Identity-based public key cryptography

[John Williams]

The powers that be continue to agonise over the use of cryptographic
services for the NHS.  Setting up the necessary PKI seems to be particularly
challenging.

Then all of a sudden we are being told about ID-PKC where no complicated PKI
is needed.  Public keys can be computed and we get our private keys from a
CA.  The CA can be split into pieces so that only someone with all of the
pieces gets to have the working private key.  How secure is this system and
is it in use anywhere?  It seems too good to be true and I feel uneasy about
where I am being told to go to view it from:

Does this have any place?
