The level of security provided by digital rights management functions and cryptographic protocols depend heavily on the security of an embedded secret key. The current practice of...
Abstract—It is challenging to provide authentication to timecritical multicast data, where low end-to-end delay is of crucial importance. Consequently, it requires not only effi...
Abstract--Packet Level Authentication (PLA) is a novel countermeasure against distributed denial-of-service attacks. Each packet sent across a network has a digital signature and p...
The existence of a central security authority is too restrictive for pervasive computing environments. Existing distributed security schemes fail in a pervasive computing environm...
We present the design and evaluation of Passport, a system that allows source addresses to be validated within the network. Passport uses efficient, symmetric-key cryptography to ...
