ASYMMETRIC ENCRYPTION SCHEME FOR SECURE DATA TRANSMISSION

摘要

A data access computing device is provided. The data access computing device receives a token request from a user computing device, generates a secret value unique to the token request, encrypts the secret value using a private key associated with the data access computing device, encrypts the secret value using a public key associated with the relying party to generate a sharing token, transmits the sharing token to the user computing device, receives a payload encrypted using a private key associated with the relying party from a relying party computing device, where the payload includes the secret value and a nonce value, decrypts the payload using the to recover the nonce value and the secret value, retrieves the at least one user data element from the database based on the secret value, and transmits the at least one user data element to the relying party computing device.
