Breaking and Fixing Anonymous Credentials for the Cloud (Full Version)
Attribute-based credentials Privacy-preserving authentication Strong authentication
2019/9/23
In an attribute-based credential (ABC) system, users obtain a digital certificate on their personal attributes, and can later prove possession of such a certificate in an unlinkable way, thereby selec...
Secure Computation for Cloud data Storage
Multi-party computation semi-trusted cloud data security
2019/6/19
One of the main goals of securing data transmission is focused on the security of cloud data storage. In this paper, we describe several cryptographic techniques which can be used to address the relev...
We develop a new methodology to assess cryptographic key strength using cloud computing, by calculating the true economic cost of (symmetric- or private-) key retrieval for the most common cryptograph...
