80% of Cell Phone Encryption Solutions Insecure

An anonymous reader writes "Mobile Magazine writes about a blogger named Notrax who has tested 15 methods of secure encryption for mobile phones; out of those he found only 3 could not be cracked at some level. '12 of them were "worthless." It's easy to take the software at face value when it "tells you" that the call is secured. But how does someone actually go about being sure that it is secured? Notrax did some digging and discovered he could break in to almost all of them in under 30 minutes.'" (Above link is to a slightly older description of Notrax's approach; then, it was 9 out of 10 products that were worthless, instead of 12 out of 15.)

      - Most of the the products are "details to be published", including respected software such as Zphone/ZRTP. Just one shines out as both "secure" and "review available". That miracle product is PhoneCrypt. Oooh, I must click on that review now -- oh look at that glowing prose.
