Minimizing the Two-Round Even-Mansour Cipher
generalized Even-Mansour cipher key-alternating cipher indistinguishability
2016/1/22
The r-round (iterated) Even-Mansour cipher (also known as key-alternating cipher)defines a block cipher from r fixed public n-bit permutations P 1 ,...,P r as follows: given a se-quence of n-bit round...
We study the strength of certain obfuscation techniques used to protect software from reverse engineering and tampering. We show that some common obfuscation methods can be defeated using a fault inje...
The Collision Security of Tandem-DM in the Ideal Cipher Model
Collision Security Tandem-DM Cipher Model
2012/12/3
We prove that Tandem-DM, which is one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resistance in the ide...
360km Field Transmission of 10 Gbit/s Stream Cipher by Quantum Noise for Optical Network
Fiber optics communication Optical security encryption
2015/6/10
Secure optical transmission experiment is demonstrated using a stream cipher by quantum noise. The bit error rates of a 10Gbit/s signal through 360km fiber for authentic receiver and eavesdropper are ...
Hardware Stream Cipher Based on LFSR and Modular Division Circuit
Linear Feedback Shift Register Stream Cipher Filter generator
2010/2/2
Proposal for a secure stream cipher based on Linear
Feedback Shift Registers (LFSR) is presented here. In this method,
shift register structure used for polynomial modular division is
combined with...
