An intelligent noise generator that runs as the second hardware thread on the same CPU using should be able to protect the encryption. If the second noise-generation thread is able to randomly stop the encryption thread and do itself some random crypto, it should be able to fool the eavesdropper which will assume that the signals of the noise thread is produced by the encryption thread.

One can also think about modifying the implemenation of OpenSSL and others by inserting a lot of noise in the algorithm itself.

One can also ask chip designers to modify the circuitry to produce a lot of noise during AES instructions. Or do the opposite in circuitry: use something comparable to active noise cancellation in headphones.
