If your original mode of operation is secure, then this should be
secure.
The reduction:
Consider algorithm A that tries to break the double encryption mode of
operation (DM) in the IND-CPA setting. We can construct an algorithm
B that tries to break the original mode of operation (OM)

This is usually the point where I stop reading. Of course 10 orders of
magnitude is ~33 bits, so unless the A5 attacks
