I have two web services A and B the requests between those services is http.
I want so establish a secure connection between service A and service B to ensure the authorized and authenticate request from the source and insure data was not tampered.
My Application running on PHP "service B -the data store (the server)-". My client is service from another side "service B -the client or service A-" and programming language we don't care about because we have HTTP Request.
If there are any server side implementation and concept can and body toll me I will appreciate.
I know SSL, but I am looking for something like OAuth protocol but simpler to implement
