Blocker tags are initially introduced to protect regular tags in certain ID ranges, called blocking ranges, from unwanted scanning in RFID systems. But if misused, blocker tags can cause blocking attacks that corrupt the communication between interfered regular tags and readers. Previous approaches can only detect blocking behavior. However, they cannot distinguish malicious blocking from legitimate...
In mobile ad hoc networks (MANETs), identity (ID)-based cryptography with threshold secret sharing is a popular approach for the key management design. Most previous work for key management in MANETs concentrates on the protocols and structures. How to optimally conduct node selection in ID-based cryptography with threshold secret sharing merits further investigation. In this paper, we propose a distributed...
