Abstract
A method is described for proving erasure of a memory. In the method a prover device receives a seed value from a verifier device. The prover device generates a series of data blocks starting with the seed value and a function. The series of data blocks is generated using the function and the seed to generate a first data block of the series of data blocks. Each subsequent data block is generated using the function and a preceding data block until a last data block of the series of data blocks is generated and written to the memory portion. The prover device writes the series of data blocks to the memory to overwrite all memory contents of a memory portion of the prover device. After the data blocks are written to the memory by the prover device, the prover device sends notification of memory erasure to the verifier device.
