Question about cryptographic security rules ?

[prodnet]

Hello,

Your secret sharing codes around meet the cryptographic security rules ?
Some details like : integrity checks and side-channel resistance

Recommandations :

*Be side channel resistant (timing, branch, cache)
*Secure the shared secret with a MAC
*Use the platform (OS) randomness source

**These slip-ups can often fully compromise the security of the scheme.

Hello @prodnet. Thank you for drawing attention to these important aspects. The repo contains algorithms. They achieve the goal of the algorithm as described in every research work they are based on. There were no additional effort to make it resistant to side-channel attacks or to add integrity check.

I added a note, please see c59272d

If you can help make the code secure against attacks, contributions are welcome.
