Secure Multiparty Computation Using Homomorphic Encryption
Secure multiparty computation has become most popular research now days. Multiple parties want to perform a function with the data possessed by each party without disclosing the data to each other and without the involvement of a trusted third party. This paper deals with the computation of sum of n data items when multiple parties, each having a private data item want to collaboratively compute the sum without disclosing their private data to each other or any other parties. Both Random perturbation and homomorphic encryption techniques are used to accomplish the task.
