Abstract: A method for extending a memory isolation domain includes allocating memories of multiple isolation domains, where the multiple isolation domains are in a correspondence with N protection keys and M extended page tables. When a first application is allowed to access a memory of a first isolation domain, the method further includes determining, based on the correspondence, a first protection key and a first extended page table that correspond to the first isolation domain, where the multiple isolation domains include the first isolation domain, the N protection keys include the first protection key, and the M extended page tables include the first extended page table. The method further includes enabling access permission for the first isolation domain based on the first protection key and the first extended page table, for the first application to access the memory of the first isolation domain.

Abstract: A recommendation method applied to a terminal includes a rule platform with system-level permission, the rule platform is configured to save system resources and remind a user of a function of an application. The rule platform obtains a first event and a first rule related to the first event from a rule base. The rule platform includes the rule base including a rule and each rule includes a condition. The rule platform updates a matching status of a first condition corresponding to the first event in the first rule The terminal displays a recommendation result corresponding to the first rule when a matching status of each condition in the first rule indicates that the matching is successful. The first rule is one of the rule related to the first event.

Abstract: Embodiments of this application provide a recommendation method applied to a terminal, where the terminal includes a rule platform with system-level permission, and the rule platform is configured to save system resources and remind a user of a function of an application. The method includes: obtaining, by the rule platform, a first event; obtaining, by the rule platform, at least one rule related to the first event from a rule base, where the rule platform includes the rule base, the rule base includes at least one rule, each rule includes at least one condition; updating, by the rule platform, a matching status of a first condition corresponding to the first event in the at least one rule related to the first event; and when a matching status of each condition in a first rule indicates that matching is successful, displaying, by the terminal, a recommendation result corresponding to the first rule, where the first rule is one of the at least one rule related to the first event.

Abstract: In a remote attestation procedure, an attestation report provided by a prover for a verifier includes measurement information of a target TA, where the measurement information is obtained by the prover measuring data of the target TA during running. In this way, the measurement information can indicate a status of the target TA during running. If the target TA is attacked by a malicious program during running, the measurement information may indicate that there is data related to the malicious program. In this case, after verifying the measurement information, the verifier may attest that the target TA is not securely run.
