Robust Key Exchange Protocol between Set-Top Box and Smart Card in DTV Broadcasting
Secure communication between set-top boxes (STBs) and smart cards is directly related to the benefit of the service providers and the legal rights of users, while key exchange is the essential part of a secure communication. In 2004, Jiang et al. proposed a key exchange protocol for STBs and smart cards based upon Schnorr’s digital signature protocol and a one-way hash function. This paper, how...

متن کاملSecure Communication in Digital TV Broadcasting
To provide subscription-based Digital TV (DTV) data, services providers scramble the data stream (program content) with some secure measures such as ECM and EMM via using control words, and send the stream to conditional access system (CAS) in the set-top box (STB). Smart card is used to decrypt the control words and accordingly to enable the STB to descramble the scrambled signal. Therefore, s...
متن کاملSecure Key Exchange Scheme for IPTV Broadcasting
In Internet Protocol Television (IPTV) broadcasting, service providers charge subscription fee by scrambling the program in Conditional Access System (CAS). This avoids unauthorized users to receive the programs. A smart card (CA card) is used to decrypt the Control Words (CWs) and transfer them back to Set-Top Box (STB) in order to descramble the scrambled program. This paper presents a secure...
