WebMar 11, 2024 · Cryptography helps protect data from being viewed, provides ways to detect whether data has been modified, and helps provide a secure means of communication over otherwise nonsecure channels. For example, data can be encrypted by using a cryptographic algorithm, transmitted in an encrypted state, and later decrypted by the intended party. WebThis paper proposes a new hash construction based on the widely used Merkle-Damgård (MD) iteration [13,9]. It achieves the three basic properties required from a cryptographic hash function: collision (Coll), second preimage (Sec) and preimage (Pre) security. We show property preservation for the first two properties in the standard security ...
