In this paper, a novel image encryption scheme based on chaotic maps is proposed. By combining XOR operations and circular bit shift operation, the security of this encryption algorithm is enhanced effectively. Two chaotic maps are adopted in the proposed scheme. One creates a binary stream for XOR operation, and the other creates some random numbers which are used to determine the circular bit shift...
In order to hold the state of the assets accurately in the logistics supply chain, we need to monitor the process of logistics. Radio Frequency Identification (RFID) is a technology to track movement of logistics assets. The importance to logistics tracking system based on RFID, traceability model and method were discussed. Based on the present system and combines RFID, the article proposes a solution...
