I am interested in new memory safety hardware. Investigating Google pixel. ARM has some nice things like MTE and PAC, but what of this new Titan chip? Pixel style? Anyone have a link to useful resource on mechanisms?

yeah, so security based on obscurity doesn’t work? he he he. great work by research crew!!!!

MTE can be used to implement many deterministic guarantees. Using the 4-bit random tags as a probabilistic bounds/temporal safety feature isn't all that it can do. If the tags were dramatically larger it could be used for a full inter-object memory safety implementation for C.
