In the field of cloud computing, the meaning of multi-tenancy has been extended as new service models take advantage of virtualization and remote access. For example, a software as a service (SaaS) provider provides Web access services to a plurality of users using an application system running on one database instance. In this scenario, data between tenants is isolated and each tenant's data is guaranteed to be invisible to other tenants.
In both the traditional application scenario and the cloud computing application scenario, software providers need a set of secure trust method to ensure that their software and hardware products are not abused. In the existing multi-tenant secure credit granting method for products, when a tenant uses different services on a cloud platform, such as ECS (electronic communications systems) elastic computing resources, middleware, third-party services, and the like, authorization and authentication solutions possibly adopted by different service providers are inconsistent, requirements on software and hardware of the platform are high, and efficiency is low.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention provides a method, a system and a principle of electronic equipment for multi-tenant secure credit authorization of a product, which are shown in figure 1. Generally, a software service system comprises a product server side and a product client side, and in order to perform secure credit authorization on a software service, the product multi-tenant secure credit authorization system is deployed on the software service system. The product multi-tenant security credit granting system comprises an authorization device and a verification device. The authorization device is deployed at a product server side and is used for providing authorization management of products for a product operation team. The verification device is deployed at a product client and used for verifying the tenant, judging whether the tenant has the use authority of the product and the like. The tenant obtains the use right of the product through purchasing and the like. In one specific implementation, the authorization and verification devices may be software gadgets that are isolated from the source code of the product for ease of maintenance.
The product multi-tenant security trust method provided by the embodiment of the invention comprises an authorization step and a verification step. The authorization step may be performed by an authorization means at the server side. The authenticating step may be performed by an authentication device embedded in the product client.
The authorization step, as shown in fig. 2, includes:
and S1, generating a unique pair of private key and public key for the authorized tenant by adopting an asymmetric encryption algorithm, and storing the association relationship between the public key and the authorized tenant.
For example, when a tenant registers in the platform for the first time, the product multi-tenant security trust device generates a unique pair of private key and public key for each tenant based on a registration request of the tenant.
The public key information is sent to the verifying device, and the verifying device stores the public key of each tenant in association with the unique identifier of the tenant, that is, the public key and the tenant have a one-to-one correspondence relationship, so that the public key corresponding to the tenant can be read according to the verification request in step S4 to perform validity verification and information digest extraction on the signature certificate.
The private key is used to provide step S3 with the message digest to generate a signed certificate.
Preferably, an Elliptic Curve Digital Signature Algorithm (ECDSA) is used to generate a unique pair of private key and public key for each tenant.
Preferably, a salt (salt) is added in the process of generating a unique pair of private key and public key for an authorized tenant by using an asymmetric encryption algorithm, that is, a random key pair after hash of the salt is generated. The salt value is equivalent to an encrypted key, so that the difficulty of cracking is increased, and the safety of one-way hash calculation is enhanced. Common one-way hashing algorithms are MD5, SHA, etc. One feature of the one-way hashing algorithm is that any slight change in the input will result in a complete difference in the output. The salt value can be dynamically changed according to the actual product form and the service form, for example, in the conventional case such as a stand-alone product, the salt value can be a CPU, a main board or BIOS serial number, a MAC address, and the like, and in the cloud mirror image mode, the salt value generated by the key pair can be a tenant code, a UUID. The security of the credit can be further enhanced by adding salt value.
And S2, reading the personal information and the authorization information of the authorized tenant and generating an information abstract of the authorized tenant.
The personal information can be unique identification such as a tenant login name, a mobile phone number, a mailbox and the like.
The authorization information may be authorization information generated by the product operation team according to specific purchased contents after the tenant obtains authorization of the product through a purchase service or the like, for example, the number of supported users, storage space, validity time, an authorization network IP address field, and the like.
The authorization device reads the personal information and the authorization information of the authorized tenant and generates a corresponding information abstract according to the personal information and the authorization information of the tenant.
