ChipTable

This is an on-chain interim solution to ERS. It will provide a simple chip lookup table for vendors.

Design

Owner

Privileges:

• Can register TSMs
• Can add chipIds without needing signature

Data:

• address

TSM

Privileges:

• Can add chips with signature
• Can approve an operator to add chips for TSM

Data:

• tsmId: hash of the name (keccak(name))
• address: address that owns tsm
• operator: approved operator for tsm
• name: name of the tsm
• uri: redirect uri of the tsm

Chip

Data:

• tsmId: maps the chip to a tsm

Scripts

Deploy

Deploy chipTable.sol. Requires owner, version and network parameters.

Usage

node scripts/deploy-script.js -o OWNER_ADDRESS -v VERSION -n NETWORK

Register TSM

Add a new TSM. Can only be called by owner. Requires contract-address, tsm, uri and network parameters.

Usage

node scripts/register-tsm.js -c CHIP_TABLE_ADDRESS -t TSM_ADDRESS -u TSM_URI -n NETWORK

Register Chips

Add chips to chipTable. Expects a .txt file with one chip public key, 04 prepended, per line. See publicKeySamples.txt. Requires contract-address, tsm, public-key-path and network parameters.

Usage

node scripts/register-chips.js -c CHIP_TABLE_ADDRESS -t TSM_ADDRESS -p PUBLIC_KEY_LIST_FILE -n NETWORK
