摘要： A method, computer program product, and data processing system for executing larger-than-physical-memory applications while protecting sensitive program code (and also data) from unauthorized access in a memory space not subject to protection fault or page fault detection are disclosed. Large applications are accommodated by providing a mechanism for secure program overlays, in which a single large application is broken into two or more smaller applications (overlays) that can be executed from the same memory space by overwriting one of the smaller applications with another of the smaller applications when the latter needs to be executed. So that the data may be shared among these smaller applications, each of the applications contains embedded cryptographic keys, which may be used to encrypt or decrypt information to be stored persistently while control is transferred from one application to the other.

摘要： A method of invoking power processor element (PPE) serviced C library functions on a synergistic processing element (SPE) running in isolated mode. When the SPE initiates a PPE-serviced function, an SPE stub routine allocates a parameter buffer in an open area of a local store (LS) memory within the SPE. The LS memory includes an open area accessible to the PPE, and an isolated area inaccessible to the PPE. The SPE stub routine copies function parameters corresponding to the PPE-serviced function to a buffer within the open area of the LS memory, and writes a message word, which contains an identification variable of the PPE-serviced function and a location variable of the function parameters, to the open area. When execution is temporarily suspended on the SPE, the PPE reads the message word from the open area of the LS memory and executes the PPE-serviced function.

摘要： A method, computer program product, and data processing system for protecting sensitive program code and data (including persistently stored data) from unauthorized access. Dedicated hardware decrypts an encrypted kernel into memory for execution. When an application is to be executed, the kernel computes one or more secrets by cryptographically combining information contained in the application with secret information contained in the kernel itself. The kernel then deletes its secret information and passes the computed secrets to the application. To store data persistently in memory, the application uses one of the computed secrets to encrypt the data prior to storage. If the kernel starts another instance of the same application, the kernel (which will have been re-decrypted to restore the kernel's secrets) will compute the same one or more secrets, thus allowing the second application instance to access the data encrypted by the first application instance.

摘要： A method, computer program product, and data processing system are disclosed for ensuring that applications executed in the data processing system originate only from trusted sources are disclosed. In a preferred embodiment, a secure operating kernel maintains a “key ring” containing keys corresponding to trusted software vendors. The secure kernel uses vendor keys to verify that a given application was signed by an approved vendor. To make it possible for independent developers to develop software for the herein-described platform, a “global key pair” is provided in which both the public and private keys of the pair are publicly known, so that anyone may sign an application with the global key. Such an application may be allowed to execute by including the global key pair's public key in the key ring as a “vendor key” or, conversely, it may be disallowed by excluding the global public key from the key ring.
