Dear Community,
I was trying to distribute the computations to 3 separate nodes, where each node receives a user's secret share in MPCTensor and an encrypted model, and returns a MPCTensor output. …

There are a few *secure* ways of generating a new share at a given index for a new party. This is useful for "repairing" a device that has lost its share or for "enrolling" a new party with a never be…

The slip39-js library provides an `encodeHex()` function for strings. It should be possible to enter any string and have it be split to shares, and be able to be recovered from shares.

To reproduce:
``` python
>>> from secretsharing import SecretSharer
>>>
>>> secret = "04bbcb1fbec99d65bf59d85c8cb62ee2db963f0fe106f483d9afa73bd4e39a8a"
>>> shares = SecretSharer.split_secret(secret, …

We haven't made much of an attempt at ensuring security and I think we should keep it that way for a while. However as we design things we should have rough security model so we avoid short cuts that …

Notes from today's experiments:
1. It's possible to add/remove members with share encryption keys in public recovery
2. That's because it is possible to re-key and re-share the recovery ledger sec…

I suggest adding shamir's secret sharing scheme as described [Satoshi Labs's SLIP0039](https://github.com/satoshilabs/slips/blob/master/slip-0039.md)
My idea is to introduce command that generates …

As per [this discussion](https://github.com/microsoft/CCF/pull/5655#issuecomment-1725428036), the current secret re-assembly only attempts to use the first `threshold` shares passed to it (*).

# Background
Recently, we've discussed at length how we might improve the performance of the platform, while not compromising security. One of the more obvious levers to pull is to improve the perf…
