RECENT ADVANCES ON SECURE COMPUTATIONS OUTSOURCING IN CLOUD COMPUTING

One of the popular applications in the age of cloud computing is computation outsourcing which makes cloud computing a very powerful computing paradigm, through which the clients with lack of computational resource can outsource the heavy computation workloads into untrusted cloud servers and use the unlimited computing resources in a pay-per-use manner. Despite these benefits, the outsourcing paradigm also inevitably suffers from some new security challenges due to untrusted cloud servers. The topics covered in this survey include samples of recent advances in the secure computation outsourcing methods and secure challenges in outsourcing computation.
