Identity-Based Cryptography
Public-key certificates are the main tool for authentication of users and devices in digital world. Certificate management is a complex, inefficient and error-prone task. Identity-based cryptography, proposed in 1984, uses users' identifiers such as their email address, as their public key. This significantly reduces the complexity of the system and the cost for establishing and managing the public key based authentication framework, also known as Public Key Infrastructure (PKI).
In this talk, we give an overview of identity-based cryptography and discuss its advantages and disadvantages. We also give an overview of our recent work in this line of research.

Challenges for future firewalls
A firewall is a system that provides at a minimum an access control facility for network services. More sophisticated firewalls can detect and remove attacks or undesirable protocol elements from the data stream.
This talk presents an overview of common firewall technologies and outlines a number of challenges facing firewalls because of recent advances in computer and communication technologies.
