
method of attacking a challenge-response authentication system that uses the same protocol in both directions
bit-flipping attack
cryptographic attack
