Random but System-Wide Unique Unlinkable Parameters
2012
Journal of Information Security
Preserved Fulltext
But, randomly chosen parameters come with the intrinsic chance of duplicates, which finally may cause cryptographic systems including RSA, ElGamal and Zero-Knowledge proofs to become insecure. ...
When initializing cryptographic systems or running cryptographic protocols, the randomness of critical parameters, like keys or key components, is one of the most crucial aspects. ...
Simply spoken, we will replace random parameters by system-wide unique but random parameters, generated by the use of applicationspecific CFNGs. ...

Various generic ideas and variants on blind signatures have been brought up so far, but few of them considered the randomization property or offered formal proofs. ...
The concept of randomization can form a solution for reducing the threat of coercion or bribery in anonymous electronic voting systems based on blind signatures. ...
The formal proofs for the unlinkability, unforgeability, and randomization properties of the proposed scheme have been provided in this manuscript as well. ...

We introduce and demonstrate the proposed scheme as a non-invertible transform, while proving its effectiveness and ability to meet the requirements of revocability and unlinkability. ...
In our approach, this decomposition assumes an important part, not only in the generation of orthogonal sequences but also in linking each identity to a unique orthogonal code. ...
