Encryption on a PIC18


Robust encryption is often difficult to achieve on a microcontroller given the limited processing power and memory. The Microchip PIC18 series are capable of some forms of limited data encryption. Four encryption algorithms including AES, XTEA, SKIPJACK® and a simple encryption algorithm using a pseudo-random binary sequence generator are described in this application note.

    There is alredy an encryption library for AVRs, made by “Das Labor”. :)

    I think we covered that one last week :)

    This remembers me of a thesis I once did, where I implemented the AES encryption/decryption on an Atmega8.
