One-way Hash Function Construction Based on Hènon-like Mapping |
| |
Abstract: | Based on chaotic theory and one-way hash function character, it is presented to construct a one-way hash function algorithm with Henon-like mapping and discussed security of algorithm. It is sensitive to initial conditions and irreversible, we can produce 256 bits one-way Hash for the initial information. Message digest of the plaintext can be produced easily and then to produce digital signature. |
