....file. In their system, each peer is given a global reputation that reflects the experiences of other peers with it. 3.2 Storage of Peputation Information OpenPrivacy In OpenPrivacy, the reputation information is stored in a cer tificate. The system is similar in concept to web of trust [14]. A peer certifies another peer through the use of certificate. Every certificate stores the value of the target s reputation and the confidence of the certificate creator. To prevent tampering, each certificate is digitally signed with the private key of the certifi cate creator. These ....

The most widely used decentralized trust inference scheme is probably the PGP web of trust [18], which allows NICE is a recursive acronym for NICE is the Internet Cooperative Environment (See http: www.cs.umd.edu projects nice) one level of inference.

....implicitly assumes that all participants are equally willing to share the communal data load, which may not be true in many p2p systems [4] Such a system is also vulnerable to DoS attacks, as there is no preventative measure from inserting arbitrary amounts of complaints into the system. PGP [18] is another distributed trust model that focuses on proving the identity of key holders. PGP uses user defined thresholds to decide whether a given key is trusted or not, and different introducers can be trusted at finite set of different trust levels. Unlike NICE, trust in PGP is only followed ....

Centralized solutions do not scale in open systems, since malicious users can overwhelm the central trust server with spurious transactions. The most widely used decentralized trust inference scheme is probably the PGP web of trust [18], which allows one level of inference. We present a new decentralized trust inference scheme that can be used to infer across arbitrary levels of trust. There is no trust third partyor centralized repository of trust information in our scheme. Users in our system only store information they ....

....PGP. 1 Introduction Public key cryptography has recently become the focus of public attention as governments in and outside the U.S. try to regulate information flow on the Internet. What is public key cryptography about The following concise explanation from Phil Zimmermann can be found in [1] Pretty Good(tm) Privacy (PGP) from Phil s Pretty Good Software, is a high security cryptographic software application for MSDOS, Unix, VAX VMS, and other computers. PGP allows people to exchange files or messages with privacy, authentication, and convenience. Privacy means that only those ....
