CaSE- Cache-Assisted Secure Execution on ARM Processors

CaSE- Cache-Assisted Secure Execution on ARM Processors

Learn about CaSE (Cache-Assisted Secure Execution), a framework designed to protect sensitive code and data on ARM processors against both software attacks and hardware memory disclosure attacks like cold boot attacks. Explore how this 23-minute IEEE conference talk combines ARM TrustZone and Cache-as-RAM techniques to create an isolated execution environment that encrypts applications in memory and decrypts them only within the processor. Discover the implementation details on an ARM Cortex-A8 processor, including the use of cache locking, self-modifying programs, and performance impacts on cryptographic algorithms like AES, RSA, and SHA1.
