  • Abstract
    A method is proposed for a key safeguarding scheme (threshold scheme) in which the shadows are congruence classes of a number associated with the original key. A variation of this scheme provides efficient error detection and even exposes deliberate tampering. Certain underlying similarities of this scheme with Shamir´s interpolation method make it possible to incorporate these protective features in that method as well.
