I am implementing secure communication between cloud user and cloud service provider. For secure communication I am using encryption technique.
Dear Vijayh,
I suggest you to see links and attached file on topic.

Try the following paper:

The block cypher itself gives raise to energy efficient algorithms. I would look at the associated algorithms (encryption, decryption).
Find the finite group algebra properties of the block cypher you use, that's where you can optimise.
Optimisation needs to consider two faces:
-authorised user
You want fast algorithms for encrypting and decrypting
-hacker/adversary
You want painful and lengthy algorithms as the only possibility for the adversary.
If your service is bidirectional, with say two people "talking" encryption and decryption might get the same weight in the optimisation criteria.
If your service is very asymmetrical, as in downloading or streaming movies or other contents, the weight is on the decryption (you encode once, you decode maybe millions of times)
