Abstract:
1. A method for generating a multi-key network address relating to a plurality of network devices, each network device in the plurality having its own public key and corresponding private key, comprising: in one of the multiple network devices: calculating a cryptographically generated identifier (cid) using the public keys corresponding to the plurality of network devices and a cryptographic hash function; applying an address generation function to the cid to create the multi-key network address; generating a message claiming the right to the multi-key address; obtaining a digital digest of the message; deriving a symmetric encryption key from the digital digest, for each public key, generating an integer x(i) using the encryption key and the public key; generating a ring signature of the digital digest using the integers x(i); and transmitting the message claiming the right to the multi-key address.
