Bellare and Kohno introduced a formal framework for the study of related-key attacks against blockciphers. They established sufficient conditions (output-unpredictability and collision-resistance) on ...
The Security of Abreast-DM in the Ideal Cipher Model

In this paper, we give a security proof for Abreast-DM in
terms of collision resistance, preimage resistance and adaptive preimage
resistance. As old as Tandem-DM, the compression function Abreast-

The Random Oracle Model and the Ideal Cipher Model are two well known idealised
models of computation for proving the security of cryptosystems. At Crypto 2005, Coron et al.
showed that security in ...

The Ideal-Cipher Model of a blockcipher is a well-known and widely-used model
dating back to Shannon [24] and has seen frequent use in proving the security of various
cryptographic objects and proto...
A Practical Limit of Security Proof in the Ideal Cipher Model : Possibility of Using the Constant As a Trapdoor In Several Double Block Length Hash Functions
Hash Function Collision Attack Block Cipher
<
2009/1/9
Recently, Shoichi Hirose [2] proposed several double block
length (DBL) hash functions. Each DBL hash function uses a constant
which has a role to make the DBL hash function collision-resistant in
...
