Attribute-based access to scalable media in cloud-assisted content sharing. age, nationality, or gender) rather than an explicit list of the consumers' names. The scheme is efficient and flexible because MCP-ABE allows a content provider to specify an access policy and encrypt multiple messages within one ciphertext such that only the users whose attributes(More)
Herein, we report a successful application of molecular modeling techniques to design two novel peptides with cytotoxicity on tumor cells. First, the interactions between the nuclear transport factor 2 (NTF2)-like domain of G3BP and the SH3 domain of RasGAP were studied by a well-designed protocol, which combines homology modeling, protein/protein docking,(More)
This paper describes a secure and synthesis ophthalmology telemedicine system, referred to as TeleOph. Under a Secure Socket Layer (SSL) channel, patient prerecorded data can be safely transferred via the Internet. With encrypted videoconference and white-board, the system not only supports hospital-to-clinic consultation, but also supplies(More)
SVC (Scalable Video Coding) is designed to adapt to heterogeneous networks and various terminal devices. This paper presents an encryption scheme for SVC bitstreams which retains the valuable scalability properties of SVC. To this end, we explore PACSI (Payload Content Scalability Information) and RTP (Real-time Transport Protocol) payload format such that(More)
Taking advantage of the inter-layer prediction technique used in H.264/scalable video coding (H.264/SVC), in this paper we propose an efficient block-based encryption scheme (BBES) for encrypting H.264/SVC enhancement layers (ELs). BBES operates in three modes, namely, Intra-MB mode, Group-MB mode and 4Group-MB mode. All the three modes are effective in(More)
