High efficiency ground data transmission... Optimization is affected by optimum clock recovery procedures, multilevel pulse amplitude modulation, single sideband amplitude modulation, transversal filter equalizers, data scrambling, and active compensation for phase instability
Biometric methods for secure communications in body sensor networks: resource-efficient key management and signal-level data scrambling... In this work, we present two complementary approaches which exploit physiological signals to address security issues: (1) a resource-efficient key management system for generating and distributing cryptographic keys to constituent sensors in a BSN; (2) a novel data scrambling method, based on interpolation and random sampling, that is envisioned as a potential alternative to conventional symmetric encryption algorithms for certain types...
On the security of the dekart primitive... According to the author, the circuits described are suitable for data scrambling but also as building blocks for block ciphers....
Address and data scrambling: causes and impact... This paper presents an analysis of address and data scrambling for memory chips, at the layout and at the electrical level....
