Evaluating the indistinguishability of the XTS mode in the proposed security model
block cipher XTS indistinguishability
2018/2/3
In this paper, we consider the indistinguishability of XTS in some security models for both full final block and partial final block cases. Firstly, some evaluations of the indistinguishability up-to-...
Evaluating web PKIs
PKI severely broken
2017/6/6
Certificate authorities serve as trusted parties to help secure web communications. They are a vital component for ensuring the security of cloud infrastructures and big data repositories. Unfortunate...

Double DIP: Re-Evaluating Security of Logic Encryption Algorithms
logic encryption circuit obfuscation
2017/4/5
Logic encryption is a hardware security technique that uses extra key inputs to lock a given combinational circuit. A recent study by Subramanyan et al. shows that all existing logic encryption techni...
Evaluating Entropy for TRNGs: Efficient, Robust and Provably Secure
online entropy estimators testable random number generators true random number generators in changing environments
2016/12/7
Estimating entropy of randomness sources is a task of crit- ical importance in the context of true random number generators, as feeding cryptographic applications with insufficient entropy is a seriou...
Analysis of ARX Functions: Pseudo-linear Methods for Approximation, Differentials, and Evaluating Diffusion
ARX block ciphers hash functions
2016/1/6
This paper explores the approximation of addition mod 2n
by addition mod 2w, where
1 ≤ w ≤ n, in ARX functions that use large words (e.g., 32-bit words or 64-bit words). Three main areas
are explor...
Evaluating the Duplication of Dual-Rail Precharge Logics on FPGAs
side-channel analysis countermeasure FPGA
2016/1/3
Power-equalization schemes for digital circuits aim to harden
cryptographic designs against power analysis attacks. With respect to
dual-rail logics most of these schemes have originally been design...
Success through confidence: Evaluating the effectiveness of a side-channel attack
Side-channel attacks divide-and-conquer strategy
2015/12/31
Side-channel attacks usually apply a divide-and-conquer strategy,
separately recovering different parts of the secret. Their efficiency in
practice relies on the adversary ability to precisely asses...
Characterizing NTRU-Variants Using Group Ring and Evaluating their Lattice Security
NTRU lattice-based cryptography group ring
2015/12/18
The encryption scheme NTRU is designed over a quotient ring of a polynomial
ring. Basically, if the ring is changed to any other ring, NTRU-like cryptosystem
is constructible.
On Evaluating Circuits with Inputs Encrypted by Different Fully Homomorphic Encryption Schemes
Fully Homomorphic Encryption Multi-Scheme FHE Trivial Encryptions Ciphertext Trees Multiparty Computations
2013/4/18
We consider the problem of evaluating circuits whose inputs are encrypted with possibly different encryption schemes. Let $\mathcal{C}$ be any circuit with input $x_1, \dots, x_t \in \{0,1\}$, and let...
Evaluating Security of Voting Schemes in the Universal Composability Framework
Voting homomorphic threshold encryption universal composability
2009/4/13
In the literature, voting protocols are considered secure if they satisfy requirements
such as privacy, accuracy, robustness, etc. It can be time consuming to evaluate a voting
protocol with respect...
Evaluating elliptic curve based KEMs in the light of pairings
public-key cryptography key encapsulation mechanisms pairings
2009/3/25
Several efforts have been made recently to put forward a set of cryptographic
primitives for public key encryption, suitable to be standardized. In two of them
(in the first place the NESSIE europea...
