Remote block and backpack - operation codes - clearance codes

The remote block in SE1 has a single function that allows a vessel to be controlled.

Could it do more?

In SE1 hostility is set as: enemy - neutral - friend.

Though simple, this limits interactions between entities.

It could be that I am requested to directly deliver a diplomatic package to an enemy, but can not approach due to the hostility status between us.

In other situation it could be that within my own faction I would need security clearance to access a part of my factions base, or use a particular vessel.

This could be especially difficult in multiplayer.

Some posts have suggested key cards or key pad codes, but these would only work for the player, not for a vessel. (I still think that both of these are a good idea.)

So I wondered if it were possible to have operational codes stored in the players backpack and in a remote block to verify more complex access rights, and not get blown out of the sky instantly.

A code would not eliminate the need for hacking, but could be the prize of a hack.

Imagine you find a mysterious old broken drone. You manage to hack its remote block to reveal a code, and then use this to build a new drone that could be used to pass into a base of an ancient alien race.(like Independence day)

Backpack codes could be verified by sensors and remote block codes verified by other remote blocks(may be).

A code could be revoked by acts of destruction or by the use of small arms whereby hostility defaults and the clearance code status of the provocateur is set to enemy.
