Security Analysis of an Ultra-lightweight RFID Authentication Protocol for M-commerce

Over the last few years, more people perform their social activities on mobile devices, such as mobile payment or mobile wallet. Mobile commerce (m-commerce) refers to manipulating electronic commerce (e-commerce) by using mobile devices and wireless networks. Radio frequency identification(RFID) is a technology which can be employed to complete payment functions on m-commerce. As an RFID subsystem is applied in m-commerce and supply chains, the related security concerns is very important. Recently, Fan et al. have proposed an ultra-lightweight RFID authentication scheme for m-commerce(ULRAS) and claimed that their protocol is enough efficient, and provides a high level of security. In this paper, we show that their protocol is vulnerable to secret disclosure and reader impersonation attacks. Finally, we improve the Fan et al. protocol to present a new one, which is resistant to the mentioned attacks presented in this paper and the other known attacks in the context of RFID authentication. Our proposed improvement does not impose any additional workload on the RFID tag

A Survey of Lightweight Cryptosystems for Smart Home Devices

A Smart Home uses interconnected network technology to monitor the environment, control the various physical appliances, and communicate with each other in a close environment. A typical smart home is made up of a security system, intercommunication system, lighting system, and ventilation system.  Data security schemes for smart homes are ineffective due to inefficiency cryptosystems, high energy consumption, and low exchange security. Traditional cryptosystems are less-applicable because of their large block size, large key size, and complex rounds. This paper conducts a review of smart homes, and adopts Ultra-Sooner Lightweight Cryptography to secure home door. It provides extensive background of cryptography, forms of cryptography as associated issues and strengths, current trends, smart home door system design, and future works suggestions. Specifically, there are prospects of utilizing XORed lightweight cryptosystem for developing encryption and decryption algorithms in smart home devices. The Substitution Permutation Network, and Feistel Network cryptographic primitives were most advanced forms of cipher operations with security guarantees. Therefore, better security, memory and energy efficiency can be obtained with lightweight ciphers in smart home devices when compared to existing solutions. In the subsequent studies, a blockchain-based lightweight cryptography can be the next springboard in attaining the most advanced security for smart home systems and their appliances.     &nbsp

SLEC: A Novel Serverless RFID Authentication Protocol Based on Elliptic Curve Cryptography

Radio Frequency Identification (RFID) is one of the leading technologies in the Internet of Things (IoT) to create an efficient and reliable system to securely identify objects in many environments such as business, health, and manufacturing areas. Since the RFID server, reader, and tag communicate via insecure channels, mutual authentication between the reader and the tag is necessary for secure communication. The central database server supports the authentication of the reader and the tag by storing and managing the network data. Recent lightweight RFID authentication protocols have been proposed to satisfy the security features of RFID communication. A serverless RFID system is a new promising solution to alternate the central database for mobile RFID models. In this model, the reader and the tag perform the mutual authentication without the support of the central database server. However, many security challenges arise from implementing the lightweight RFID authentication protocols in the serverless RFID network. We propose a new robust serverless RFID authentication protocol based on the Elliptic Curve Cryptography (ECC) to prevent the security attacks on the network and maintain the confidentiality and the privacy of the authentication messages and tag information and location. While most of the current protocols assume a secure channel in the setup phase to transmit the communication data, we consider in our protocol an insecure setup phase between the server, reader, and tag to ensure that the data can be renewed from any checkpoint server along with the route of the mobile RFID network. Thus, we implemented the elliptic curve cryptography in the setup phase (renewal phase) to transmit and store the data and the public key of the server to any reader or tag so that the latter can perform the mutual authentication successfully. The proposed model is compared under the classification of the serverless model in term of computation cost and security resistance

RFID-MA XTEA: Cost-Effective RFID-Mutual Authentication Design using XTEA Security on FPGA Platform

RFID systems are one of the essential technologies and used many diverse applications. The security and privacy are the primary concern in RFID systems which are overcome by using suitable authentication protocols. In this manuscript, the cost-effective RFID-Mutual Authentication (MA) using a lightweight Extended Tiny encryption algorithm (XTEA) is designed to overcome the security and privacy issues on Hardware Platform. The proposed design provides two levels of security, which includes secured Tag identification and mutual authentication.  The RFID-MA mainly has Reader and Tag along with the backend Server. It establishes the secured authentication between Tag and Reader using XTEA. The XTEA with Cipher block chaining (CBC) is incorporated in RFID for secured MA purposes. The authentication process completed based on the challenge and response between Reader and Tag using XTEA-CBC. The present work is designed using Verilog-HDL on the Xilinx environment and implemented on Artix-7 FPGA.  The simulation and synthesis results discussed with hardware constraints like Area, power, and time. The present work is compared with existing similar approaches with hardware constraints improvements
