Architecture

Key Assignment:

Owner Key:PKo,SKo
Operator Party Key:PKp,SKp
Manufacture Key: PKm,SKm
Robot Key:PKr,SKr

Right Map

{
"Robot":"PKr",
"Role":["Owner","Administrator","Operator"],
"Owner":["CMD1","CMD2","CMD3"]，
"Administrator"：["CMD1","CMD2"]，
"Operator"：["CMD1"]，
}

Command Flow

Owner->Robot( Owner->Operator->（Check Ledger）->Ledger->Operator->Robot ）
Sign: SKo(PKp,PKr,CMD) //CMD is public unavailable

Robot->Owner( Robot->Operator->Ledger->Operator->Owner ）
Sign:SKr(PKp,PKo,Result)

Ledger Format:

 'sender': sender,
 'recipient': recipient,
 'cmd': Hash(SKo(PKp,PKr,CMD)),
 'amount':number  #Add Robot will decrease the sender's amount
