PeerShare: A System Secure Distribution of Sensitive Data Among Social Contacts
This addresses the need for secure data sharing in social networks for users and developers, but it is incremental as it builds on existing social network interfaces.
The authors tackled the problem of securely distributing sensitive data among social contacts by designing and implementing PeerShare, a system that provides authenticity and confidentiality guarantees for applications like shared keys and public keys, and they have already used it in three different applications.
We present the design and implementation of the PeerShare, a system that can be used by applications to securely distribute sensitive data to social contacts of a user. PeerShare incorporates a generic framework that allows different applications to distribute data with different security requirements. By using interfaces available from existing popular social networks. PeerShare is designed to be easy to use for both end users as well as developers of applications. PeerShare can be used to distribute shared keys, public keys and any other data that need to be distributed with authenticity and confidentiality guarantees to an authorized set of recipients, specified in terms of social relationships. We have used \peershare already in three different applications and plan to make it available for developers.
