Improved Private Information Download Protocol

Abstract

In this paper, an improved private information down- load protocol will be proposed. The new protocol is more ecient than the well known NetWare version 4 pro- tocol and the recently reported Perlman-Kaufman pro- tocols. More importantly, in order to develop a generic protocol for private information download, no existence of secure trapdoor one-way function, i.e., public-key based encryption/decryption, is assumed for the pro- tocol construction
