Inthis short note, we study all-or-nothing transforms, which wererecently proposed by Rivest as a mode of operation for blockciphers. We study transforms of this type that provide unconditionalsecurity. A simple construction for linear transforms is given,and some existence and non-existence results for general transformsare derived from a combinatorial characterization of these objects.
