How to add external libraries to TEE and provide TA to the code for calling #6572

Closed oldoldcoder closed 8 months ago

oldoldcoder commented 8 months ago

Hello,experts:

I try to use tee to complete the Paillier semi-homomorphic encryption algorithm. Since the general implementation of this algorithm is based on GMP and NTL, two libraries related to large number operations, my questions are as follows:

  1. How to place these library files in the TEE test to ensure that my TA uses the relevant data structures without errors.
  2. I need to modify those makefiles

Thanks for your reply, salute to you!

If you intend to upstream this somewhere please give a few more details of what you have in mind. If not: 1: No special place is needed, perhaps close to the TA would make sense 2: You're probably better off starting from scratch using a sub.mk file, compare with how lib/libmbedtls is compiled.

Have you successfully implemented GMP compilation into TA on your end? How is the process implemented? Can you provide a complete compilation process?
