Instant communication message uplink method and device

Номер: CN115987931A
Автор: WANG YONGNAN, XIE LIHUA
Принадлежит:

The invention provides an instant messaging message uplink method and device, and the method comprises the steps: transmitting a target message to a chat server for instant messaging from the local, so as to enable the chat server to transmit the target message to a destination node; and based on the unique corresponding symmetric key and private key obtained from the block chain server in advance, encrypting and signing the target message sent to the target node locally to form a data packet, and sending the data packet to the block chain server for uplink storage. According to the method and the device, the chat and the block chain function can be decoupled, so that the chat efficiency of the user is not influenced by the block chain, the data of the block chain service is not influenced even if the chat server is not credible, the security of data transmission can be effectively improved by using a mode of combining symmetric encryption and asymmetric encryption, and the user experience ...

Uplink method and device for instant messaging historical messages

Номер: CN116032875A
Автор: WANG YONGNAN, LI SHIDA
Принадлежит:

The invention provides an instant messaging historical message uplink method and device, and the method comprises the steps: extracting a target instant messaging historical message corresponding to a historical message uplink request sent by an instant chat user from historical uplink failure chat data corresponding to an instant messaging chat system; and judging whether the target instant messaging historical message is authorized to be linked or not, and if yes, uploading the target instant messaging historical message to a block chain for storage. According to the method and the device, the instant messaging historical information which fails to be chained can be chained again, so that the instant messaging historical information which needs to be safely stored can be chained, the reliability and comprehensiveness of instant messaging information chaining can be effectively improved, the flexibility of instant messaging historical information chaining can be effectively improved, and ...

Data encryption method and device for block chain data

Номер: CN116192486A
Автор: WANG YONGNAN, XU SHAOXIANG
Принадлежит:

The invention provides a data encryption method and device for block chain data, and the method comprises the steps: a first client generates an asymmetric key, and transmits a public key to a server; the server side generates a symmetric key, determines an encryption and decryption algorithm agreed by the first client side and the server side, encrypts the symmetric key based on the agreed encryption and decryption algorithm to obtain a first ciphertext, asymmetrically encrypts the first ciphertext based on a received public key to obtain a second ciphertext, and sends the second ciphertext to the first client side; the first client decrypts the second ciphertext based on the private key to obtain plaintext information corresponding to the second ciphertext, and decrypts the obtained plaintext information based on an agreed encryption and decryption algorithm to obtain symmetric key original data; and the first client encrypts the communication data based on the symmetric key original ...

Instant messaging chat data uplink process exception processing method and device

Номер: CN116319637A
Автор: WANG YONGNAN, CHEN SHIPING
Принадлежит:

The invention provides an instant messaging chat data uplink process exception processing method and device, and the method comprises the steps: obtaining a block chain opening interface state in an instant messaging chat process of a user, and judging whether the block chain opening interface state is normal or not; under the condition that the interface state is abnormal, interface state abnormal data is acquired, a block chain process is initialized and closed, and an instant messaging chat process is entered; under the condition that the interface state is normal, acquiring blockchain opening information data of the user, and judging whether the blockchain opening information state is normal or not; under the condition that the opening information state is abnormal, obtaining opening information state abnormal data, initializing a block chain closing process, and entering an instant messaging chat process; and under the condition that the opening information state is normal, judging ...
