VIRTUAL ACCOUNT AND TOKEN-BASED DIGITAL CASH PROTOCOLS |
摘要 |
The virtual account and token-based digital cash token protocols use a combination of blind digital signatures and pseudonym authentication with at least two pairs of public and private keys. A user has one master pair of private and public keys and many pseudonym pairs of private and public keys. The new protocols combine blind digital signature and pseudonym-based authentication. Blind digital signatures based on the master pair of keys are used to withdraw digital cash from the user's bank account under the user's real identity. A pseudonym pair of keys is used for depositing digital cash with a digital cash issuer. Pseudonym key pairs are used for spending the digital cash. Digital cash includes digital cash tokens in virtual accounts, which can be managed from a user's fixed or mobile computing platform. |
