One of the major sources of information in recent times is the internet, which facilitates the exchange of information between thousands of people at any instant. The transmission of sensitive data such as passwords must be accompanied by some form of robust protection to ensure prevention of unauthorized access. The requirement of strong encryption algorithms is of utmost importance. In this paper we present the Verilog description and hardware implementation on Altera DE2115 board of password encryption using Blake 256 cryptographic hash function coupled and parallel CRC for high performance, transmission error control. © 2015 IEEE.
