S5 - Privacy-Preserving Computation

S5 – Privacy-Preserving Computation (ended after CROSSING I)


Due to current trends in modern computing paradigms, the amount of sensitive data processed is continuously increasing. In order to protect against large-scale data leaks, this information should be protected in case it is processed on untrusted machines. Recently proposed cryptographic tools like Secure Two-Party Computation (STC) offer a solution: they allow data to be processed while staying encrypted. Project S5 will advance the state of the art of STC in two ways. First, it designs efficient quantum-secure protocols for different application settings; second, it develops efficient SMC solutions in the context of ''Big Data'' applications.
