Fault Injection and a Timing Channel on an Analysis Technique [PDF]

open access: yes, 2002
Attacks on cryptosystem implementations (e.g. security fault injection, timing analysis and differential power analysis) are amongst the most exciting developments in cryptanalysis of the past decade. Altering the internal state of a cryptosystem or profiling the system's computational dynamics can be used to gain a huge amount of information.

Significance of the injection timing of ephedrine to reduce the onset time of rocuronium [PDF]

open access: yesAnaesthesia, 2008
Summary We postulated that the onset time of rocuronium can be accelerated effectively if it is administered at the time when the effect of ephedrine on cardiac output has reached its maximum. Seventy‐five male, anaesthetised, patients were randomly allocated to three groups. Ephedrine 70 μg.kg
