Most of the existing crypto drivers cannot operate effectively over the multi-core systems, resulting in high synchronization overheads. Moreover, the crypto drivers under utilize the full capacity of the hardware device underneath, resulting in low IPsec throughput. This paper discusses a design methodology that virtualizes the access to the common crypto accelerators across the multiple cores and...
In this paper a Joint Perceptual Encryption and Watermarking scheme (JPEW) has been proposed. The technique has been incorporated in the JPEG compression standard. Perceptual Encryption is required in many of the multimedia content preview applications. On the other hand, watermarking is used to ensure the integrity of the multimedia content. There is always a need of an efficient technique that reduces...
Mobile agent is a suitable paradigm to collect information from multiple sites in a distributed environment. As compare to other technologies, mobile agents can be used beneficially for Automatic Meter Reading (AMR) and to measure power quality information at each energy meter. Since meter contains embedded system, so the choice of agent platform for such an application is very important. This article...
Embedding maximum information in a stego-image with minimum change in its appearance has been a major concern in image-based steganography techniques. In this paper, we present a strategy of attaining maximum embedding capacity in an image in a way that maximum possible neighboring pixels are analyzed for their frequencies, to determine the amount of information to be added in each pixel. The technique...
