S. Cheung sccheung@ Received 7 May 2007 Accepted 12 October 2007 Recommended by Stefan Katzenbeisser One of the most important problems facing any distributed application over a heterogeneous network is the protection of private sensitive information in local terminals. A subfield of cryptography called secure multiparty computation SMC is the study of such distributed computation protocols that allow distrusted parties to perform joint computation without disclosing private data. SMC is increasingly used in diverse fields from data mining to computer vision. This paper provides a tutorial on SMC for nonexperts in cryptography and surveys some of the latest advances in this exciting area including various schemes for reducing communication and computation complexity of SMC protocols doubly homomorphic encryption and private information retrieval.

INTRODUCTION The proliferation of capturing and storage devices as well as the ubiquitous presence of computer networks make sharing of data easier than ever. Such pervasive exchange of data however has increasingly raised questions on how sensitive and private information can be .
