Abstract
A computer-implemented method for authenticating messages relative to a hash-based data authentication structure includes producing a first signed data structure that includes one or more node hash values from the hash-based data authentication structure. The node hash values are selected according to a selected strategy and configured to authenticate messages relative to the hash-based data structure. The method further includes producing a second signed data structure that is a modified version of the first signed data structure. The method further includes enabling a signed data structure provider to provide to a verifier the first signed data structure and the second signed data structure. The method further includes enabling an authentication path provider to provide to the verifier an authentication path formed relative to the first signed data structure or the second signed data structure. The verifier determines whether to use the first signed data structure and performs a verification procedure.
