Embodiment Construction

[0038] figure 1 It is a schematic diagram of a typical mobile smart device data security service network environment that supports attribute-based encryption, that is, a mobile smart device data security service implementation system that supports attribute-based encryption. The system mainly includes four parts:

[0039] Mobile smart devices (such as mobile phones, PADs, etc.): are the demand side of services.

[0040] Authentication service provider: In the system initialization phase, it is mainly responsible for generating the master key and public key of the system; in the data upload phase, it is mainly responsible for uploading the session key and generating the LSSS matrix (Linear Security Shared Scheme Matrix); in the data download phase, it is mainly responsible for Responsible for downloading session keys and generating attribute-based decryption keys; in addition, providing key query services for encryption agents through the Restful interface, and managing informa...

Abstract

The invention discloses a mobile intelligent device security service implementation method and system supporting attribute based encryption. The constructed attribute based encryption service system comprises an authentication service provider and an attribute based encryption proxy. When the system is initialized, the authentication service provider generates a public key and a master key of the attribute based encryption service system and transmits the public key and the master key to the encryption proxy. On one hand, attribute based encryption service is provided for a mobile intelligent device to upload data to a third party. On the other hand, attribute based decryption service is provided for the mobile intelligent device to download the data. The mobile intelligent device realizes attribute based decryption of the third party for uploading and downloading the data through the authentication service provider and the encryption proxy, and fine-grained access control for the data can be realized by the aid of a user identity. Attribute based encryption and fine-grained management based on ABE (attribute based encryption) for the data can be realized, and the system has the advantages of high data security, low expenditure and high encryption and decryption speed.

Description

technical field [0001] The invention relates to the fields of information security and communication, in particular to a method and system for implementing security services of mobile smart devices supporting attribute-based encryption. Background technique [0002] Mobile smart devices have the ability to access the Internet, and mainly include mobile phones, tablets, portable navigation products, and wearable devices. Due to problems such as limited computing, storage and battery life of mobile smart devices, it is difficult to complete all operations on the local terminal, and a third party is required to assist. Therefore, a large number of personal data of mobile smart devices will be stored in a third party, and the third party that provides data storage may misuse the user's data for its own benefit, and an effective encryption mechanism is needed to ensure the security of these outsourced data . [0003] At present, a better method is to use Attribute-Based Encrypt...
