Class BooleanPolicy

java.lang.Object

org.cryptimeleon.craco.common.policies.BooleanPolicy

All Implemented Interfaces:

Policy, CiphertextIndex, KeyIndex, org.cryptimeleon.math.hash.UniqueByteRepresentable, org.cryptimeleon.math.serialization.Representable, org.cryptimeleon.math.serialization.StandaloneRepresentable

public class BooleanPolicy
extends java.lang.Object
implements Policy

A Boolean policy consists of a Boolean operator and a set of policies.

To fulfill a Boolean policy,

• all the contained policies must be fulfilled in case of an AND operator,
• one of the contained policies must be fulfilled in case of an OR operator.
