Do you know more about how it works? I'm curious how something which sounds from your description to be really light-weight can be equivalent to RSA.
Thanks. Nick Owen wrote:
Just one thought: we have used a commercial encryption package from Ntru for asymmetric encryption on wireless devices (we're using it for a two-factor authentication system). It is incredibly fast and incredibly small. The keys are 5k, our entire J2ME package is about 32k. The key strengths are equivalent to 1024 bit RSA. On a J2ME phone, key gen takes about 14 seconds, compared to 14 hours or so for ECC and 2+ days for RSA (had to kill it). We were using the Nextel 1st generation phones as well, the newer ones are faster. On a Blackberry or Palm, you hardly notice the key gen or encryption, in fact, the network lag is the key drag. I know that Ntru did some implementation for a Wi-Fi project. I think that it would be a great solution for asymmetric encryption for Wi-fi, if you had a particular need that warranted it. My assumption is that it was not considered for WEP because it's a commercial product.
