An Efficient Single-Slow-Phase Mutually Authenticated RFID Distance Bounding Protocol with Tag Privacy [chapter]

Anjia Yang, Yunhui Zhuang, Duncan S. Wong
2012 Lecture Notes in Computer Science  
The new protocol requires the tag to evaluate a PRF function for two times only, rather than three times as in one of the most efficient mutually authenticated RFID distance bounding protocols currently  ...  Due to the requirements of being lightweight, low-cost, and efficient, it is the common objective to design new RFID distance bounding protocols which require fewer message flows and less complex cryptographic  ...  Finally, the efficiency of a distance bounding protocol is an important concern of RFID technology, due to the tag's limited computation and storage capacities.  ...

2018 ACM Computing Surveys  
Distance bounding protocols allow a verifier to both authenticate a prover and evaluate whether the latter is located in his vicinity.  ...  This survey analyzes and compares in a unified manner many existing distance bounding protocols with respect to several key security and complexity features.  ...  This is the worst case scenario. The success probability of an attacker depends on . This often makes the analysis more complex and the comparison of various distance-bounding protocols difficult.  ...

Probabilistic communication complexity

1986 Journal of computer and system sciences (Print)  
The upper bounds which we obtained for the functions-quality and verification of Hamming distance-are considerably better than their counterparts in the deterministic, the nondeterministic, and the bounded  ...  Communication is a bottleneck in many distributed computations. In VLSI, communication constraints dictate lower bounds on the performance of chips.  ...  The efftcient protocol for the verilication of Hamming distance is suggested by P.

2010 2010 IEEE 51st Annual Symposium on Foundations of Computer Science  
Our results imply almost tight lower bounds on the accuracy of such data analyses, both for specific natural functions (such as Hamming distance) and in general.  ...  In addition, those bounds demonstrate a dramatic gap between the accuracy that can be obtained by differentially private data analysis versus the accuracy obtainable when privacy is relaxed to a computational  ...  We note that the connection between differential-privacy and communication complexity can be used to prove lower bounds on the error in computing specific functions for which lower bounds on the communication  ...
