Definition ∞ An oblivious updateable policy refers to a system where a policy can be updated without revealing the content of the update to the entities that use it. This cryptographic construction allows for changes to access rules or parameters while preserving the privacy of the policy itself. It maintains operational flexibility without exposing sensitive configuration details.
Context ∞ Oblivious updateable policies are particularly relevant in decentralized systems requiring dynamic access control or configurable privacy settings without public disclosure of the policy logic. The current state involves research into practical implementations that balance cryptographic overhead with the need for frequent policy adjustments. This technology holds potential for enhancing privacy in areas like data sharing agreements and confidential smart contract execution on public ledgers.
