A method for provably secure erasure of data, performed in a memory available to one or more computing devices, comprising the steps of a) 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 said generation being performed interactively between a prover computing device, 'PCD', and a verifier computing device, 'VCD', b) Computing a challenge by said VCD based on said VSI, c) Computing a proof-of-erasure, 'POE', by said PCD based on said PSI and said computed challenge, said POE having a size corresponding to said space-constraint, and d) Verifying by the VCD based on said VSI and said POE.
