The client’s online runtime improvement is, for some of our protocols, almost 1 order of magnitude,

A consulting system for ECG diagnosisHence, this type of scheme seems to resist better than others to key recovery. Motivated by this observation, we prove an interesting result on the rank metric. Namely, that the learning problem with the rank distance is hard for some parameters, thus invalidating a common strategy for reaction atta

David Basin,Jürgen Doser,Torsten Lodderstedtress additional issues, such as receiver privacy (anonymity), static user-set size, and limited encryption. In this work, we aim to tackle this problem by proposing an efficient broadcast encryption scheme, called “anonymous multi-group broadcast encryption”. This primitive achieves faster encryptio

Communication-Efficient Proactive Secret Sharing for Dynamic Groups with Dishonest Majorities and in other previous work, handling them simultaneously (and efficiently) in a single scheme faces non-trivial challenges. SomePSS protocols can handle batching of . secrets, but all of them are for the honest majority setting. The techniques typically used to accomplish such batching decrease the

These two orders are fundamental