Preferably, when the authorization information of the authorized tenant changes, a new information summary is generated for the tenant according to the personal information of the authorized tenant and the changed authorization information; and regenerating the signature certificate of the tenant by using the private key corresponding to the tenant and the new information digest. For example, when a tenant needs to renew its product authorization time, expand the number of authorized users, expand the storage space, etc., new authorization information may be generated, so as to update the information digest, generate a new signature certificate, and implement hot update of the trust validity without restarting the product.
And S3, generating a signature certificate of the authorized tenant by using the private key and the information digest corresponding to each tenant.
The signed certificate is provided to the verification device for verification. Many specific implementations are possible. One way is to embed the generated signature certificate into the product client; another way is to send the generated signed certificate to a third-party signed certificate management center for management. The generated signature certificate can also be selectively issued to the tenant for reservation.
Preferably, the generated signature certificate is encrypted and protected by adopting an AES256 encryption algorithm, so that different tenant decryption keys of products are different, and certificate sharing among tenants is prevented.
The verification step, as shown in fig. 3, includes:
and S4, receiving the verification request of the verified tenant, and reading the verification information and the associated public key of the verified tenant.
The verification request can be a login request when the tenant logs in the product system, and can also be a preset timing verification request in the product.
The authentication information of the tenant may be user name, time, and the like when the user logs in.
The associated public key is searched according to the public key sent by the authorization device to the verification device and the association relationship between the public key and the authorized tenant in step S1.
And S5, acquiring the signature certificate of the verified tenant, and verifying the signature certificate of the verified tenant by using the verification information of the verified tenant and the associated public key.
If the signature certificate generated in step S3 is embedded in the product client, the verification device obtains the signature certificate of the tenant from the product client after receiving the tenant verification request. If the signed certificate generated in step S3 is sent to the third-party signed certificate management center for management, when the verification apparatus receives the tenant verification request, the signed certificate of the tenant is obtained from the third-party signed certificate management center.
The process of performing the verification includes two steps: the first step is to decrypt the signature certificate of the verified tenant by using the verification information of the verified tenant and the associated public key, verify whether the public key is matched with the private key in the signature certificate, and if the verification is successful, extract the information digest in the signature certificate. And the second step is to compare and check the verification information of the verified tenant with the recorded information in the extracted information abstract to judge whether the tenant has the corresponding operation permission of the product client.
Preferably, after the tenant logs in the product client, the product client may further determine whether the tenant is the tenant to which the product belongs, and if it is determined that the tenant is the tenant to which the product belongs, the product client reads the public key associated with the tenant.
Preferably, if the AES256 encryption algorithm is used to perform encryption protection on the generated signature certificate after step S3, the signature certificate of the tenant is decrypted by the decryption algorithm before the signature certificate of the tenant is verified.
Preferably, if the extracted information abstract is known to exceed the authorization validity period of the tenant, the tenant is prompted to renew the signature, the certificate abstract information is updated after the tenant completes the renewal operation, the system is triggered to regenerate a new certificate, or a product operation team uses an operation management platform tool to generate a new valid certificate, issues the new valid certificate to the tenant, and then updates the certificate on the platform.
It should be understood that the above steps, although numbered, are not necessarily performed in the order recited, unless explicitly stated herein or order can be inferred directly from the description herein.
The advantages of using the ECDSA asymmetric encryption algorithm are described in more detail below. The signature in the ECDSA algorithm adopts ECC, so that the security and the efficiency of the certificate can be greatly improved, and compared with the RSA digital signature algorithm generally adopted in the prior art, the ECDSA algorithm has absolute advantages in many aspects. Mainly embodied in the following aspects: the anti-attack performance is strong, the anti-attack performance is many times as strong as that of the same secret key length; the calculated amount is small, the processing speed is high, and the total speed of ECC is much higher than that of RSA and DSA; the memory space is small, the key size and system parameters of ECC are much smaller than those of RSA and DSA, which means that the memory space occupied by the ECC is much smaller, and the method has a particularly important meaning for the application of the encryption algorithm on the IC card; the bandwidth requirement is low, when long messages are encrypted and decrypted, the three types of cryptosystems have the same bandwidth requirement, but the ECC bandwidth requirement is much lower when the cryptosystems are applied to short messages, and the low bandwidth requirement enables the ECC to have wide application prospects in the field of wireless networks.
