How to securly share files within a local network
 

My setup is simple. I have a router that is connected to the Internet via a phone socket (ADSL). In addition, I have two computers which connect wirelessly to the router. Both computers are running Linux Mint (no other operating systems are involved).

I would like to share files between my two computers. One use of this would be, for example, to view on computer B, a video file that is stored on computer A. Or at least to be able to copy the file over, without using a memory stick, and then watch it locally.

I'm not sure whether computer A and B can 'talk' directly with each other, or whether the router needs to be involved in the process.

Another important aspect is I do not want to compromise the security of my network. I want computer A and B to share files between them but not to any other computer.

Could someone please point me in the right direction?

My ideas on this.

Self signed certificate to authenticate.
sftp or ftps

ssh

Security from who? Other users on those two computers? Other computers on your local network? The outside world? Depending on who you want to protect this file sharing from, the approach might differ.

Another option for secure sharing is sshfs.
