Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel processing technique is proposed and the wavelet transform is used to eliminate the impact of sp...

Kritik tesisler, bir ülke için yüksek önem düzeyine sahip, herhangi sebeple savaş, terörist saldırı, doğal afetler vb. gibi kendilerine verilecek zarar neticesinde, ülkeyi önemli ölçüde etkileyebilecek tesislerdir. Bu tesislerin korunması problemlerden biridir. Özellikle 11 Eylül 2001’deki ve AB ülkelerinde gerçekleşen terör saldırıları ile birlikte kritik güvenliğine yönelik ABD, gelişmiş diğe...

hypokalemic disease is a disorder in which the amount of serum’ s potassium declines and the patient faces limbs weakness. in this disease, eye muscle and respiratory muscles rarely become involved and death may follow due to respiratory paralysis and heart conducting disturbances. since this disease is treatable and progressive weakness can be prevented, therefore in the study conducted we att...

In this contribution we propose the so-called SVM attack, a profiling based side channel attack, which uses the machine learning algorithm support vector machines (SVM) in order to recover a cryptographic secret. We compare the SVM attack to the template attack by evaluating the number of required traces in the attack phase to achieve a fixed guessing entropy. In order to highlight the benefits...

A new low-complexity approach to intrusion detection called "bottleneck verification" was developed which can find novel attacks with low false alarm rates. Bottleneck verification is a general approach to intrusion detection designed specifically for systems where there are only a few legal "bottleneck" methods to transition to a higher privilege level and where it is relatively easy to determ...
