Practical encryption  systems  with  new  and  more flexible  capabilities  have  been  enabled  by  recent  advances  in computing  hardware  performance  and  Property  Preserving  En-cryption  (PPE)  schemes.  PPE  schemes  allow  limited  and  pre-selected operations to be performed on encrypted data allowing system   designers   to   trade-off   between   performance,   security and functionality. This paper uses micro-benchmark to evaluate three   interdependent   factors   of   PPE:   performance,   security and   functionality.   The   findings   validate   the   efficacy   of   this technique  and  provide  guidance  to  application  designers  and technology evaluators seeking to understand these interdependent relationships  for  PPE  database  applications.  Experiments  were performed  using  the CryptDB research  system.  Results  validate the  previous  assessments  of CryptDB and  provide  supplementaldetail  on  performance,  security  and  functionality,
