A Key-Management Scheme for Distributed Sensor Networks

by Laurent Eschenauer, Virgil D. Gligor - In Proceedings of the 9th ACM Conference on Computer and Communications Security , 2002
"... Distributed Sensor Networks (DSNs) are ad-hoc mobile networks that include sensor nodes with limited computation and communication capabilities. DSNs are dynamic in the sense that they allow addition and deletion of sensor nodes after deployment to grow the network or replace failing and unreliable ..."

Timing Attacks on Implementations of Diffie-Hellman, RSA, DSS, and Other Systems

by Paul C. Kocher , 1996
"... By carefully measuring the amount of time required to perform private key operations, attackers may be able to find fixed Diffie-Hellman exponents, factor RSA keys, and break other cryptosystems. Against a vulnerable system, the attack is computationally inexpensive and often requires only known cip ..."

Real-Time Dynamic Voltage Scaling for Low-Power Embedded Operating Systems

by Padmanabhan Pillai, Kang G. Shin , 2001
"... In recent years, there has been a rapid and wide spread of nontraditional computing platforms, especially mobile and portable computing devices. As applications become increasingly sophisticated and processing power increases, the most serious limitation on these devices is the available battery lif ..."

life. Dynamic Voltage Scaling (DVS) has been a key technique in exploiting the hardware characteristics of processors to reduce energy dissipation by lowering the supply voltage and operating frequency. The DVS algorithms are shown to be able to make dramatic energy savings while providing

Derivation of Database Keys ’ Operations

by Adio Akinwale, Olusegun Folorunso, Adesina Sodiya
"... Designing normalized relation is subject of great difficult, yet great importance. The paper pre-sented automatic derivation of database keys as a step forward solution to designing normalized relations. It studied relational schema and functional dependencies to derive keys of primary, candidate, a ..."

Tor: The secondgeneration onion router,”

by Roger Dingledine - in 13th USENIX Security Symposium. Usenix, , 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

Chord: A Scalable Peer-to-Peer Lookup Protocol for Internet Applications

by Ion Stoica, Robert Morris, David Liben-Nowell, David R. Karger, M. Frans Kaashoek, Frank Dabek, Hari Balakrishnan - ACM SIGCOMM , 2001
"... A fundamental problem that confronts peer-to-peer applications is the efficient location of the node that stores a desired data item. This paper presents Chord, a distributed lookup protocol that addresses this problem. Chord provides support for just one operation: given a key, it maps the key onto ..."

Differential Power Analysis

by Paul Kocher, Joshua Jaffe, Benjamin Jun , 1999
