Abstract. This paper presents xmx, a new symmetric block cipher optimized for public-key libraries and microcontrollers with arithmetic coprocessors. xmx has no S-boxes and uses on...
In [1] a construction of a block cipher from a single pseudorandom permutation is proposed. In a complexity theoretical setting they prove that this scheme is secure against a pol...
- Maintaining digital security and privacy are critical issues in the modern workplace. Sensitive and proprietary data is frequently transmitted electronically, and with the large ...
: Large-scale deployment of virtual private networks with hundreds or thousands of clients means a constant battle with complexity that can only be won by setting up powerful authe...
We introduce a world vision in which data is endowed with memory. In this data-centric systems paradigm, data items can be enabled to retain all or some of their previous values. ...
