Each cryptological advance that was made outside the confines of the NSA's Fort Meade complex was met with increasing legislative and judicial resistance. Levy's storytelling acumen tugs the reader along through mathematical and legal hassles that would stop most narratives in their tracks--his words make even the depressingly silly Clipper chip fiasco vibrant. Hardcore privacy nerds will value Crypto as a review of 30 years of wrangling; those readers with less familiarity with the subject will find it a terrific and well-documented launching pad for further research. From notables like Phil Zimmerman to obscure but important figures like James Ellis, Crypto dishes the dirt on folks who know how to keep a secret. --Rob Lightner --This text refers to an out of print or unavailable edition of this title.

Encryption truly is one of the most critical technologies necessary for a smoothly functioning virtual world, and is very much the case that the U.S. Federal Government successfully delayed the general availability of strong encryption for at least a decade. (Future economists may point back to the last two decades of the 20th century and show how this failed government policy was responsible for the loss of U.S. dominance in the high-tech market.)
It would have been easy to take the politically correct road and portray the Feds as being evil conspirators, bent on maintaining their own power and pride at the expense of the entire world. Levy chooses a more balanced approach, depicting the NSA in nearly heroic terms. He is especially sympathetic towards Clint Brooks (a name I did not know), an NSA lifer who developed the key escrow concept as a compromise that would allow widespread public utilization of strong encryption while still allowing law enforcement (and of course, intelligence agencies), the ability to intercept communications under controlled circumstances. If both the NSA and their philosophical opponents are heroes with noble goals, a tragic ending is inevitable, which adds an element of pathos to this triumph of democracy.
As a former software vendor, I've been totally frustrated by both the crypto export laws and by the NSA attitude of "If you only knew what we knew, you wouldn't even ask that question.Read more ›
Overall, it is an interesting (if dry) read, and, at times will add words (a la Neal Stephenson in Cryptonomicon) to your vocabulary. If you are interested in the history of todays debates on cryptography, I recommend it. If you want to know more about cyphers and other code making/breaking, I would recommend something like Simon Singh's "The Code Book."
First, some of the key players "on the outside" are not mentioned; this may well be because most of those who aren't mentioned by now are "insiders." But this results in some of this book being a bit misleading. For example, serious work on cryptanalysis by outsiders, including one piece of work that Admiral Inman, when head of NSA, described as "the most brilliant piece of civilian cryptanalysis since World War II", was already going on by the late 1970s; this had serious national security implications, and helps to explain why NSA was so ambivalent about "outsiders" engaging in *any* crypto research. Overall, although NSA goofed badly several times, I think they managed to keep a more balanced view on the issue than I might have expected. The fact that Levy doesn't mention some of the key "outsider" work suggests to me that he may not have talked with (or at least didn't gain the confidence of) such people as Cipher Deavours and David Kahn, who could have given him perspective on the "outsider" work that he doesn't discuss.
Secondly, I infer that he was unable to get any of the NSA side of the story from NSA itself. This is a pity. It's presumably not Levy's fault; NSA only talks to people it decides to talk to, and then says only what it decides needs to be said. I assume that Levy tried to get information from NSA and failed; I don't know.Read more ›
Levy has interviewed all of the major players: Diffie, Adleman, Chaum, Zimmerman, and others; he's done nearly a decade of research on the subject, and monitored the sci.crypt.* newsgroups. Clearly, this is an authoritative account of the short 30-year history of public key.
The main theme of the book is how the NSA tried to stifle new developments by the researchers, placing secrecy orders and classifying their patents and papers. Throughout the book, as Levy draws out the characters, it's the crypto community vs. the government, until ultimately the cypherpunks win out.
This book doesn't contain a single diagram; no photos, and no equations at all. So if you're looking for a technical introduction to crypto, look elsewhere; this is purely an informally-written account on the people behind the scenes.
Five stars, for what it is; sure, Levy writes with magazine-style prose, but this fits the high-level view he takes on the subject. Most importantly, this volume was exhaustively researched and has the collaboration of all of the key players, which lends Levy's account great credibility.
