CAS System Diagram
• Multi-layer encryption keys cialis • Key words updating randomly(5 to 10s), key updating control(send EMM by air)
• Upgrading the Lot number of cards by air:
• Broadcasting transmission orders、delete pirate card、close IC card orders.
• Valid period control of authorization information to prevent subscribers’ watching from overdue authorization
• Reasonable authorization system and safety strategy to against hackers attacks.
• No in-break record in hundreds of cases worldwide
• Highest security level smart card
• Security certified level is EAL 5+
• Internal use firewall、EEPROM protection、data encryption etc.
• Using common encryption algorithm and compunicate encryption algorithm to ensure data transmit safety.
• Code applications and algorithm downloading

In order to meet the demand of radio and television operators higher levels of data security transmission, calculate tong company launched a new high security technology, security chip solution, completely.
put an end to the illegal sharing of scrambling program. High security chip is the main principle in smart card settlement building secure transport channels between one chip, scrambling of smart card output control word (the CW) after high-level encryption algorithm encryption into security chip, the chip inside complete decryption reconciliation, completely shut down illegal embezzler, clear the window of the CW. At the same time, each smart card with only one Set-top Box chip pins binding through security, make a set-top box output ciphertext the CW in other STB box security chip is unable to decrypt, effectively guarantee the operators high security of data transmission.
