Cryptography is a key element in establishing trust and enabling services the digital world. It represented ways that are not accessible to human users. Hence, humans left out security necessary modern communication protocols many services. A primitive or protocol should be defined reach goal. Beside introduction part this paper represents types of cryptography, algorithm cryptography technique...

We consider a single-cell downlink massive MIMO communication in the presence of an adversary capable of jamming and eavesdropping simultaneously. We show that massive MIMO communication is naturally resilient to no training-phase jamming attack in which the adversary jams only the data communication and eavesdrops both the data communication and the training. Specifically, we show that the sec...

BACKGROUND Adolescence is a key time period for the emergence of psychosocial and mental health difficulties. To promote adolescent adaptive ('resilient') psychosocial functioning (PSF), appropriate conceptualisation and quantification of such functioning and its predictors is a crucial first step. Here, we quantify resilient functioning as the degree to which an individual functions better or ...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

A recent trend in cryptography is to construct cryptosystems that are secure against physical attacks. Such attacks are usually divided into two classes: the leakage attacks in which the adversary obtains some information about the internal state of the machine, and the tampering attacks where the adversary can modify this state. One of the popular tools used to provide tamper-resistance are th...

Secure transmission of messages has been a major goal since ages, for which cryptography is used. Cryptography is a mathematical techniques used for secure communication. Classical cryptography is traditional means that comprises mathematical functions to restrict eavesdropping problem in communication. Quantum cryptography is a new approach towards secure communication which uses phenomenon of...
