Gram – Schmidt Orthogonalization on Encrypted Vectors

  title={Gram – Schmidt Orthogonalization on Encrypted Vectors},
  author={Pierluigi Failla and Mauro Barni},
In this paper we address a privacy preserving version of the well known Gram – Schmidt Orthogonalization procedure. Specifically, we propose a building block for secure multiparty computation, that is able to orthogonalize a set of componentwise encrypted vectors. Our setting is the following: Bob needs to compute this orthogonalization on some vectors encrypted with the public key of Alice. Hence our intent is not to propose a stand-alone protocol to solve a specific scenario or a specific… CONTINUE READING
