Disclosed is a mutual authentication method and apparatus in a CAS including a headend system and DCAS host. In particular, example embodiments relate to a mutual authentication method and apparatus in DCAS, wherein the mutual authentication is performed between an authentication server of the headend system and an SM of a DCAS host, and then CAS software is downloaded to the SM. According to the example embodiments, there is provided a mutual authentication protocol between the authentication server of the headend and the SM of the DCAS host in a cable network, and also provided a mutual authentication method and apparatus in the DCAS where a substantial authentication based on a hardware, such as a smart card or a cable card, is not needed.

A mutual authentication apparatus in a Downloadable Conditional Access System (DCAS) includes an announce protocol processor to authenticate SecurityAnnounce information using an Authentication Proxy (AP) and to transmit the authenticated SecurityAnnounce information to a Secure Micro (SM), a keying protocol processor to relay KeyRequest information and KeyResponse information between a Trusted Authority (TA) and the SM in response to the SecurityAnnounce information, a decryption unit to decrypt the KeyResponse information using the SM, an authentication protocol processor to determine whether a first encryption key of the KeyResponse information is identical to a second encryption key generated by the AP, and a download protocol processor to control DownloadInfo to be transmitted from the AP to the SM, the DownloadInfo permitting the SM to download SM Client Image information.
摘要:
A mutual authentication method in a Downloadable Conditional Access System (DCAS) is provided. The mutual authentication method may receive authentication-related information about authentication between an authentication unit and a security module (SM) from a Trusted Authority (TA), generate an authentication session key using the authentication-related information, transmit the authentication session key by the authentication unit to the SM through a Cable Modem Termination System (CMTS), and control a Conditional Access System (CAS) software to be downloaded to the SM from the authentication unit, when the authentication is completed by the authentication session key.

A method of operating a Secure Micro (SM) of a host in a Conditional Access (CA) system is provided. The method includes: receiving, by the SM, a SecurityAnnounce message including a certificate of an AP server connected with a host; determining, by the SM, whether a public key stored in a memory in advance exists, and setting a flag as a first state when the public key stored in advance exists; verifying, by the SM, a digital signature with respect to the SecurityAnnounce message using the public key stored in advance; and acquiring, by the SM, another public key of the AP server by parsing the certificate and setting the flag as a second state based on whether the flag corresponds to the first state when the SM is unable to verify the digital signature.

Provided is a re-authentication apparatus in a Downloadable Conditional Access System (DCAS), the re-authentication apparatus includes: a receiving unit to receive a key request message from a Secure Micro (SM); a determination unit to determine whether to perform re-authentication depending on downloading of SM client image; an identification unit to identify an SM identifier using the key request message, when the re-authentication is performed as a result of the determination; an extraction unit to retrieve previous session information corresponding to the SM identifier and to extract keying information about the previous session information; and an encryption unit to control an encryption key about the SM client image to be reused, the SM client image being encrypted in a previous session based on the previous session information using the keying information.
摘要:
A Secure Micro (SM) copy detection system includes at least one Access Point (AP) that is connected to at least one host group including at least one SM, at least one Multiple-Services Operator (MSO) that is used to manage the at least one SM and includes the at least one AP, and a host information management server that is used to perform authentication of the at least one SM and that is independently connected to the at least one MSO.
摘要:
An apparatus and a method for providing a downloadable conditional access service using a distribution key are provided. With regard to the apparatus for providing the downloadable conditional access service using the distribution key, a subscriber authorization system transmits a target entitlement management massage being encoded with a target distribution key to a host, and the host decodes the encoded target entitlement management message being encoded with the target distribution key included in a target secure micro client.
