SCA3S: target implementation harness

Acting as a component part of the wider SCARV project, SCA3S is a collection of resources that support the development and analysis of cryptographic implementations wrt. side-channel attack: SCA3A is, more specifically, pitched as offering "side-channel analysis as a service": it allows users to acquire and analyse side-channel data-sets which stem from execution of their implementation, without (necessarily) owning or operating the associated infrastructure. Mirroring the goals of SCARV, it places particular emphasis on analogue side-channels (e.g., power and EM) stemming from RISC-V-based platforms. The main repository acts as a general container for associated resources; this specific submodule houses a harness within which target implementations are developed.

Quickstart (with more detail in the wiki)

1. Either

   1. provide a native build context by installing associated pre-requisites, e.g.,

      • a suitable compiler and programming tool-chain, e.g., board-specific versions of GCC and OpenOCD,
      • the Doxygen documentation generation system,

      and/or

   2. provide a Docker build context by installing the Docker container platform.

2. Follow the recommended workflow, which, roughly speaking, involves the following steps:

   1. enroll (via the SCA3S web-based interface),
   2. create user repository,
   3. clone user repository,
   4. develop target implementation,
   5. build target implementation,
   6. commit target implementation,
   7. use target implementation.
