The invention provides a third-party-based verified information non-leakage
data integrity and
data source verification method which comprises a third-party-based verified information non-leakage dataintegrity and source
verification method in a
simple mode, a third-party-based verified information non-leakage
data integrity and source
verification method in a
key exchange mode and a third-party-based verified information non-leakage
data integrity and source verification method in a
secure communication mode, wherein the third-party-based verified information non-leakage data integrity and source verification method in the
simple mode is used for a case that verified and transmitted data is a cleartext, a sender does not encrypt the data and a
receiver also does not need to decrypt the received data; according to the third-party-based verified information non-leakage data integrity and source verification method in the
key exchange mode, on the basis of the
simple mode, key securitytransmission is further provided for the sender and the
receiver so as to support more
secure communication between the sender and the
receiver; and according to the third-party-based verified information non-leakage data integrity and source verification method in the
secure communication mode, on the basis of the simple mode, the verified and transmitted data is a
ciphertext. Acquired information can be used for identity verification of both the sender and the receiver, and two users who do not know public keys of opposite parties are allowed to verify an integrity and a source of data sentbetween the users, and the third-party-based verified information non-leakage data integrity and source verification method can be used for defending internet frauds and establishing an authoritativeinformation release and verification platform.
