摘要: Widespread adoption of RFID technology is being slowed down because increasing public concerns about associated security threats. This paper shows that it possible to enhance the systems by requiring readers perform a computational effort test. Readers must solve cryptographic puzzle - one components Weakly Secret Bit Commitment (WSBC) sent tags obtain static identifier interrogated tag. The method we present based on simple concept already used in applications such as anti-spam or TCP SYN flooding protection, yet original context until now. scheme provides privacy protection while an effective countermeasure against indiscriminate disclosure whole contents large number tags. Then, scrutinize combined use puzzles and distance-bounding protocols. First, classical relatively straight-forward solution presented. Secondly, introduce protocol named Noent, follows new approach reduces drawbacks with WSBC key delegation, whilst gaining all advantages employing protocols certainty distance between tag reader.
