i made 2 libraries for encryption with arduino environment. One is AES-256 the other is RSA-512. Both are working fine with my Duemilanove
board.
AES-256 Block crypt approx. 1ms/block
RSA-512 appr. 500ms enc and 20s decrypting / block.
If anyone is interested i can post the Libraries.
Ive got implementations of IDEA and the MD5 checksum that could be modified for an 8bit processor pretty easily. Cryptology has always interested me ever since I took a class on it at school.
Hey i am working on an ecryption algorithm also. I have the code too but I was looking for arduino type processors which would allow me to speed up the process since right now is pretty slow. Do you know of any?
I would appreciate of any help.
