CPA on COLM Authenticated Cipher and the Protection Using Domain-Oriented Masking

Authenticated encryption schemes are important cryptographic primitives that received extensive attention recently. They can provide both confidentiality and authenticity services, simultaneously. Correlation power analysis (CPA) can be a thread for authenticated ciphers, similar to the any physical implementation of any other cryptographic scheme. In this paper, a three-step CPA attack against...

Extended Analysis of Binary Congestion Control

ABSTRACT Congestion ontrol in the Internet relies on binary adjustment algorithms. For example, Transmission Control Proto ol (TCP) in its ongestion avoidan e mode behaves similarly to Additive-In rease Multipli ative-De rease (AIMD) algorithm. The lassi al analysis by Chiu and Jain re ommends AIMD based on the assertion that among stable linear algorithms, AIMD ensures the qui kest onvergen e ...

Threshold Implementation as a Countermeasure against Power Analysis Attacks

One of the usual ways to find sensitive data or secret parameters of cryptographic devices is to use their physical leakages. Power analysis is one of the attacks which lay in such a model. In comparison with other types of side-channels, power analysis is so efficient and has a high success rate. So it is important to provide a countermeasure against it. Different types of countermeasures use ...

Image Enhancement Using an Adaptive Un-sharp Masking Method Considering the Gradient Variation

Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...
