The following module was proposed for inclusion in the Module List:
modid: Crypt::SDTree
DSLIP: ad+Ol
description: A Subset Difference Encryption Scheme
userid: BERNHARD (Bernhard Amann)
chapterid: 14 (Security_and_Encryption)
communities:
https://github.com/amannb/perl-crypt-sdtree
similar:
rationale:
The module implements a broadcast encryption scheme, that can be
used to encrypt data in a way that a large number of users can
decrypt it. Furthermore, it is later possible to efficiently revoke
access to groups of users; the individual users do not have to hold
any state.
A subset difference revocation algorithm is for example used in
AACS (the Blu-Ray DRM system) (the implementation here should
actually be quite similar to what they do).
The module implements a perl interface for the subset difference
revocation/broadcast encryption scheme. The scheme that is
implemented should be mostly equivalent to the one proposed by Naor
et al. in http://www.wisdom.weizmann.ac.il/~naor/PAPERS/2nl.pdf.
