“…The requirements of this protocol are modular algebra operations, such as multiplication of matrices, and on-tag PRNG primitives. Based on similar requirements, such as on-tag PRNG and matrix algebra operations, Dolev et al present in [17] two low-overhead proactive unidirectional protocols, called PISP (Proactive Informational Secure Protocol) and PCSP (Proactive Computationally Secure Protocol), with evolving on-tag secrets that expands indefinitely over time. Both PISP and PCSP are compared and contrasted in a joint publication appeared in [19].…”

Abstract. The design and implementation of security threat mitigation mechanisms in RFID systems, specially in low-cost RFID tags, are gaining great attention in both industry and academia. One main focus of research interests is the authentication and privacy techniques to prevent attacks targeting the insecure wireless channel of these systems. Cryptography is a key tool to address these threats. Nevertheless, strong hardware constraints, such as production costs, power consumption, time of response, and regulations compliance, makes the use of traditional cryptography in these systems a very challenging problem. The use of low-overhead procedures becomes the main approach to solve these challenging problems where traditional cryptography cannot fit. Recent results and trends, with an emphasis on lightweight techniques for addressing critical threats against low-cost RFID systems, are surveyed.

“…We see in the use of mutual and proactive evolving predistributed secret schemes (e.g., approaches presented in [25,13]) the most promising candidate for our motivation scenario. These solutions, which mainly rely on the use of on-board pseudo-random number generators, relax the drawbacks detected on the use of hashing functions and environmental values.…”

“…The authors show, indeed, the possibility of a denial-of-service in the strategy presented in [25], and summarized as Protocol 2. An alternative solution, presented in [13], and summarized in Protocol 3, has been reported as computationally secure while still lightweight enough for being implemented in resource-constrained RFID labels.…”

We address security solutions to protect the communication of the wireless components of a home health care system. We analyze especially the problem of exchanging secrets to satisfy authentication of entities. We outline some important aspects that must be guaranteed given the existence of low-cost and resource-constrained RFID components. Appropriate solutions must, therefore, enable several nodes, with different computing and communicating capabilities, to securely interact and communicate.

“…The vector ARV is updated by performing xor of corresponding entries with randomly chosen new n dimensional vector at any communication session. Our work is mostly related to the schemes presented in [6] and filed as patent [7]. In this paper we present here an equivalent solution that maintains only a vector of n numbers instead of O(n 2 ) numbers.…”

We consider repeated communication sessions between a RFID Tag (e.g., Radio Frequency Identification, RFID Tag) and a RFID Verifier. A proactive information theoretic security scheme is proposed. The scheme is based on the assumption that the information exchanged during at least one of every n successive communication sessions is not exposed to an adversary. The Tag and the Verifier maintain a vector of n entries that is repeatedly refreshed by pairwise xoring entries, with a new vector of n entries that is randomly chosen by the Tag and sent to the Verifier as a part of each communication session. The general case in which the adversary does not listen in k ≥ 1 sessions among any n successive communication sessions is also considered. A lower bound of n·(k +1) for the number of random numbers used during any n successive communication sessions is proven. In other words, we prove that an algorithm must use at least n·(k +1) new random numbers during any n successive communication sessions. Then a randomized scheme that uses only O(n log n) new random numbers is presented. A computational secure scheme which is based on the information theoretic secure scheme is used to ensure that even in the case that the adversary listens in all the information exchanges, the communication between the Tag and the Verifier is secure.
