On the one hand, compilers for secure computation protocols, such as FairPlay or FairPlayMP, have significantly simplified the development of such protocols. On the other hand, ...
We present a cryptographic framework to achieve access control, privacy of social relations, secrecy of resources, and anonymity of users in social networks. The main idea is to u...
Despite the increased focus on security, critical information systems remain vulnerable to cyber attacks. The trend lends importance to the concept of intrusion tolerance: there is...
A cooperative structured peer-to-peer file-sharing system requires that the nodes participating in the system need to maintain the location mappings of other nodes. However, the s...
Although cryptographic algorithms are designed to resist at least thousands of years of cryptoanalysis, implementing them with either software or hardware usually leaks additional...
