摘要： A method of data transfer from a tenant to a service provider comprises encrypting the data with a public key of a key pair generated by a secure device within the service provider system. The data thus cannot be accessed by the service provider during transmission. The data is generated with a corresponding access control list, which specifies that a valid certificate must be presented in order to grant a particular use of the data once stored. The tenant can thus retain control of the use of the data even though it has been transferred out of the tenant system. A method of controlling use of data securely stored in the service provider system comprises issuing a use certificate having an expiry time to the party requesting use of the data. The use certificate must be validated before use of the stored data is granted. This enables the tenant to grant use of the stored data for a limited time period.
摘要翻译：从租户到服务提供商的数据传输方法包括利用由服务提供商系统内的安全设备生成的密钥对的公钥来加密数据。因此数据在传输过程中无法被服务提供商访问。数据是通过相应的访问控制列表生成的，该列表指定必须呈现有效的证书，以便一旦存储数据即可授予特定用途的数据。因此，租户可以保留对数据使用的控制权，即使已将其转出租户系统。控制使用安全地存储在服务提供者系统中的数据的方法包括向请求使用数据的一方发出具有到期时间的使用证明。在使用存储的数据之前，必须验证使用证书。这使租户能够在有限的时间内使用存储的数据。
