Interface Design for Mapping a Variety of RSA Exponentiation Algorithms on a HW/SW Co-design Platform |
Abstract | ||
|---|---|---|
When mapping public-key algorithms, such as RSA, onto constrained devices, both efficiency and flexibility are a challenge. Because word lengths are large, minimum 1024 bits, typically a dedicated co-processor is used. On the other hand, flexibility is required, because designers want to support a variety of RSA exponentiation algorithms. Typically the solution is then a hardware/software (HW/SW) co-design platform. In this paper we have chosen this approach: we use an 8051 micro-controller for flexibility and a Montgomery multiplier for efficiency. However, the importance of the interface between HW and SW is often neglected. The main focus of this paper is therefore to propose an interface that supports maximally the flexibility and the efficiency. We use this interface to compare six different exponentiation variants of RSA with and without side-channel attack countermeasures. |
