Campaign of high-definition digital television: CA with card or no card – digita
Close by the end of 2009 China Digital TV The user has more than 60 million, for the entire industry and create hundreds of billions of value, but also in the great achievements hidden behind a trace of worry. As everyone knows, China Digital TV "The overall translation" mostly just the basic type one-way STB Coverage, business forms a single, content lackluster, most of the carriers is very low profitability, long-term debt management, but in net STB Confusion Gengrang operators distress, difficult to carry out new business.
In the "era of post-translation" operators to focus on the HD , Value-added, interactive, and the translation will gradually transition to the family second, and more terminals, with the continuous improvement of living standards, high definition flat panel has begun to enter the homes of ordinary people.
Other high value-added high-definition content along with the constant added, allowing operators to have a break of the predicament, an effective means to enhance profitability. However, operators also face greater security risks, safety CA Relationship digital television into China has been 10 years old, whether domestic or foreign CA CA rookie have opened the mysterious veil, in the DVB Standard definition of CA face the continuous development of the Internet, combined with the standard itself have to accept the existence of the funnel so that more serious challenges from hackers.
Operators, value-added business development direction for the future will be two-way interaction, and high-definition content will be dominated, VOD, PushVOD the conduct of such operations makes the content of their own safety is more important, how to prevent the illegal distribution of authority, how to control Play of the time, the number of CA have been beyond the traditional areas of management, and security of digital TV will gradually from the traditional to the more advanced CA CA / DRM conversion. In the CA / DRM system, the right to host the user the best carrier is the smart card, smart card manufacturing process because of its advanced, comprehensive security measures, flexible applications are widely used Financial , Insurance, telecommunications, digital television and other commercial applications. Bank of Communications in 2010, starting the New Year "Pacific smart chip debit card", the magnetic stripe and chip cards as a complex combination of cards, debit cards, compared with the traditional, IC card with higher reliability, better security, payment more convenient. In the face of a growing number of financial fraud, major banks, insurance institutions have launched "U shield" to improve online banking security, "U shield" is essentially a smart card security solutions.
Digital TV card CA is never developed from limited to non-card CA inherent security shortcomings, the global digital TV security agencies are shifting the focus to the smart card CA, addition to the smart card's security advantage, carrying capacity and flexibility of its business sex is not an insurmountable card CA, the existing non-card CA digital platform can not always get rid of "low quality cheap" bad image. Some non-card CA vendors mentioned in the CW publicity sharing is due to the loopholes created DVB standard, whether or not card smart card CA CA CW face the risk sharing, the two also support online replacement algorithm, key, in this point, both as a mother of twins with identical genetic, how to deal with all the CA will face a test. No card CA less "machine card communication" link is only to reduce the terminal for a way to CW, but if the ordinary set-top box chip, there is also the risk of interception expressly CW, some non-card manufacturers in the set-top boxes within the plug-CA one class of smart card chips, in fact, is the "smart card built-in", their safety is much lower than the special smart card can easily be cracked, copied, so no card CA had to use a set-top box chip, advanced security features (security chip) to improve the system security level. The smart card CA's security even more perfect by using "machine card cryptographic communication" to improve the hackers share threshold, followed by machine card communication, "one of a secret", "traffic control" could effectively control the hacking, the final smart card CA also supports security chip solutions. CW two in the prevention of proliferation of this point is the same starting line, and CA's security is global, not just CW proliferation risks, the physical security of the smart card chip level much higher than the level of physical security, so smart card CA has a broader range of security applications. On the other hand, the advantage of the smart card CA is the sharing of counter means, such as smart cards, "stained tracking" technology, can effectively curb the proliferation and hacking into law CW deterrent to protect the legitimate interests of the operators. CA smart card tracking technology is always hanging overhead in the hacker's "sword of Damocles," This is no card CA high security can never be achieved.
