Practical Secure Function Evaluation
نویسنده
چکیده
This thesis focuses on the practical aspects of general two-party Secure Function Evaluation (SFE). A new SFE protocol that allows free evaluation of XOR gates and is provably secure against semi-honest adversaries in the random oracle model is given. Furthermore, the extension of SFE to private functions (PF-SFE) using universal circuits is considered. Based on a new practical universal circuit construction, FairplayPF is implemented that extends Fairplay, a well known SFE system, with PF-SFE.

Actively Secure Private Function Evaluation
We propose the first general framework for designing actively secure private function evaluation (PFE), not based on universal circuits. Our framework is naturally divided into pre-processing and online stages and can be instantiated using any generic actively secure multiparty computation (MPC) protocol. Our framework helps address the main open questions about efficiency of actively secure PF...
متن کاملUsing Intel Software Guard Extensions for Efficient Two-Party Secure Function Evaluation
Recent developments have made two-party secure function evaluation (2P-SFE) vastly more efficient. However, due to extensive use of cryptographic operations, these protocols remain too slow for practical use by most applications. The introduction of Intel’s Software Guard Extensions (SGX), which provide an environment for the isolated execution of code and handling of data, offers an opportunit...

The present research sought to determine the impact of mentalization-based therapy on improving the mother-child relationship and secure attachment in children. This quasi-experimental study had a pretest-posttest control group design. The statistical population of the study consisted of all mothers of children aged 3-6 in Parand in 2020. Convenience sampling method was utilized and 30 mothers ...
