Abstract

Technologies for remote attestation include a group member device to generate a signature of a message using a cryptographic key assigned to the group member device by a group manager and determine an authentication path that indicates a plurality of cryptographic hashes necessary to compute a group public key of a group associated with a plurality of group member devices. The cryptographic key is assigned to the group member device based on a permutation of a set of cryptographic keys generated by the plurality of group member devices. The group member device transmits the signature and the authentication path to a verifier device for verification of the signature.
