This presentation provides a cohesive overview of the work performed by AIS, Inc. on the DARPA CFT MoRE effort. MoRE was a 4-month effort which examined the feasibility of utilizing TLB splitting as a mechanism for periodic measurement of dynamically changing binaries. The effort created a proof-of-concept system to split the TLB for target applications, allowing dynamic applications to be measured and can detect code corruption with low performance overhead.
