When embedding cryptographic tools in actual computing systems, it is important to ensure physical layer protection to cryptographic keys. A simple risk analysis shows that taking advantage of system (i.e., hardware, software, network) vulnerabilities ...

Enhancing user privacy while allowing the use of digital credentials in network-wide applications is a very active area. Group signatures are primary privacy-preserving credentials that enable both, non-repudiation and abuser-tracing.

When embedding ...
