Hardware based MD5 implementation using VHDL for secured embedded and VLSI based designs
Irfan A. Landge, B. K. Mishra · 2016
Many modern electronic systems like PDAs, cell phones, network routers, smart cards, and networked sensors are in need to access, store, manipulate, or communicate sensitive information, making security a serious concern in their design. Embedded and VLSI systems, which account for a wide range of products from the electronics, semiconductor, telecommunications, and networking industries, requires some of the most demanding security concerns. Embedded and VLSI based systems are mainly resource constrained and frequently need to operate in physically insecure environments. Whenever personal or confidential data is processed or stored security objectives like authenticity and integrity have to be fulfilled. This security objective must be ensured by the application or underlying hardware. Hardware implementation aspects of the MD5 hash algorithm using VHDL are discussed in this paper.
