Abstract
An example method comprises storing, in a register, an encoded pointer to a memory location, where first context information is stored in first bits of the encoded pointer and a slice of a memory address of the memory location is encrypted and stored in second bits of the encoded pointer. The method further includes decoding the encoded pointer to obtain the memory address of the memory location, using the memory address obtained by decoding the encoded pointer to access encrypted data at the memory location, and decrypting the encrypted data based on a first key and a first tweak value. The first tweak value includes one or more bits derived, at least in part, from the encoded pointer.
