The invention relates to a cryptography attribute-based access control method and system based on a dynamic rule, mainly belonging to the technical field of information. In the cryptography attribute-based access control system based on the dynamic rule, protected objects are stored in a encrypted form, and only the requests satisfying the requirements of access policies in the attribute-based access control can be authorized to decrypt the objects, therefore, it can be ensured that data in an unsafe environment can be accessed with authorization according to a security policy, and meanwhile,the extensibility of the policies and the dynamic acquisition of the attributes are also supported. The cryptography attribute-based access control method and system based on the dynamic rule are divorced from the traditional encryption system framework, and are a new attribute-based access control model, method and system supporting the cryptography decision. The cryptography attribute-based access control method and system based on the dynamic rule can achieve more secure, diversified, dynamic and flexible access authorization, which are suitable for large-scale organizations or informationsystems, and can be applied to the environments such as cloud computing, grid computing, distributed computing, and so on.

Aspects of the disclosure provides a secure key management and data transmission system that includes a transmission system, a data consumer network device, a user network device, and a data transmission network. The transmission management system is configured to receive user-specific data from the user network device via the data transmission network and receive a request for a service corresponding to processing the user-specific data according to a proprietary process provided by the data consumer network device. The transmission management system is also configured to generate service response data based on processing the user-specific data according to the proprietary process in response to the received request, encrypt the service response data to become single-encrypted service response data, transmit the single-encrypted service response data to the data consumer network device, and receive and store double-encrypted service response data from the user network device.

The invention provides a method for sharing user data in a network, a business provider, an identity provider and user equipment (UE), wherein the network comprises the identity provider and a resource server (RS). The method includes that the business provider receives the access of the UE; and the business provider directly or indirectly acquires user shared data authorized by a user from the RS. The business provider can share user data of telecom operators according to the method for sharing the user data in the network, the business provider, the identity provider and the UE.

The invention discloses a cross-chain data sharing method, system and device and a readable storage medium. The method comprises the steps that a main block chain node in a cross-chain platform receives first shared transaction information sent by a source block chain; verifying the first shared transaction information in the trusted execution environment; after all block chain nodes in a preset range in the cross-chain platform pass verification, packaging the second identifier of the source block chain, the first identifier and the target shared data into second shared transaction information; and the second shared transaction information is sent to the target block chain, so that the data can be shared between the two block chains, and further, due to the deployment of the trusted execution environment, the data sharing between the block chains is safer, and the data is prevented from being leaked.

The invention provides a file sharing method and a system. According to the file sharing method, a file sharing request mechanism and a response mechanism are built between a server and a terminal so as to guarantee response and control of file sharing, quick, accurate and safe transmission and sharing of files between specific terminals are guaranteed, and the file sharing is no longer limited by sharing approaches. The invention further provides a file sharing system.

The invention provides a multi-service provider data sharing system with privacy protection based on a block chain. By introducing the block chain, the problem that different service providers need to depend on a trusted third party to share data is solved, a decentralized, reliable and safe trusted system is provided for the different service providers, and the different service providers can share own data onto the block chain trustingly. Meanwhile, a proxy re-encryption technology and bilinear mapping cryptography meta-language are deeply fused, a matchable data encryption algorithm supporting multiple users and multiple service providers and an on-chain protocol matched with data are constructed, and content matching in a ciphertext domain is achieved. The proxy re-encryption algorithm is improved, and the improved algorithm solves the problem of data security caused by the proxy re-encryption method.

The invention discloses a conference information control system based on a wireless network. First valid data is received and sent by a service terminal and encrypted and decrypted by main encryption and decryption equipment, and the first encrypted and decrypted valid data is communicated with a client terminal through the wireless network; and second valid data is received and sent by the client terminal and encrypted and decrypted by secondary encryption and decryption equipment, and the second encrypted and decrypted valid data is communicated with the service terminal through the wireless network. A network structure of the conference information control system is divided into an external network and an internal network, wherein the external network and the internal network are isolated by the main encryption and decryption equipment and the secondary encryption and decryption equipment, the internal network is a local wired network, and the external network is a wireless encryption network.
