WebIn cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers [1] and cryptographic hash functions, wherein if an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip). WebDiffusion is a cryptographic technique invented to increase the redundancy of the plain text to obscure the statistical structure of the plaintext to prevent attempts to deduce the …
