Preimage Attacks on Full-ARIRANG: Analysis of DM-Mode with Middle Feed-Forward,cture technique optimized for ARIRANG that overcomes the use of the feed-forward to the middle. This enables us to find preimages of full steps ARIRANG-256 and ARIRANG-512 with 2. and 2. compression function operations and 2. and 2. amount of memory, respectively. These are the first results breaking the security of ARIRANG as a hash function.

Known-Key Distinguisher on Round-Reduced 3D Block Cipher,sequent attack. We extend the differential trail to 15 rounds and give a known-key distinguisher based on the 15-round differential path. The complexity of finding a right pair is 2., which is clearly lower than the complexity of generic attack.

曲解

Order-Preserving Encryption for Non-uniformly Distributed Plaintexts,LO scheme. Instead of the Euclidean middle range gap, we map the probabilistic middle range gap to a domain gap. Our simulation shows that the proposed method is effective for various distributions and especially for distributions with small variance.

A Map-Layer-Based Access Control Model, Combination Theory is defined here. Then we can overlay the authorization layers to map layers in authorization evaluation, which is more efficient. At last some propagation rules are defined to makes authorization simpler and more flexible. . environment.

Generalized Security Analysis of the Random Key Bits Leakage Attack, same as the case when a fraction of three private RSA keys are leaked. In Takagi’s case, we find that the asymmetricity in two factors of the modulus give some effects on the resistance against the attack.

Biometric Based Secure Communications without Pre-deployed Key for Biosensor Implanted in Body Sensll have transplantation surgery for the secret to be redistributed. In this paper, we proposed the secure communication scheme only using symmetric cryptosystem without a pre-deployed key between a central device and each biosensor in BSNs.
