No, it is not. A single block operation takes almost half a second on
NOKIA 3410, which means that encrypting a simple text message takes seconds,

Huh! Are you sure you're using an AES implementation that's optimized
for your platform? You can get an order-of-magnitude improvement by
optimizing the code (or running an assembler version). Obviously there
are time/space tradeoffs to be made as well, but I find it hard to
believe that it takes 500ms for a single block operation even in an
optimized implementation.
