"eCash software uses digital signature technology based on
public key cryptography, to provide authentication,
non-repudiation, data integrity, and confidentiality. For the maximum
security available, eCash uses 768-bit RSA keys
with 3-DES. eCash is a very efficient protocol, which
enables key lengths to increase over time without unduly
impacting performance. eCash uses Secure Hash Algorithm
(SHA-1) for its cryptographic hash function. eCash owns
and uses a patented blind signature encoding algorithm that
allows banks to issue eCash, which can be sent from
consumer to merchant in complete privacy. As financial
institutions develop interoperable certificate authorities for issuing
digital certificates, eCash will apply standard bank digital certificates
to eCash payment protocols."
Website is still in the construction phase and only limited info there.
The 768-bit RSA keys seem a little small and I am not all that sure that
3-DES is the best choice of symetric algorithms for this application.
It is good to see that someone is putting the patents to use rahter than
let them collect dust on a shelf until they expire (anyone know when that
is?)
