Error Correction for Physical Unclonable Functions Using Generalized Concatenated Codes

摘要

Physical Unclonable Functions can be used for secure key generation incryptographic applications. It is explained how methods from coding theory mustbe applied in order to ensure reliable key regeneration. Based on previouswork, we show ways how to obtain better results with respect to errorprobability and codeword length. Also, an example based on GeneralizedConcatenated codes is given, which improves upon used coding schemes for PUFs.
