sql table referential integrity

So i have table A (keyed by identity column), and index A (keyed by key1,
key2).

I have table B (keyed by identity column) and index B (keyed by key1, key2
- same defined keys as in index A)

table B is really just an "additional information" table for the rows and
keys defined in table A.

How can I apply some kind of referential integrity over table B to allow
table B keyed rows to be deleted if table A similar keyed rows are
deleted? Likewise if table A key value changes, table B key values change.

I know I am probably dreaming. I just don't want to go handle this stuff
programmatically.
