WebMoreover, a bitslice version of the cipher is used with the parity bit code applied to be robust against all the single-word fault injections. The challenge is to adapt the cipher functions in a way in which the parity bit is always considered, but without considering a heavy implementation. ... In IEEE Computer Society, Proceedings of the 23rd ... The complexities of creating a new computer architecture were greatly reduced when the details of the ALU were already specified (and debugged). The main advantage was that bit slicing made it economically possible in smaller processors to use bipolar transistors , which switch much faster than NMOS or CMOS … See more Bit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n-bit central processing unit (CPU). … See more Software use on non-bit-slice hardware In more recent times, the term bit slicing was reused by Matthew Kwan to refer to the technique of using a general-purpose CPU to implement multiple parallel simple virtual machines using general logic instructions to … See more Bit-slice processors (BSPs) usually include 1-, 2-, 4-, 8- or 16-bit arithmetic logic unit (ALU) and control lines (including carry or overflow signals that are internal to the processor in non … See more Bit slicing, although not called that at the time, was also used in computers before large-scale integrated circuits (LSI, the predecessor to today's See more • Bit-serial architecture See more • "Untwisted: Bit-sliced TEA time".

WebSep 9, 2012 · It is also expected that bitslice implementation offers resistance to side channel attacks such as cache timing attacks and cross-VM attacks in a multi-tenant cloud environment. Lightweight cryptography is not limited to constrained devices, and this work opens the way to its application in cloud computing. References WebFeb 21, 2024 · Matthew Kwan made a brief recap in his paper "Reducing the Gate Count of Bitslice DES" of Biham original paper. He wrote: Basically, for each S-box, the technique is to take two of the input bits, expand them to all 16 possible functions of two variables, and use the remaining four S-box inputs to select from those 16 functions.
Am2900 is a family of integrated circuits (ICs) created in 1975 by Advanced Micro Devices (AMD). They were constructed with bipolar devices, in a bit-slice topology, and were designed to be used as modular components each representing a different aspect of a computer control unit (CCU). By using the bit slicing technique, the Am2900 family was able to implement a CCU with data, addre… WebNov 4, 2010 · Bitslice is a non-conventional but efficient way to implement DES in software. It involves breaking down of DES into logical bit operations so that N parallel encryptions are possible on a single ...
