Searchable Encryption (SE) enables a user to search over encrypted data, such as data stored in a remote cloud server. Existing certificate-, identity-, and attribute-based SE schemes suffer from certificate management or key escrow limitations. Furthermore, the semi-honest-but-curious cloud may conduct partial search operations and return a fraction of the search results (i.e., incomplete results)...
It is already known that large complete oriented stars (COSs) with intrinsic weights are amplifiers of selection. This paper addresses the evolutionary dynamics on COSs. First, we give the exact formulas for the fixation probabilities on a COS. We then apply these formulas to study some properties of COSs. The obtained results partially reveal the way in which the fixation probabilities are affected...
