SENSS: Security Enhancement to Symmetric Shared Memory Multiprocessors
With the increasing concern of the security on high performance multiprocessor enterprise servers, more and more effort is being invested into defending against various kinds of attacks. This paper proposes a security enhancement model called SENSS, that allows programs to run securely on a symmetric shared memory multiprocessor (SMP) environment. In SENSS, a program, including both code and data, is stored in the shared memory in encrypted form but is decrypted once it is fetched into any of the processors. In contrast to the traditional uniprocessor XOM model [10], the main challenge in developing SENSS lies in the necessity for guarding the clear text communication between processors in a multiprocessor environment. In this paper we propose an inexpensive solution that can effectively protect the shared bus communication. The proposedschemes include both encryption and authentication for bus transactions. We develop a scheme that utilizes the Cipher Block Chaining mode of the advan...
