I fully expect Phil's voice encryption software to become the de facto telephonic standard just as PGP became the Internet standard. Cogon's Aquafone, while commendable, has the disadvantage of employing DES. I presume Phil will select a more resilient conventional algorithm.

I don't see any reason to believe that triple DES is less secure than other currently popular algorithms such as IDEA, although 3DES does require somewhat more processor power.
