Secure communication between peers: SSL through JSSE
Secure communication between peers: SSL through JSSE
A core requirement of any non-trivial P2P application is secure communication between peers. While the details of the security depend on how the application will be used and on what it will protect, it's often possible to implement strong, general-purpose security using off-the-shelf technology such as SSL. This article demonstrates how to use SSL (via JSSE) in P2P security.

A three-pronged solution for identifying users
A three-pronged solution for identifying users
The problem of system security starts with discovering the identity of the user on the other end of the communications link. This article discusses three familiar approaches for identifying users, highlights their strengths and weaknesses (alone and in combinations), and provides some examples of each.
