Hi,
Can anyone suggest a good stream cipher algorithm for hardware implementation.

I'd think AES would be a good choice.

But AES is a block cipher, not a stream cipher. Yes, it can be used in a stream mode, but something else might be better. Questions to the OP: What level of security do you need (ie how well resourced & patient is your adversary)? How much hardware resources can you devote to this function? How fast must it run?
AES is a stream cipher -- every character is just 128 bits. :)

I don't have any specific requirement yet... Inorder to get an hold on stream cipher..i wanted to do an hardware implementation. so i wanted to know the most used sterm cipher algorithm in hardware.. please pass on ur comments on RC4 ,its applications and present use
I'm also interested in hardware stream ciphers, and have been looking at papers related to:

Good luck! alan
Look for 'Self Shrinking Generator', compact and no known attacks yet
