Significance of Privacy and Security in ICT: A Case study using Secure Multi-Party Computation for Preserving Privacy

Privacy and Security are hot and complicated topics in the modern society within which we live. Information and Communication Technology (ICT) have always been accompanied with security and privacy techniques. Security ensures protection of data of parties in the eco system from unauthorised access and privacy lets the information to be computed and transmitted such that it seems unintelligible to any unauthorised person. Traditionally, these goals have been achieved using private and public key cryptography. A novel scenario in which many parties want to jointly compute some function of their input data without disclosing this private data is considered by many researchers.
