Abstract. The PCBC block cipher mode of operation has many variants, of which one, due to Meyer and Matyas, dates back over 20 years. Whilst a particularly simple variant of PCBC h...

We investigate the all-or-nothing encryption paradigm which was introduced by Rivest as a new mode of operation for block ciphers. The paradigm involves composing an all-or-nothing...

Ding et al [DNRS97] propose a stream generator based on several layers. We present several attacks. First, we observe that the non-surjectivity of a linear combination step allows ...
