Exploring Low Cost Optimal Watermark for Reusable IP Cores During High Level Synthesis

Abstract: The challenges in the current design process for consumer electronics products include greater complexity and stiff time-to-market pressure, which has led to the usage of reusable intellectual property (IP) cores (such as JPEG and MPEG) as a sustainable solution. This has led to the domain of IP protection for anti-piracy as an important subject of research for a system design. Watermarking is expected to provide the best protection of authorship when applied at higher levels, i.e., during high-level synthesis. It is also well acknowledged that watermark insertion is non-trivial, as it is very difficult to choose a strong signature that results in higher security and less area overhead among available design solutions. This paper presents a novel multi-variable signature encoding for embedding a dynamic watermark in an IP design during architectural synthesis that provides enhanced security against typical attacks. Owing to the involvement of multiple (four) variables in the proposed signature, it is difficult to realize the signature without complete encoding knowledge of the four variables. Second, our approach aims to optimize the embedding cost of the watermark by exploring a low-cost solution through particle swarm optimization-driven design space exploration based on area-delay constraints. Comparison with a recent technique indicated that our watermark incurs lower embedding cost, lower runtime, and less storage hardware.

FDI and Innovation: An Investigation into Intra- and Inter-industry Effects

Abstract: It is often believed that transfer of technology and know-how resulting from foreign direct investment (FDI) goes beyond the actual projects undertaken by foreign investors and, spills over to domestic firms affecting their knowledge base and productivity. This paper is an endeavour to investigate the existence of spillovers and their impact on the innovative performance of domestic firms active in the manufacturing sector of India. By employing data on FDI by industry and merging it with information on time-variant buyer–supplier linkages obtained from a series of national input–outputs tables, the study develops intra-industry and inter-industry measures to capture the effects of FDI on innovation performance of the incumbent firms’ active in the same sector as the MNC and in upstream and downstream sectors. The econometric analysis after accounting for endogeneity issues reveals that FDI has a moderate impact on innovative performance of firms residing in identical industries. However, impact o...
