The U.S patent system has been under attack for about a decade. One of the main justifications for changing the patent system has centered on the issue of patent quality. According to patent critics, patents are bad or low quality, justifying major changes to the patent examination and review system. I argue that patent quality is a proxy for attacking patent validity, which has a complex histo...

In this paper, the security of a distance bounding protocol is analyzed which has been recently proposed by Jannati and Falahati (so-called JF). We prove that an adversary can recover key bits of JF protocol with probability of “1” while the complexity of attack is “2n” runs of protocol. In addition, we propose an improved protocol and prove that the improved protocol is resistant to mafia frau...

False data injection attack (FDIA) is a critical cyber-attack that can cause disrupt operations and subsequently blackouts in smart grid networks. Cleverly constructed stealthy false measurement vectors circumvent the bad detector unit mislead state estimation process. This article proposes novel belief propagation (BP)-based algorithm to detect both random stealthy-type FDIAs grids with higher...
