Efficient Message Authentication Codes with Combinatorial Group Testing
Message authentication code Combinatorial group testing Data corruption
2019/4/23
Message authentication code, MAC for short, is a symmetric-key cryptographic function for authenticity. A standard MAC verification only tells whether the message is valid or invalid, and thus we can ...
Non-adaptive Group-Testing Aggregate MAC Scheme
message authentication aggregate group testing
2018/5/22
This paper applies non-adaptive group testing to aggregate message authentication code (MAC) and introduces non-adaptive group-testing aggregate MAC. After formalization of its syntax and security req...
Tally-based simple decoders for traitor tracing and group testing
traitor tracing Tardos code collusion
2016/1/6
In this paper we construct a score system from the Neyman-Pearson hypothesis test (which is known to be the most powerful test possible) into which we feed all the evidence available to the tracer, in...
Generalised tally-based decoders for traitor tracing and group testing
traitor tracing group testing fingerprinting
2015/12/29
We propose a new type of score function for Tardos traitor tracing codes. It is related to the recently introduced tally-based score function, but it utilizes more of the information available to the ...
Efficient detection of integrity violations is crucial for the reliability of both data at rest and data in transit. While ideally one would want to always find all changes in the input data, in pract...
We observe that finding invalid signatures in batches of signatures that fail batch verification
is an instance of the classical group testing problem. We present and compare new sequential
and para...
