Terence,
Interesting article and technology.
4 things spring to mind...


- you propose to offer open licensing...in what form ?
Is this of the technology (IBE) or only if one uses your toolkit ?.
e.g. can one write and use an open source library directly derived from Boneh and Franklin's paper (which you have patent rights) ?


- will you be publishing the message and key formats ?


- are there any performace numbers for your technology, say compared to RSA ?


- how do you secure traffic to anonymous!


yours etc.,
/Anonymous

    Great questions!

    1. Licensing - We are still deciding precisely what licensing terms will be offered, but we are committed to making the client toolkit freely available, including the ability to modify the toolkit. More details will be forthcoming soon.

    2. Formats - absolutely. We'll be publishing formats and protocols for our products. The toolkit will include enough code to interact with a Voltage SecurePolicy Suite and do things like send secure email, etc.

    3. Performance. We are somewhat slower than RSA on the client (about 2-3x slower, but still in the sub-100 ms. range), but are continually working to optimize implementation of the pairing operation. The server key generation operation is very fast (it's an elliptic curve multiplication), which is nice for scalability. Different curve families also have different performance characteristics. We'll have a tech note on our site later on that will give more details.

    4. Anonymous. Hmmm, we'll have to think about this one! I guess it depends on your SecurePolicy Suite's policy on who it will give a key for anonymous to. There might actually be a cool protocol possible here to dynamically allocate psuedonyms using IBE. Good food for thought!
