The non-repudiation as an essential requirement of many applications can be provided by the asymmetric key model. With the evolution of new applications such as mobile commerce, it...
The public-key model for interactive proofs has proved to be quite effective in improving protocol efficiency [CGGM00]. We argue, however, that its soundness notion is more subtle...
The main results of this work are new public-key encryption schemes that, under the quadratic residuosity (QR) assumption (or Paillier's decisional composite residuosity (DCR...
In STOC 2000, Canetti, Goldreich, Goldwasser, and Micali put forward the strongest notion of zero-knowledge to date, resettable zero-knowledge (RZK) and implemented it in constant ...
In a series of papers Patarin proposes new efficient public key systems. A very interesting proposal, called 2-Round Public Key System with S Boxes, or 2R, is based on the difficul...
