Therefore, how to enable a user to enjoy the convenient and fast use of the cloud server without worrying about the security and confidentiality of data stored in the cloud end is a problem which needs to be solved urgently. Data encryption is an effective means for ensuring data privacy, and encryption methods with various functions and different safety strengths are researched and put into use at present, such as a symmetric encryption algorithm and an asymmetric encryption algorithm; in addition, while the security and the efficient search of the cloud-side data are ensured, the legal access right given to the relevant data by the user is very important in the data sharing process.

In daily work, each nuclear power equipment part opened by a user on a collaborative design platform must have a definite identification code.
And starting an initialization algorithm INIT, and generating and outputting a public key PK and a system master key SK to a specified engineer by the enterprise private cloud storage server according to the specified nuclear power equipment identification attribute PA and the safety parameter SA.
(2) When large-scale simulation analysis of the identified and coded nuclear power equipment is carried out, an engineer further uses an HPC comprehensive management sub-node which is specially used for carrying out high-performance computing in an enterprise collaborative design platform, software and hardware computing resource lists of different disciplines and different categories, which can be provided by a public cloud of an external super-computing center, can be clearly browsed in the sub-node, and the engineer can select corresponding computing resource items according to actual simulation requirements (see the attached figure 2).
(3) After selecting the public cloud computing resource items, the simulation computing engineer can directly log in a public cloud computing platform of an external super computing center, and freely call a high-performance computing cluster to perform various large-scale simulation computing work such as structural analysis, fluid analysis, optimization analysis and the like of the identified nuclear power equipment by using the platform, wherein each nuclear power equipment analysis task generates a new computing task identification code when submitting computing, and generates corresponding computing result data after computing.
(4) The simulation computation engineer segments the obtained computation result data D into core key data D by using a data segmentation algorithm according to the obtained computation result data D1And non-core critical data D2. Core Key data D1After being transmitted to the enterprise private cloud storage server, the key ciphertext data SD is output based on the attribute control algorithm by combining the public key PK and the calculation operation identification JID to be encrypted1(ii) a Non-core critical data D2After the secret key pair D is transmitted to the super-computation public cloud storage server, a symmetric encryption key SEK is randomly selected in a key space and is subjected to D pair based on a searchable encryption algorithm2Encrypting and outputting non-key ciphertext data SD related to calculation operation identification JID2(see FIG. 3).
(5) When the nuclear power equipment collaborative design needs to be developed, a professional simulation computing engineer confirms the identity through an enterprise LDAP unified authentication mechanism, and logs in to enter a collaborative design management service platform based on a nuclear power identification analysis system to develop daily work. In daily work, engineers can open a specific nuclear power equipment part data index information base consistent with the designated identification coding information in the self-arranged work task by means of an identification analysis system on the collaborative design platform.
And starting a private key generation algorithm of the collaborative design engineer, and generating a private key UK of the collaborative design engineer according to the authority attribute UA of the engineer, the public key PK of the private cloud storage server and the system master key SK.
(6) Sixthly, when the collaborative design engineer needs to review/collate/review certain specific simulation calculation result data of a specific nuclear power equipment part, inquiring all calculation tasks with definite identification codes belonging to the nuclear power equipment part by means of the identification analysis system again, and sending a search request for searching relevant simulation calculation data matched with the nuclear power equipment part and the calculation task identification codes to the nuclear power collaborative design platform.
And the collaborative design engineer uses the private key UK and the to-be-searched computing task identifier JID' to send to the private cloud server, and uses a threshold generation algorithm to output a threshold value THRES.
(7) According to the search request, when the corresponding identification verification of the nuclear power equipment and the authority verification of the collaborative design engineer pass consistently, a file server in the nuclear power collaborative design platform searches for part of encrypted data corresponding to the simulation computing task conforming to the identification coding information in the enterprise private cloud storage and part of encrypted data corresponding to the simulation computing task conforming to the identification coding information in the super-computation public cloud storage respectively (see the attached figure 4).

The present invention relates to the field of the terminology as follows:
lightweight directory access protocol LDAP: this is an open, neutral, industry standard application protocol that provides access control and maintains directory information for distributed information via the IP protocol. One common use of LDAP is single sign-on, where a user may use the same password in multiple services, typically for logging-on to a company's internal website. The various software applications may no longer use a unique user management approach, but rather perform user authentication through such a unified authentication mechanism.
The core of the identification analysis system comprises three parts of identification codes, an identification analysis system, identification data services and the like: identification coding involves techniques for data structure definition, distribution and management of the coding format of an object; the system for analyzing the identification can inquire the network position or the related information of the target object according to the identification code, and can carry out uniqueness positioning and information inquiry on the target object; the identification data service can be used for carrying out industrial identification data management and networked data sharing by means of identification coding resources and an identification analysis system.
The symmetric encryption algorithm appears earlier and the system is more perfect, and is the only encryption form before the public key encryption algorithm appears. Symmetric encryption algorithms are still widely studied and used today, based on their own advantages. In the symmetric cryptosystem, a user encrypts and decrypts data using the same key. The two communication parties select the same key through negotiation, trust each other and ensure that the key is not leaked. The security of the symmetric cryptosystem is mainly determined by the privacy of the secret key and is not related to the encryption algorithm.
The public key encryption algorithm, public key cryptography proposes to separately process the encryption and decryption keys in the cryptosystem, the encryption key is a public key and is publicly transmitted on the network, and the decryption key is a private key and is kept by the user. The basic principle of public key cryptography is based on a one-way function, namely, a corresponding public key can be obtained by calculation by using a private key, but the public key can hardly be derived from the private key, so that the public key cryptography is safer than symmetric cryptography.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
