Jan 3, 2017 · The first round of the NIST lightweight cryptography standardization process began with the announcement of 56 Round 1 in April 2019 and ended in August 2019. NISTIR 8268 explains the evaluation of the first-round candidates and names 32 candidate algorithms advancing to the second round of the evaluation process. Round 2.

Block ciphers have been extremely predominant in the area of cryptography and due to the paradigm shift towards devices of resource constrained nature, lightweight block ciphers have totally influenced the field and has been a go-to option ever since. The growth of resource constrained devices have put forth a dire need for the security solu-tions ...
The context of the term “Lightweight” is quite wide, often debatable and of am-biguous nature as well. Lightweight cryptography has been in the scene for a period of more than two decades or so, very evidently by the need for algorithms targeting low-cost implementations both in hardware and software. However, over the years it has received far mor...
It is important to understand the various trends in the design of lightweight block ciphers. There are several involvements both in terms of hardware and software and a variety of metrics as well. The goal of all the primitives is to achieve a trade-o between cost, performance and security where the best that can be achieved is two-fold: a secure a...
There has not been a clear and well-put out taxonomy of lightweight block ci-phers that strictly classifies them into suitable categories due to unclear involvement of ciphers that does not fall into the space of lightweight category of block ciphers. How-ever, our e ort is the first of its kind to present several classifications of lightweight blo...
While studying the field of Lightweight Cryptography, one of the main things we found was that there is no clear and established line drawn as to when we call a ci-pher ‘lightweight’ or ‘ultra-lightweight’ in terms of metrics and performance. As per our knowledge, there is not a single agreed upon universal definition of when a cipher should be cal...
Lightweight block ciphers have been in tremendous demand due to the immense rise of IoT applications and need for secure primitives in applications that have limited resources like that of wireless sensor networks, RFID etc. We look at the state-of-the-art lightweight block ciphers that have been proposed over the years both in academia and by gove...

Mar 5, 2018 · Both the national (NIST) and international (ISO/IEC) organisations outline a number of methods which can be used for lightweight cryptography and which could be useful in IoT and RFID devices [Citation 1]. They define the device spectrum as follows: Conventional cryptography. Servers and Desktops; Tablets and smart phones. Lightweight ...
