“…The commonly used hash functions like Message-Digest Algorithm 5 (MD5) and Secure Hash Algorithm 256 (SHA-256) need 8,001 and 10,868 logical gates, respectively [15]. Fortunately, several lightweight hash functions, such as SPONGENT [16], PHOTON [17], Quark [18] and LHash [19], have been introduced, which are able to provide suitable security primitives for resource constrained RFID devices. For instance, the implementation cost of 96-bit LHash is just 817 logical gates [19].…”

In recent years, radio frequency identification (RFID) technology has been applied to construct better healthcare systems, offering various healthcare services that can benefit all medical staff and patients. However, because of the insecure communication channels in RFID systems, security is a main concern to be solved for RFID to be used in healthcare systems. To address this issue, recently in 2019, Safkhani et al. proposed a lightweight RFID authentication protocol in IEEE Access. The authors claimed that their protocol has a higher security level than existing protocols in this category. This article firstly analyzes the security of Safkhani et al.'s protocol, and shows that this protocol is lack of forward secrecy and scalability. Then, a new and secure mutual authentication protocol (SecMAP) is proposed to overcome these weaknesses. The security of the SecMAP protocol is confirmed with formal analyses using the Gong-Needham-Yahalom (GNY) logic and the Scyther tool. Besides, SecMAP is compatible with low-cost RFID tags. Thus, the proposed protocol can effectively provide security for RFID based healthcare systems.

Abstract. In this paper, we propose a new Cellular Automata (CA) based scalable parameterized hash function family named CASH. The construction of CASH is inspired by sponge function and the internal round transformation employs linear CA. For the first time, we have managed to merge the classical add-round-constant and subsequent diffusion layers. The primitive function of CASH family is proved to be secure against the state-of-the-art attacks. All the designs are implemented on Xilinx Virtex-6 FPGAs and compared with the best reported results in literature. The results show that CASH outperforms the SHA-3 finalists with respect to throughput and throughput/area.
