>Dave,

> Re your comments on the flaw apparently found in cellular phones:

> We have released the following statement:

> "NSA had no role in the design or selection of the encryption
>algorithm chosen by the Telecommunications Industry Association (TIA).
>NSA also had no role in the design or manufacture of the telephones
>themselves. As we understand the researchers' claim, it appears that
>the algorithm selected and the way it was implemented in the system has
>led to the stated flaws.

>NSA provided the TIA with technical advice on the exportability of these
>devices under U.S. export regulations and processes."
