This research establishes the first plain-model copy protection for essential cryptographic tools using correlated challenges, removing previous limitations that required independently sampled inputs. By leveraging quantum states to secure computations like encryption and data comparison, the work addresses a fundamental vulnerability in digital rights management where functionality could be duplicated. This advance sets a new standard for security definitions applicable to single-decryptor encryption without relying on specific system assumptions.

Researchers Secure Copy-Protection Using Correlated Challenges

Quantum Zeitgeist17 septembrie 20264 min de cititArticolul și perspectiva sunt în engleză.

Until now, protecting encrypted data demanded independently sampled challenges, a limitation leaving functionality vulnerable to duplication. This work achieves the first plain-model copy protection for essential cryptographic tools like point functions and k-point functions, resolving open questions from EUROCRYPT’26. By defining correlated challenge unclonable puncturable obfuscation, it establishes a new standard in security definitions applicable to single-decryptor encryption.

A new form of copy protection, where security relies only on standard computational assumptions, now extends to point functions, k-point functions and compute-and-compare programs, alongside identical-challenge copy protection for general puncturable functionalities. This advance defines correlated challenge unclonable puncturable obfuscation (UPO), requiring λc average conditional min-entropy in each data point. Amit Behera and colleagues have developed methods to protect computations from unauthorised copying using quantum states, addressing longstanding challenges in implementing core cryptography such as encryption and…
