Title (EN) NESTED ENCLAVE IDENTITY
(FR) IDENTITÉ D'ENCLAVE IMBRIQUÉE
Abstract:
(EN) A nested enclave identity is presented. A nested identity is indicative of one or more possible enclave instantiations according to one or more identity types. Enclave identities may be nested such that a lower level identity type corresponds to a subset of the possible enclave instantiations that a higher level identity type corresponds to. Techniques disclosed include instantiating an enclave with a nested identity at a software interface to an enclave platform, and performing an operation related to the instantiated enclave using the nested identity.
(FR) L'invention concerne une identité d'enclave imbriquée. Une identité imbriquée indique une ou plusieurs instanciations d'enclave éventuelle selon un ou plusieurs types d'identité. Des identités d'enclave peuvent être imbriquées de telle sorte qu'un type d'identité de niveau inférieur correspond à un sous-ensemble des instanciations d'enclave possibles auquel correspond un type d'identité de niveau supérieur. Les techniques décrites comprennent l'instanciation d'une enclave avec une identité imbriquée au niveau d'une interface logicielle à une plateforme d'enclave, et la réalisation d'une opération relative à l'enclave instanciée à l'aide de l'identité imbriquée.
