Urgent:fastest and most secure crptographic algorithm

[jskemb]

Hi guys,

I am workin on a small project where i need to use the fastest and the most secure cryptography algorithm for a small microcontroller.Its for secure data(text) communication between a client and server.

Have gone through a lot of the common ones like RSA,AES,blowfish etc. but have not managed to finalise which im gonna use.

If any ones worked on anythin like this before do get back to me as to which one is better and why.Also would like to know which one is the latest to be used.Do attach some valuable links too.
Thanks and regards,

jskemb

more secure

use Symmetric Cryptography(secret key cryptography...fast) and Asymmetric Cryptography(sharing key)

enjoy

thanks for the prompt reply but which specific algo is good...or a hybrid is a better option?

dear you can use AES is mor simple and non intensive for your h/w
then use blowfish
