Description
We revisit the problem of “sending information into the future” by proposing an anonymous, non-interactive, server-based Timed-Release Encryption (TRE) protocol. We improve upon recent approaches by Blake and Chan, Hwang et al., and Cathalo et al., by reducing the number of bilinear pairings that users must compute, and by enabling additional pre-computations. Our solution compares favorably with existing schemes in terms of computational efficiency, communication cost and memory requirements, and is secure in the random oracle model.
