1. A computing device to secure indirect addresses, the computing device comprising:
one or more memory devices;
a processor coupled to the one or more memory devices, wherein the processor includes address encoding logic to:
receive, from a computer program, a request to allocate a block of memory of the one or more memory devices to the computer program;
determine, in response to the request, an indirect address to the block of memory;
encode, in a subset of the indirect address, metadata indicative of access permissions to the block of memory; and
provide the indirect address to the computer program.
