Cryptography in Microcontroller
One of my junior at President University, Edi Permadi finally released his works on the net about en/decryption and hashing method for PIC16F84. I personally like cryptography as well as its implementation in hardware (microcontroller or IC design). His works which already published are :
Implementing Simplified DES using PIC16F84
Direct file download :
Implementing MD5 using PIC16F84
Implementing Simplified DES using EEPROM
Simplified DES Simulator
Direct download :
To open files above you will need WinRAR or 7-ZIP (recommended)
My comment :
It is a very interesting implementation, however NIST has chosen Rijndael to replace DES. I hope in the future he will be able to implement Rijndael in microcontroller or FPGA.
MD5 is no longer secure, it has collision. SHA1 is much better.
