Distributing Security-Mediated PKI
The security-mediated approach to PKI offers several advantages, such as instant revocation and compatibility with standard RSA tools. This paper presents a design and prototype that addresses its trust and scalability problems. It uses trusted computing platforms linked with peer-to-peer networks to create a network of trustworthy mediators and improve...

Sizzle: A Standards-Based End-to-End Security Architecture for the Embedded Internet
According to popular perception, public-key cryptography is beyond the capabilities of highly constrained, "mote"-like, embedded devices. This paper shows that elliptic curve cryptography not only makes public-key cryptography feasible on these devices, it allows one to create a complete secure web server stack that runs efficiently within very tight resource...

Energy Analysis of Public-Key Cryptography for Wireless Sensor Networks
In this paper, the energy cost of authentication and key exchange are quantified based on public-key cryptography on an 8-bit microcontroller platform. The paper presents a comparison of two public-key algorithms, RSA and Elliptic Curve Cryptography ECC, and considers mutual authentication and key exchange between two untrusted parties such as...

Threshold-Based Burst Assembly Policies for QoS Support in Optical Burst-Switched Networks
This paper proposes a threshold-based burst assembly scheme in conjunction with a burst segmentation policy to provide QoS in Optical Burst Switched OBS networks. Bursts are assembled at the network edge by collecting packets that have the same QoS requirements. Once the number of packets in a burst reaches a...

Introduction to Public Key Cryptography
The solution to problems of identification, authentication, and privacy in computer-based systems lies in the field of cryptography. Because of the non-physical nature of the medium, traditional methods of physically marking the media with a seal or signature for various business and legal purposes are useless.
