Second Preimage Analysis of Whirlwind
[chapter]
2015
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we evaluate the second preimage resistance of the Whirlwind hash function. ...
Finally, by adopting another meet in the middle attack, we are able to generate n-block message second preimages of the 5 and 6-round reduced hash function with time complexity of 2 449 and 2 505 and memory ...
The authors would like to thank the anonymous reviewers for their valuable comments and suggestions that helped improve the quality of the paper. ...

Maelstrom-0 is the second member of a family of AES-based hash functions whose designs are pioneered by Paulo Baretto and Vincent Rijmen. ...
Using our approach, preimages of the 6-round reduced Maelstrom-0 hash function are generated with time complexity of 2 505 and memory complexity of 2 112 . ...

We claim the algorithm fulfils all the basic properties such as preimage resistance, collision resistance of a one-way unkeyed hash function. ...
Finally the comparative usability of the hash algorithm in the said application domain is worked out and that shows the dominance of our scheme over two of the state-of-the-art hashing schemes. ...
In security analysis, they have shown that the signature scheme is preimage and second preimage resistant. ...
