Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a block-cipher-based hashing scheme suitable for
resource constrained devices.
It uses the Lesamnta-LW compression function mode and the MDP domain
extension.
Then, this paper provides provable security analyses of the proposed
scheme.
It is shown that the proposed scheme is both collision-resistant and
preimage-resistant up to the birthday bound in the ideal cipher model.
It is also shown that the proposed scheme in the keyed-via-IV mode is a
pseudorandom function if the underlying block cipher is a pseudorandom
permutation.
These results imply that the proposed scheme has the same level of
security as the original Lesamnta-LW hashing scheme.
Unlike the original Lesamnta-LW hashing scheme, the keyed-via-IV mode of
the proposed scheme does not require output truncation.
This property is useful when the proposed scheme is used for
pseudorandom bit generation.
