I hope you do realize that the answer to that question is on this very same page. 's' is the parameter name used by vBulletin for the session hash.

vB3:

PHP Code:

<input type="hidden" name="s" value="$session[sessionhash]" /> 


vB4:

PHP Code:

<input type="hidden" name="s" value="{vb:raw session[sessionhash]}" /> 


In general when dealing with vBulletin you should avoid custom parameters using a single character as vBulletin use many of them as shorthand notations. For example: t for thread, p for post, f for forum, etc..
