4. 4 How the Cybertrust Community can Benefit Methodology/understanding as useful as actual constructions. Accessible textbooks on modern crypto,eg Katz & Lindell Consult cryptographers when using crypto primitives, doing protocol design. Recognize that going from theory to practice is sometimes a long process.
