Multisensory Nature and Mental Health,the required number of shares is lower bound by the algebraic degree of the function being shared plus 1. Defining a correct and incomplete sharing of a function of degree . in . shares is straightforward. However, up to now there is no generic method to achieve uniformity and finding uniform sharin

Gaocun Lv,Hui Wang,Yuchen Shan,Lingguo Zengss attack is feasible on a wide range of benchmarks and SAT-resistant techniques, while incurring minimal run-time and area/delay overhead. Binary decision diagrams (BDDs) are utilized to analyze the proposed bypass attack and assess tradeoffs in security vs overhead of various countermeasures.

Improved Blind Side-Channel Analysis by Exploitation of Joint Distributions of Leakagesrnal value to be correlated to the observed leakages..In this paper we revisit a blind (i.e. leakage-only) attack from Linge et al. that exploits joint distributions of leakages. We show – both by simulations and concrete experiments on a real device – that the maximum likelihood (ML) approach is mo

Convolutional Neural Networks with Data Augmentation Against Jitter-Based Countermeasuresck strategy consists in approximating the information leakages by Gaussian distributions. Nevertheless this approach suffers from the difficulty to deal with both the traces misalignment and the high dimensionality of the data. This forces the attacker to perform critical preprocessing phases, such

CacheZoom: How SGX Amplifies the Power of Cache Attacksd security problems if proper isolation is not enforced. Intel proposed SGX to create a trusted execution environment within the processor. SGX relies on the hardware, and claims runtime protection even if the OS and other software components are malicious. However, SGX disregards side-channel attac

Reconciling , Masking in Hardware and Software attacks. Masking provides high resistance against SCA at an adjustable level of security. A high level of SCA resistance, however, goes hand in hand with an increasing demand for fresh randomness which drastically increases the implementation costs. Since hardware based masking schemes have other s
