The delay with SSH would even be longer. Again, it is plain stupid to assume that you can reach any security improvments on mobile phone (or to a lttle lesser degree on servers) by increasing the key sizes. The security gain is bug bound and not bound to the key size. > Find one with a better battery/more-efficient processor if these sorts > of calculations would really be an issue, compared to the general > radio use of the phone. Radios are very well optimized. CPUs also very energy efficient - but only if they are idle. On most smartphones you can already notice that by playing a Vorbis file compared to playing a MP3 file; the latter use the DSP (instead of the general purpose CPU) and will play a lot more music before charging is required. Right, you may gain a similar battery life boost by using a crypto accelerator - however they are only designed for 2048 bit and I don't know whether they are available on SoCs Salam-Shalom, Werner -- Die Gedanken sind frei.
