A Lightweight Authenticated Encryption Algorithm for RFID Systems
نویسندگان
چکیده
Security of RFID systems is a very important issue with the increasing of their applications. To achieve secure communications between a reader and a tag in RFID systems, encryption of the communication data is usually performed. However, in case of low-cost RFID tags, it is difficult for them to adopt the well-known encryption algorithms because the tags have very limited resources to implement the encryption algorithms. Therefore, in this paper, we propose a new lightweight authenticated symmetric key encryption algorithm for RFID systems which use low-cost tags. To achieve a secure message authentication in the proposed algorithm, redundant bits are contained in a ciphertext. Even though the proposed algorithm uses very lightweight operations for the encryption/decryption, it provides confidentiality, authentication, and integrity.

RSPAE: RFID Search Protocol based on Authenticated Encryption
Search protocols are among the main applications of RFID systems. Since a search protocol should be able to locate a certain tag among many tags, not only it should be secure against RFID threats but also it should be affordable. In this article, an RFID-based search protocol will be presented. We use an encryption technique that is referred to as authenticated encryption in order to boost the ...
متن کاملA Do-It-All-Cipher for RFID: Design Requirements (Extended Abstract)
Recent years have seen significant progress in the development of lightweight symmetric cryptoprimitives. The main concern of the designers of these primitives has been to minimize the number of gate equivalents (GEs) of the hardware implementation. However, there are numerous additional requirements that are present in real-life RFID systems. We give an overview of requirements emerging or alr...

Authenticated encryption algorithms protect both the confidentiality and integrity of messages in a single processing pass. In this note we show how to utilize the L◦P ◦S transform of the Russian GOST R 34.11-2012 standard hash “Streebog” to build an efficient, lightweight algorithm for Authenticated Encryption with Associated Data (AEAD) via the Sponge construction and BLNK padding. The propos...
متن کاملALE: AES-Based Lightweight Authenticated Encryption
In this paper, we propose a new Authenticated Lightweight Encryption algorithm coined ALE. The basic operation of ALE is the AES round transformation and the AES-128 key schedule. ALE is an online single-pass authenticated encryption algorithm that supports optional associated data. Its security relies on using nonces. We provide an optimized low-area implementation of ALE in ASIC hardware and ...
