  • The authors propose a new type of hash
    iterative structure-the ring-iterative structure with feed-
    back which is subdivided into the single feedback ring it-
    eration and the multiple feedback ring iteration, namely
    SFRI and MFRI. Prove that SFRI is at least equivalent to
    the MD structure in security, and MFRI is at least equiv-
    alent to SFRI in security (property 1 makes people incline
    to believe MFRI is more secure than MD). Analyze the
    resistance of MFRI, which results from the joint event on
    message modi¯cation, endless loop on message modi¯ca-
    tion and incompatibility of the su±cient conditions, to the
    multi-block di®erential collision attack. Argue the ine®ec-
    tiveness of the D-way second preimage attack on MFRI.
    Discuss the time and space expenses of MFRI, and point
    out the advantage of MFRI over the tree-iterative struc-
    ture and the zipper-iterative structure.
