Method for realizing data cross-platform sharing by configuring key pair

Abstract

The invention discloses a method for realizing data cross-platform sharing by configuring a key pair in the technical field of data cross-platform sharing. The sharing platform encrypts the second-level key through the first-level key, generates a shared encryption key, encrypts the shared data through the secondary key, and generates shared encrypted files; the shared platform sends a private keyand a main key used by the data sharing request to the key management server; the private key of the shared platform are paired with the secondary key by the key management server; the key managementserver decrypts the second-level key to obtain a first-level key, compares the first-level secret key with the main key; and if not, the key management server decrypts the shared data, compresses thedecrypted shared data and then transmits the compressed shared data to the shared platform, so that different platforms realize cross-platform data sharing of the shared data by configuring key pairs, mutual independence of data sharing among different platforms can be ensured, and relatively high data sharing security is achieved.

Description

technical field [0001] The invention relates to the technical field of cross-platform data sharing, in particular to a method for realizing cross-platform data sharing by configuring key pairs. Background technique [0002] At present, as the network can provide more and more content for users, and the number of users continues to increase, how to improve network security has not only become an in-depth problem in the industry, but also in the era of advanced networks, data as an information carrier , while providing people with convenient and efficient services, the hidden worries of data security issues have always been with us. A reliable way to ensure the security of video data and related information is to encrypt and store sensitive data, and use different key, the cloud server encryption and decryption process has a large computational cost, especially in the case of a large number of terminal devices, the cloud server needs to convert the ciphertext for each terminal...

[0002] At present, as the network can provide more and more content for users, and the number of users continues to increase, how to improve network security has not only become an in-depth problem in the industry, but also in the era of advanced networks, data as an information carrier , while providing people with convenient and efficient services, the hidden worries of data security issues have always been with us. A reliable way to ensure the security of video data and related information is to encrypt and store sensitive data, and use different key, the cloud server encryption and decryption process has a large computational cost, especially in the case of a large number of terminal devices, the cloud server needs to convert the ciphertext for each terminal device, in addition, due to the use of different keys, For the same data, the ciphertexts stored in the terminal devices are different, and data synchronization between terminal devices cannot be performed. Therefore, we propose a method for cross-platform data sharing by configuring key pairs.
