Embodiment 1

[0051] A high-security proprietary document transfer method, see figure 1 , including the following steps:

[0052] S1: The authority randomly generates an SM4 symmetric key, and uses the SM4 symmetric key to encrypt the special document to be delivered to obtain the encrypted document;

[0053] S2: The agency end encrypts the SM4 symmetric key to obtain the encryption key, including:

[0054] The agency end receives the entered unique ID of the party; the unique ID of the party is used to uniquely identify the party.

[0055] The agency uses the unique identifier of the party and the IBE asymmetric public key to perform IBE encryption on the SM4 symmetric key to obtain the encryption key.

[0056] S3: The agency side delivers the encrypted document and encryption key to the party side through the delivery platform, including:

[0057] The agency generates delivery information;

[0058] The agency sends the delivery information, encrypted documents and encryption keys to t...

Embodiment 2

[0074] A high security dedicated document delivery system, see figure 2 ,include:

[0075] Agency end: used to randomly generate SM4 symmetric key, and use the SM4 symmetric key to encrypt the special document to be delivered to obtain the encrypted document; the agency end is also used to encrypt the SM4 symmetric key to obtain the encryption key , deliver the encrypted document and encryption key to the parties through the delivery platform;

[0076] delivery platform;

[0077] Party side: used to decrypt the received encryption key to obtain the plaintext of the SM4 symmetric key, and use the plaintext of the SM4 symmetric key to decrypt the received encrypted document to obtain the plaintext of the special document.

[0078] Preferably, the organ end is specifically used for:

[0079] Receive the entered unique identifier of the party, and use the unique identifier of the party and the IBE asymmetric public key to perform IBE encryption on the SM4 symmetric key to obta...

Abstract

The invention provides a high-security special document transmission method and system, and the method comprises the following steps that an organ end randomly generates an SM4 symmetric key, and carries out the encryption of a to-be-delivered special document through the SM4 symmetric key, so as to obtain an encrypted document; the organ end encrypts the SM4 symmetric key to obtain an encrypted key; the organ end sends the encrypted document and the encrypted key to the party end through a delivery platform; the party end decrypts the received encryption key to obtain an SM4 symmetric key plaintext; and the party side decrypts the received encrypted document by using the SM4 symmetric key plaintext to obtain a special document plaintext. According to the method, the risk of privacy leakage of the parties is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic special document delivery, and in particular relates to a high-security special document delivery method and system. Background technique [0002] The private document service process needs to protect the privacy of the parties involved. The existing methods of service of special documents mainly include the following: 1. Direct service is adopted; 2. If the recipient refuses to accept it, service can be retained; 3. If direct service is difficult, relevant parties can be entrusted 4. Delivery by mail; 5. If the whereabouts of the person to be served is unknown or cannot be delivered by other means, it can be delivered by announcement. [0003] The above methods of delivery usually put the special documents in the file bag and add a seal to avoid the leakage of the parties’ privacy. However, this method of delivery still has the risk of the parties’ privacy leakage. Contents of the invention...
