    摘要: Methods, systems, and computer readable media can be operable to facilitate the encryption of a device identifier using an identification property of a SoC. A unique identifier of a cable modem may be encrypted using a unique key or other unique property of a SoC associated with the cable modem. When an authentication process is initiated at the cable modem, the encrypted unique identifier of the cable modem may be decrypted using the unique key or other unique property of the SoC, thereby producing the unique identifier of the cable modem. The decrypted unique identifier of the cable modem may be output from the cable modem to an upstream controller during the authentication process. In embodiments, an obfuscation key may be used to encrypt and decrypt the unique identifier of the cable modem, and the obfuscation key may be generated using a unique identifier of the SoC.

    摘要: A method for anonymizing user identifiable information to be transmitted outside of a local network includes generating a network entity hash input based on (i) a first MAC address assigned to a client station of the local network, (ii) a second MAC address assigned to the network gateway device of the local network, and (iii) an identifier of a cloud entity of an external network to which data of the client station is to be transmitted. The method further includes generating a hash value output based on the network entity hash input and a random token value using a hashing function, generating an anonymized MAC address associated with the client station based on the hash value output, and transmitting the anonymized MAC address associated with the client station to the cloud entity of the external network.

    摘要: A method of securely accessing a modem is disclosed that uses an authentication token with a hash of a secure shell server (SSH) public key. The method includes receiving an encrypted authentication token from the modem, the authentication token having one of a hash of the SSH public key and the SSH public key and being encrypted according to another public key, transmitting the encrypted authentication token to a central server, receiving a decrypted authentication token from the central server, the decrypted authentication token comprising the hash of the SSH server public key, configuring modem interfaces at least in part using the authentication token, the modem interfaces including an interface with an SSH server, and communicating with the modem according to the hash of the SSH server public key.

    摘要: A method is provided for remotely and securely accessing a modem is provided that uses an encrypted authentication token with a modem password. The method includes receiving an encrypted authentication token from the modem, the authentication token having a modem password stored in secure memory and being encrypted according to a public key, transmitting the encrypted authentication token to an authentication server. receiving a decrypted authentication token from the authentication server, the decrypted authentication token comprising the modem password, generating an authentication key and a privacy key from the modem password, configuring modem interfaces at least in part using the authentication token, the modem interfaces including a network management protocol interface and communicating with the modem using the network management protocol interface according to at least one of the generated authentication key and the privacy key.
