Non-Full Sbox Linearization: Applications to Collision Attacks on Round-Reduced Keccak
Keccak SHA-3 hash function
2017/6/8
The Keccak hash function is the winner of the SHA-3 competition and became the SHA-3 standard of NIST in 2015. In this paper, we focus on practical collision attacks against round-reduced Keccak hash ...
A new criterion for avoiding the propagation of linear relations through an Sbox (Full version)
secret-key cryptography / Sbox Boolean function hash functions
2013/4/18
In several cryptographic primitives, Sboxes of small size are used to provide nonlinearity. After several iterations, all the output bits of the primitive are ideally supposed to depend in a nonlinear...
Super-Sbox Cryptanalysis:Improved Attacks for AES-like permutations
hash function cryptanalysis AES
2009/11/18
In this paper, we improve the recent rebound and start-from-the-middle
attacks on AES-like permutations. Our new cryptanalysis technique uses the fact that
one can view two rounds of such permutatio...
文章摘要：
利用直流磁控反应溅射法在不同氧分压下制备了SbOx薄膜，对退火前后薄膜的X射线衍射(XRD)分析表明，退火后薄膜结构发生了从非晶态向晶态的转变。利用示差扫描量热法(DSC)测出不同升温速度条件下非晶态薄膜粉末的晶化峰温度，用Kissinger公式计算了材料的结晶活化能。计算结果表明，随着溅射时氧分压的增加，薄膜的结晶活化能增加，而相应的非晶态与晶...
