Multiple Hashing Using SHA-256 and MD5
2021Message Digest 5 (MD5) is a hashing function with numerous vulnerabilities such as pre-image vulnerability and collision vulnerability which restrict the usage of MD5. Therefore, by using other hashing functions such as SHA prior to hashing with MD5, we can use MD5 for various applications such as data integrity without compromising the security of the

VLSI implementation of high-speed SHA-256
2009 IEEE 8th International Conference on ASIC, 2009To accelerate the speed of iterative computation for the existing SHA-256 algorithm, using 7-3-2 array compressor is proposed to reduce the critical path delay in this paper. The frequency of the proposed scheme is 1.7 times higher than other VLSI implementations under the same process.

Authentication Process in Smart Card Using Sha-256
Journal of Computational and Theoretical Nanoscience, 2020Smart cards are related to the issues of security. The applications of smart card are manipulated in hardware, software and telecommunications which appears to be a big issue. In this paper we introduce a new design which is a secured 2 level processing in authentication which uses the number of the pin as 1st authenticated level by the use of SHA-256.

An FPGA Based SHA-256 Processor
2002The design, implementation and system level performance of an efficient yet compact field programmable gate array (FPGA) based Secure Hash Algorithm 256 (SHA-256) processor is presented. On a Xilinx Virtex XCV300E-8 FPGA, the SHA-256 processor utilizes 1261 slices and has a throughput of 87 MB/s at 88 MHz.

A High-Throughput Hardware Implementation of SHA-256 Algorithm
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020The SHA-256 algorithm is widely used in the field of security. In this paper, we propose a rescheduling method for the SHA-256 round computation. Based on the proposed rescheduling, we propose a design for SHA-256, in which the critical path is reduced. Our design is implemented on the Xilinx Virtex-4 FPGA.

Validating of Digital Forensic Images Using SHA-256
2019 International Conference on Cyber Security and Internet of Things (ICSIoT), 2019Volumes of digital images are produced per time, whiles these digital images may be for friendly and or social activities they can be manipulated for illegal purposes. Sensitive digital images have been a core part of security correspondences between sensitive institutions. Such sensitive digital images security has been a prime concern.

A Configurable Implementation of the SHA-256 Hash Function
2019This paper proposes a hardware solution for the SHA-256 hash function offering a number of configurable architecture-level features. This flexibility allows for exploring various trade-offs between performance, area occupation, and power consumption. As confirmed by the experimental results, the approach succeeds in exposing the effects of different ...
