NDSS Symposium Video: NDSS 2019 TIMBER-V: Tag-Isolated Memory Bringing Fine-grained Enclaves to RISC-V

At the Network and Distributed System Security (NDSS) Symposium 2019, 24-27 February 2019, Catamaran Resort Hotel & Spa in San Diego, California, Samuel Weiser, Mario Werner, Maja Malenko and Stefan Mangard at Graz University of Technology, and  Ferdinand Brasser and Ahmad-Reza Sadeghi at Technische Universität Darmstadt presented “TIMBER-V: Tag-Isolated Memory Bringing Fine-grained Enclaves to RISC-V.” They presented TIMBER-V, a new tagged memory architecture featuring flexible and efficient isolation of code and data on small embedded systems. In their project, they augment tag isolation with a memory protection unit to isolate individual processes, while maintaining low memory overhead. TIMBER-V significantly reduces the problem of memory fragmentation, and improves dynamic reuse of untrusted memory across security boundaries. TIMBER-V also enables novel sharing of execution stacks across different security domains, in addition to interleaved heaps. Their presentation shows the efficiency of TIMBER-V by evaluating our proof-of-concept implementation on the RISC-V simulator.
