Number encryption algorithm : <p>I have a list of numbers. I will be calling a service(let's say accountant service) which is going to perform some operation on these list of numbers and will return me the final result.</p>

<p>I don't want to pass my data in plain format. I want to encrypt numbers in such a way if service performs any arithmetic operation and return me the result, I will be able to decrypt it back with actual result.</p>
