a radio broadcast signal that could easily be recorded and then spoofed by anyone assuming they didn’t just take the device itself off the corpse of a soldier and just use it.

Those issues could be alleviated by having daily codes or a codebook. Similar to how military radios work with loading encryption onto it you could do the same with the GDO.

They have that. The GDO is coded to each team and the codes are only good for a few days. It's in part how they are able to say which team is trying to open the iris.

It should be a constantly updated code operating on an algorithm. Even 24 hours is too long. So much can go wrong in that time and invasions only take a foothold to get started.

[–] Hugin 7 points 10 months ago (1 children)

They never cover it but the codes are probably one time use as well. I remember one of the early episodes SG1 is under tight time constrains because the GDO is going to be locked out soon. I think it's one they recruit Teal'c but I'm not sure.

[–] slazer2au 4 points 10 months ago (1 children)

The first couple episodes they mention that. But I always assumed that meant the codes were on a per mission basis.

Then it doesn't explain Cold Lazuras where jack comes back after everyone or when the evil team came through in the last season to nick the zpm.

I always assumed it worked like an actual garage door opener and had rolling codes.
