It is a cryptographic algorithm used to generate digital signatures, authenticate the sender of a digital message, and prevent message tampering. DSA works by having two keys: a private key owned by the sender and a public key held by the receiver.

WebSep 8, 2024 · In cryptography, confusion refers to making the relationship between ciphertext and the symmetric key as complex as possible. Diffusion is used to dissipate the statistical structure of plaintext over the bulk of ciphertext. What this means is that a single bit change on the plaintext should at least change half of the resulting ciphertext.
