At the heart of cryptography is creating trust. CyLab researchers are researching state-of-the-art techniques for establishing secure communication between two or more parties in the presence of a growing number of adversaries. Strong, robust cryptography allows us to shop online, manage personal finances, and communicate with one another without worrying about criminals stealing our information.

Deploying cryptographic keys for wireless sensor networks
One of the most important steps in establishing wireless sensor networks is the deployment of cryptographic keys which, if compromised during initial key setup, could leave the network vulnerable and make it possible for attackers to access transmitted data. In response to this dilemma, Carnegie Mellon CyLab researcher Adrian Perrig has developed Message-in-a-Bottle, a user-friendly, secure mechanism for key setup on wireless sensor nodes.
Establishing secure mobile communication
SafeSlinger is the result of research at Carnegie Mellon’s CyLab that resolves a specific security problem: How can we start a trusted relationship between people, on the fly, without people having sophisticated knowledge of security protocols?
