Native Secure Enclaved backed ssh keys on MacOS

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

async-payments user story: donation QR code

The async-payment user story I'm interested in exploring is a mobile user (not always connected) who wants to receive donations (no PoP) via a static invoice from another mobile user.

My understanding of how this could work:

  1. The static invoice should contain a blinded route to the payment receiver via their LSP and an ephemeral public key that the payment sender will use to encrypt the last hop of a payment onion containing a keysend TLV. The LSP of the payment receiver must support store-and-forward of onion messages.

  2. A payment sender builds a payment onion where the first hop is their LSP that supports trampoline payments, onion messages and async-payments. The first hop of the onion includes a TLV to indicate the payment should be held until triggered (with a async-payment nonce) and gives the blinded route to the payment receiver. The last hop of the onion is encrypted to the payment receiver's ephemeral public key and includes:

  • the keysend TLV payment secret
  • the amount being sent

Chaumian ecash designs, notes

Chaumian cash in a Bitcoin world - cashu, Fedimint

What's this for?

  • More scalable/faster than a blockchain (not enough utxos)
  • Much better privacy security model than a blockchain
  • Same or better theft security model than TTP but much worse than a blockchain

If it's so great, why hasn't it been done yet?

Visualisers of the Lightning Network (and some other explorers)

A (mostly) visual collection of the Lightning Network

Disclaimer

Network views tend to be the view of the network from a single node, or small selection of nodes. They are not complete views of the network. This is impossible to achieve. Even if many node views were combined, it would still be incomplete.

These network views, or network maps, have been termed 'visualisers' by the LN community.

Screenshots may reflect older visual styles, and are dated accordingly.
