SecLib.Ref
Contents
Description
It provides a secure interface for manipulation of references.
- data Ref l a
- newRefSecIO :: a -> SecIO l (Ref l' a)
- readRefSecIO :: Ref l a -> SecIO l' (Sec l a)
- writeRefSecIO :: Ref l a -> a -> SecIO l ()
Secure references
Operations
newRefSecIO :: a -> SecIO l (Ref l' a) Source
It creates a new reference. There is no relation between
l and l' since creating a reference
is not an observable event inside the SecIO monad.
readRefSecIO :: Ref l a -> SecIO l' (Sec l a) Source
As above, there is no relation between
l and l'. Bare in mind that reading a reference
is not an observable event inside the SecIO monad.
writeRefSecIO :: Ref l a -> a -> SecIO l () Source
It writes references only at the security level indicated by the argument
of the SecIO monad.
