    Abstract: A server system implemented by a service provider may store health data of a user according to a multi-node data structure. The server system may generate transaction records based on requests to access the health data. Responsive to requests for the transaction records, the server system may query a database that includes the health data and generate a data package based on the querying. The data package may be sent to a requesting system. The data package may be usable by the requesting system to identify which patient profiles were accessed by which physicians.

    Abstract: A system and method for efficiently protecting branch prediction information. In various embodiments, a computing system includes at least one processor with a branch predictor storing branch target addresses and security tags in a table. The security tag includes one or more components of machine context. When the branch predictor receives a portion of a first program counter of a first branch instruction, and hits on a first table entry during an access, the branch predictor reads out a first security tag. The branch predictor compares one or more components of machine context of the first security tag to one or more components of machine context of the first branch instruction. When there is at least one mismatch, the branch prediction information of the first table entry is not used. Additionally, there is no updating of any branch prediction training information of the first table entry.

    Abstract: Some embodiments provide a method for a first device to join a group of related devices. The method receives input of a password for an account with a centralized entity and a code generated by a second device in the group. When the second device determines that the code input on the first device matches the generated code, the method receives an authentication code from the second device for authorizing the first device with the entity as a valid device for the account. The method uses the password and information regarding the first device to generate an application to the group. After sending the application to the second device, the method receives information from the second device that enables the first device to add itself to the group. The second device verifies the generated application, and the method uses the information received from the second device to join the group.

    Abstract: Techniques are disclosed relating to protecting branch prediction information. In various embodiments, an integrated circuit includes branch prediction logic having a table that maintains a plurality of entries storing encrypted target address information for branch instructions. The branch prediction logic is configured to receive machine context information for a branch instruction having a target address being predicted by the branch prediction logic, the machine context information including a program counter associated with the branch instruction. The branch prediction logic is configured to use the machine context information to decrypt encrypted target address information stored in one of the plurality of entries identified based on the program counter. In some embodiments, the branch prediction logic decrypts the encrypted target address information by performing a cipher to encrypt the machine context information and performing a Boolean exclusive-OR operation of the encrypted machine context information and the encrypted target address information.
