摘要
According to one general aspect, an apparatus may include a context-specific encryption key circuit configured to generate a key value, wherein the key value is specific to a context of a set of instructions. The apparatus may include a target address prediction circuit configured to provide a target address for a next instruction in the set of instructions. The apparatus may include a target address memory configured to store an encrypted version of the target address, wherein the target address is encrypted using, at least in part, the key value. The apparatus may further include an instruction fetch circuit configured to decrypt the target address using, at least in part, the key value, and retrieve the target address.
