Abstract

See full text

A method for provably secure erasure of data, performed in a memory available to one or more computing devices, includes generating prover state information (PSI), verifier state information (VSI), and common reference information (CRI) based on security information, a pregiven time-constraint, and a pregiven space-constraint, the generating PSI, VSI, and CRI being performed interactively between a prover computing device (PCD), and a verifier computing device, (VCD); computing, by the VCD based on the VSI, a challenge; computing a proof-of-erasure (POE) by the PCD based on the PSI and the computed challenge, the POE having a size corresponding to the pregiven space-constraint; and verifying by the VCD based on the VSI and the POE.
