摘要： A method includes encrypting a first message that contains a first public key of a first peer, by using a second public key of a second peer; and decrypting a second message sent from the second peer by using a first private key paired with the first public key. The second message may be encrypted at the second peer by using the first public key, and may contain an encrypted data encrypted by the second peer using the second public key and hashed by using a secret key of the first peer. The first public key, the second public key, the first private key and the secret key may be physically unclonable function (PUF)-based keys.

摘要： A method includes encrypting a first message that contains a first public key of a first peer, by using a second public key of a second peer; and decrypting a second message sent from the second peer by using a first private key paired with the first public key. The second message includes a write command and is encrypted at the second peer by using the first public key, and contains an encrypted data encrypted by the second peer using the second public key and hashed by using a secret key of the first peer. The first public key, the second public key, the first private key and the secret key are physically unclonable function (PUF)-based keys.
