In order to fight against severe risks of security and privacy for implantable medical devices, an on-chip security guard based on zero-power authentication is proposed and verified in this paper. The conception of ‘zero-power’ is realized by virtue of wireless power recovery instead of fetching power from primary battery. The security guard recovers both data and clock from external wireless signals...
Seamless Video Service is a new service mode, providing video services to users at any time and any place. In seamless content delivery system, the authentication & authorization protocol is an essential problem to be solved. In this paper, an authentication & authorization protocol suitable for seamless video services with light weight certificate, namely SVSAAP is proposed. Through the analysis...
In the Pay-TV system, the Key Management System (KMS) is one of the essential basis. The KMS is used to prevent the unauthorized access to the audio/video data and ensure the benefit of the service providers. The security of the KMS is primarily affected by the key distribution process. In this paper, a distributed key management scheme based on the notion of the rekey path method is proposed. Through...
In this paper, we proposed a DRM authentication scheme with smart-card. We first defined a three-role based DRM implementation scenario (server, playback device and smart-card), and then fully considered its security and performance challenges. Our scheme is based on identity based encryption and it's implementation-oriented. The scheme is efficient at server-side and compact in smart-card design...
In this paper, we propose a novel three party authentication scheme which could realize the mutual authentication among the involved parities (service provider, terminal and smart-card), and our scheme can be used for more fair-use oriented DRM scheme framework design. The scheme is highly efficient and secure, and it's immune to many existing attacks.
In this paper, we redefine the roles in Mobile-TV systems from two parties(service provider and user) to three par-ties(network operator, content provider and user). Afterwards, we concentrate our discussion on service authentication problem in three-party model. Our proposed scheme is based on Identity Based Encryption(IBE) scheme, give a novel way to solve the mutual authentication and batch authentication...
