Protecting against Side-channel Attacks: Computing devices leak information to the outside world not just through input-output interaction, but through physical characteristics of computation such as power consumption, timing, and electro-magnetic ...

Abstract. In the past thirty years, cryptology has evolved from a secret art to a modern science. Weaker algorithms and algorithms with short keys are disappearing, political controls of have been reduced, and secure is becoming more and more a commodity. Moreover, implementations are being becoming more secure as well.

plays a significant role in the intelligence mission to both protect sensitive information from disclosure and collect intelligence about the activities of governments and others who pose potential threats to the nation's interests. In an increasingly digital world, more data are encrypted.
