Variability in digital integrated circuits makes timing verification an extremely challenging task. In this paper, a canonical first order delay model is proposed that takes into account both correlated and independent randomness. A novel linear-time block-based statistical timing algorithm is employed to propagate timing quantities like arrival times and… (More)
We propose a fragile watermarking with self-embedding for recovery of tampered image that does not use authentication bits. We use a robust spread spectrum based watermarking scheme using block based embedding, DCT based compression, and other improvements. Simulation results showing recovery performance are presented.
Distributed storage systems must provide highly available access to data while maintaining high performance and maximum scalability. In addition, reliability in a storage system is of the utmost importance and the correctness and availability of data must be guaranteed. Adding parity redundancy to distributed storage systems has been problematic because of… (More)
— Elliptic Curve Cyrptography is emerging as an attractive public key cryptosystem for mobile/wireless environment. This is mostly due to the small key sizes associated with Ellip-tic Curve Cryptograhic systems. This project presents the different uses of Elliptic curve cryptography in New Generation Cryp-tosystems-the internet and in mobile computing.… (More)
