Elliptic curve hash functions are provided which do not require a pre-existing hash function, such as that required by the MuHash. The elliptic curve hash functions can be built from scratch and are collision free and can be incremental. In one embodiment, rather than a pre-existing hash function, the identity function with padding is used; and in another embodiment, rather than a pre-existing hash function, a block cipher with a fixed non-secret key is used.
