OUR FUTURE COLLABORATION
Within an R&D team specializing in embedded systems security, the objective of this internship is to build a unified test vectors generator for a cryptographic hardware IP.
This IP is a smart DMA, which in addition to DMA capabilities is able to perform cryptographic operations (symmetric cryptography, hash computation, asymmetric cryptography…). These operations are executed through dedicated programs loaded in a system memory.
To verify the features of the smart DMA, test vectors are loaded in memory, and contain: specific instructions encoding the cryptographic operations, input data, and expected output data. The verification must ensure that the output data obtained in simulation are identical to the expected ones.
Generating these test vectors is made complex by the wide variety of features that are supported by the IP, so the objective is to automate the generation.
Using an interface to be defined, the generator should let the user (among other features):
Select a cryptographic algorithm
Select mode of operation (for example for AES) or specific instruction to test
Choose relevant sizes (key size, operand size, message length…)
Choose if test vectors should use random data of specific known data
Once the use case is defined, the tool should generate the memory content to be loaded. Expected output data would be generated based on input data provided and using existing libraries or scripts as reference.
The generator should be an abstraction layer between the user and this variety of reference scripts (written in C, Python, Sage…).
YOUR PROFILE
4th or 5th year of Master’s Degree in Computer Science
