Abstract
A computer system configured to enhance data protection. A computer system includes one or more clients, such as processing subsystems and a memory subsystem interconnected via a network. Transactions within the system may involve the separation of data and a corresponding address in both space and time. At various points in the system, operations may be performed which seek to reunite a data and corresponding address, such as a store operation. In order to further ensure the correspondence of data and an address which is to be used in an operation, clients are configured to generate and utilize an additional symbol. The symbol is generated at least in part on an address which corresponds to data. The symbol is then associated with the data and serves to represent the corresponding address. The symbol may then be utilized by various clients within the system to check an address which is proposed to be used in an operation with the data.
