Limits of Black-Box Anamorphic Encryptionre secret decryption keys are under the control of a dictator. The challenge here is to be able to establish a secret communication channel to exchange covert (i.e. anamorphic) messages on top of some already deployed public key encryption scheme..Over the last few years several works addressed this

Public-Key Anamorphism in (CCA-Secure) Public-Key Encryption and Beyondt the receiver’s private key and even dictates messages to the sender, cannot prevent the receiver from getting an additional covert anamorphic message from a sender. The model required an initial private collaboration to share some secret. There may be settings though where an initial collaboration

,Zur Pluralität und Methodenvielfalt, .-SUM and its variant .-XOR, especially their . versions, where a random solution is planted in a randomly generated instance and has to be recovered. We provide evidence for the hardness of these problems and show applications to constructing public-key encryption schemes. Our contributions are summarized below.

Remarkably, our design requires only a single challenge, irrespective of the number of files, ensuring both prover’s and verifier’s run-times remain manageable even as file counts soar. Our approach introduces a paradigm shift in PoRep designs, offering a blueprint for highly scalable and efficient decentralized storage solutions.
