Approaches to Developing Secure Anonymous Systems
IGI Global eBooks · 2012
This chapter summarizes approaches that are adopted in this book to satisfy various requirements of secure anonymous systems listed in the 1st chapter of Section 1. Homomorphic encryption functions are used to calculate functions of data without knowing their individual values, to detect dishonest deletions of data maintained by other entities, and to identify dishonest entities without knowing any secret of honest entities. Commutative encryption functions are also extensively exploited to maintain integrities of data owned by anonymous entities without knowing the data themselves, e.g. to convince entities that only and all data owned by eligible entities are honestly processed without knowing the values of the data or the identities of their owners.
