The crypto core is based on the NSK chip, which is a Norwegian design. You are probably right in your assessment that most of the phone itself is Sectra's own design. (Rmz)

Remember, these are the same guys who try to tell people that spread spectrum is "encryption" or at least "secure." Remember that GSM phones and US digital cellphones support encryption. All broken, of course, but it _is_ encryption. In some countries the PTT turns off GSM encryption or forces use of A5/2. In the US, the different cellphone standards support different crypto, and some cell companies or cell sites don't use it. I'll bet $100 to a $1 that if there was a way to find out, we'd find out that the "encrypted telephones" in use in the case in question were not "encryption" as most of the members of this list understand it. Is there enough information in Mr. Marshall's description to be able to associate the FUD with a case and then find out what kind of evidence they present? Thanks!

In this case, the defendants used very sophisticated communications equipment, including use of the Internet, encrypted telephones, and cloned cellular telephones, in what was a vain attempt to avoid detection. But in the end, it was these very devices which led to the devastating evidence against them. Through the use of judicial wiretaps and intercepts in both Colombia and in the United States, their communications were intercepted and recorded, thus producing evidence which comes straight from the defendants' own mouths. I have long doubted the very premise that encrypted communications are a asset to criminals and a threat to law enforcement. The standard way LE penetrates criminal organizations is to work from the bottom. Someone at the retail level is caught and pressured to cooperate. He implicates a superior, and so on. Remember that encrypted messages from the superior to the cooperating underling are sent using the underling's private key. Providing that key to LE is in many ways less risky to the underling than other forms of cooperation. The key need only be provided once and then the is no need for further meeting with agents. Only a few people in LE need to know where the key comes, reducing the risk of leaks and making them easier to trace.. Once they have that key, LE gets both an ongoing clear stream of communications and evidence that is much more damming in court than the traditional hard to hear and obscurely worded wire tap recording.

If Alice and Bob communicate with PK and remailers, as will be expected, how can anything be proved? Sure, if "Pablo Escobar" publishes his public key and signs his messages to "Joe Underling," this may be damning in a court trial. But this scenario is unlikely in the extreme. Were I a felon, as I am, I'd surely take crypto and remailers over the alternative of no crypto and no remailers. --Tim May Y2K: It's not the odds, it's the stakes. -:-:-:-:-:-:-: Timothy C.

Re: DEA says drug smugglers used crypto Net but cops got around it
I used to work for a guy who was an ex NSA man. He had his own company that built crypto phones and sold them world wide. The Saudis bought them as well as a few smaller countries. One time he had guy with " a South American accent" call him to order some phones. He contacted the agency to see if they had any problems They said no problem, send them on. I later asked him why this was ok, since he believed he knew where they were headed. He smiled and told me that he had given they keys to the protocol that he had written (that the phones used) to the Agency some time before. He has been out of the business for some time now. He sold these in the early to mid 80s. So this is old news but it kind of opened my eyes.
