From the hspice manual:
Use the .PROTECT statement to keep models and cell libraries private.
The .UNPROTECT statement restores normal output functions from a .PROTECT statement.

But I am still confused about these two statement,can you explain it in more details?Thanks very much.

Let me show a example for you.

.protect

.lib '018rf.l' tt

.unprotect

After you do spice simulation, your *.lis file will not contain the information of spice model, 018rf.l .

Hence, your *.lis will be smaller before you not yet add these two statement.

YA!!! That's right !!!!!
 

Now I understand that some information between the .protect and .unprotect statement will not print out in the *.lis file,and what is the purpose,just let the output be more readable or confidential?
 

it helps in making ur list file small by remving unnecessary model files from it.

Absolutely right.
It has nothing with confidential since the sourse netlist are not affected by this option.
