Re: TEA for real-life embedded project?

I trust you're not literally using AES decryption on the limited
resource end. You'd want to use encryption only, either via, say, CTR
mode, or by just reversing the roles of encryption and decryption.

What's the difference between the encryption and decryption in AES? I
thought that in symetric ciphers these functions are more or less, well,
symetric :)
