where ɛ is a small number. The synchrosqueezed transform produces narrow ridges compared to the windowed short-time Fourier transform. However, the width of the short-time transform still affects the ability of the synchrosqueezed transform to separate modes. To be resolvable, the modes must obey...
More- over, the term e contains information about the original plaintext and therefore, to ensure private puncturing, we must somehow allow for correct computation without revealing the actual value of e. Resolving this issue seems difficult. It is precisely the reason why the predicate encryption...
