The cross platform digital signature system of the signature messenger can ensure the confidentiality, information integrity, non repudiation, and post traceability of the transaction process in critical business applications. The digital signature, digital envelope, and signed digital envelope functions provided by the cross platform digital signature system through the signature messenger can meet four security requirements for information:

Identity authentication: By verifying the recipient's encrypted package, the identity of the receiver can be guaranteed; Verify that the signature package can identify the sender's identity;

Confidentiality: All plaintext information is encrypted and transmitted using symmetric encryption algorithms through the digital envelope mode;

Integrity: Ensure that data is not altered during transmission.

Non repudiation: Using digital signature mode, the information sent is processed using the user's private key for signature algorithm calculation, and only the user can complete this operation.
