I want to protect a Simulink block (subsystem masked) with a password, so that nobody can open the block or modify the initialization parameters included in the mask parameters.
On the other hand, can I protect the m-files I have?

You can protect your Simulink subsystem by one of three methods:
1) Control user access to subsystems
2) Generate an S-function
3) Create a protected model from your subsystem, that can then be referenced from users' models.
You can protect MATLAB-files by using pcode.
