man-in-the-middle

I have a C++ client/server application where the client and server are my executable. Each time a connection is made between the client and server, I generate a new encryption key for that session and I wish to transmit this session key and encrypt this session key using a static key that is built into both the client and server.

However, running strings on my executable reveals the static key.

How can I hide the embedded static key in my client and server application so that they are not easily extracted and thus allowing someone to decode my session key.
