Ip Core Design of Hight Lightweight Cipher and Its
In the present era of e-world where security has got a larger weightage, cryptography has its role to play. Nowadays, the devices available in the market are of resource constrained type. Hence we need lightweight ciphers for the efficient encryption of data thereby increasing the performance. In this project a detailed study of HIGHT cryptographic algorithm is done which outperforms standard a...
متن کاملHIGHT: A New Block Cipher Suitable for Low-Resource Device
In this paper, we propose a new block cipher HIGHT with 64-bit block length and 128-bit key length. It provides low-resource hardware implementation, which is proper to ubiquitous computing device such as a sensor in USN or a RFID tag. HIGHT does not only consist of simple operations to be ultra-light but also has enough security as a good encryption algorithm. Our hardware implementation of HI...
متن کاملCryptanalysis of Reduced Versions of the HIGHT Block Cipher from CHES 2006
HIGHT is a 32-round block cipher with a 64-bit block size and a 128-bit user key, which was proposed at CHES ’06 for low-resource applications like RFID. In this paper, we present an impossible differential attack on 25-round HIGHT, a related-key rectangle attack on 26round HIGHT, and finally a related-key impossible differential attack on 28-round HIGHT. Our result suggests that the safety mar...

متن کاملAnalysis and design of block cipher constructions
This thesis is dedicated to symmetric cryptographic algorithms. The major focus of the work is on block ciphers themselves as well as on hash functions and message authentication codes based on block ciphers. Three main approaches to the cryptanalysis of symmetric cryptographic algorithms are pursued. First, several block cipher constructions are analyzed mathematically using statistical crypta...
