Dear Ian,

On the constructive side you might want to check out NaCl for ARM (best
with NEON), e.g.
	 http://cryptojedi.org/crypto/#neoncrypto
which avoids all software side channel attacks. Not sure how you would
avoid cache attacks in Java.

Cryptographic Research has a demo attacking cell phones running slow
crypto (Java) by electromagnetic radiatiion, see

Attacking fast (good) implementations is a lot harder but wee're looking 
into it. 

All the best
