  Computing-in-memory (CIM) is proposed to alleviate the processor-memory data
transfer bottleneck in traditional Von-Neumann architectures, and
spintronics-based magnetic memory has demonstrated many facilitation in
implementing CIM paradigm. Since hardware security has become one of the major
concerns in circuit designs, this paper, for the first time, investigates
spin-based computing-in-memory (SpinCIM) from a security perspective. We focus
on two fundamental questions: 1) how the new SpinCIM computing paradigm can be
exploited to enhance hardware security? 2) what security concerns has this new
SpinCIM computing paradigm incurred?
