Secure Software Leasing from Standard Assumptions

Understand

Secure software leasing (SSL) is a quantum cryptographic primitive that enables users to execute software only during the software is leased.

• It prevents users from executing leased software after they return the leased software to its owner.
• SSL can make software distribution more flexible and controllable.
• Although SSL is an attractive cryptographic primitive, the existing SSL scheme is based on public key quantum money, which is not instantiated with standard cryptographic assumptions so far.
