A Peer Mutual Authentication Method using PKI on Super Peer based Peer-to-Peer Systems

In this paper, we suggest a strong peer authentication algorithm that authorizes the peer which requests a service usage of the other peer in super peer based P2P network environment. The proposed peer authentication method, at which public key certificate (PKC) and Kerberos authentication mechanism is applied, enables each peer to perform strong mutual authentication in P2P network environment. The peer mutual authentication is performed by getting authentication ticket and verification it by other peer. Also, the lifetime of a ticket can be controlled by the peer providing services according to each service.

A peer mutual authentication method on super peer based peer-to-peer network

In this paper, we suggest a peer authentication method that authorizes the peer which requests the other peer to use a service of it on super peer based peer-to-peer (P2P) network architecture. The proposed peer authentication method, at which one-time session-keys, public key certificate (PKC) and ticket authentication mechanism are applied, enables each peer to perform strong mutual authentication in P2P network. The peer mutual authentication is performed by getting authentication ticket, submitting it to other peer and verification it by the peer. Also, the lifetime of each ticket can be controlled by the peer providing services according to each service.

An E-Commerce Model using Peer-to-peer Technology and Personal Blog

This study is about an e-commerce model for advertisement of products on Internet shopping malls by using consumers personal blog or personal homepage that contain review information of the products. A user can post review or experiences of using a product with pictures or movie clips of it on the users personal blog. After registration of the contents to the e-commerce system with the peer-to-peer (P2P) application, the manager of a Internet shopping mall can search and apply contents on the mall. Consumer will check the contents when he/she want to buy the product on the mall. The owner of the shopping mall could pay some money or cash back points for the using the contents of the blog users. A blog user can also apply the price information of shopping malls to the product review page after searching them through the P2P communication.
