Sector key related with UID

It's possible to create uniq KeyA/B for each Card

Read Card UID
Select correct key from database
Read/Write using UID_related KeyA/B

It's possible not to use Database but some algorithms

where f(UID+key) = KeyA

Is this way was been detected somewhere?
what kind of algorithm was used for that?
