62 reviews"Double agents, code-cracking, and covert operations are not just the stuff of action movies or thrillers. Intelligence communities--comprised of spies as well as cryptographers and experts in a variety of other fields--have played significant roles in both past and present wars as well as in determining foreign threats, such as terrorism, to national security. The seemingly mystery-shrouded world of intelligence agencies and the tactics, strategies, and operations associated with them are made accessible to readers through an in-depth look at intelligence agencies around the world as well as the fundamentals of cryptography" --from the publisher.
