At present, fresh agricultural products have begun to take the scale of industrialization, the majority have been in full accordance with high yield and high quality, efficient and safe production requirements, but due to the characteristics of fresh agricultural products, more and more attention have been aroused, the traditional marketing model is facing a bottleneck, the various aspects of n...

This paper gives the first bit security result for the elliptic curve Diffie–Hellman key exchange protocol for elliptic curves defined over prime fields. About 5/6 of the most significant bits of the x-coordinate of the Diffie–Hellman key are as hard to compute as the entire key. A similar result can be derived for the 5/6 lower bits. The paper also generalizes and improves the result for ellip...

Boneh and Venkatesan have proposed a polynomial time algorithm in a non-uniform model for recovering a ”hidden” element α ∈ IFp, where p is prime, from very short strings of the most significant bits of the residue of αt modulo p for several randomly chosen t ∈ IFp. Here we modify the scheme and amplify the uniformity of distribution of the ‘multipliers’ t and thus extend this result to subgrou...

In this paper, we propose a new architectural technique to reduce energy dissipation of frame memory through adaptive bitwith compression. Unlike related approaches, the technique utilizes the fixed order of memory accesses and data correlation of video sequences by dynamically adjusting the memory bitwidth to the number of bits changed per pixel. Instead of treating data bits independently, we...

A method for creating digital image copyright protection is proposed in this paper. The proposed method in this paper is based on visual cryptography defined by Noor and Shamir. The proposed method is working on selection of random pixels from the original digital image instead of specific selection of pixels. The new method proposed does not require that the watermark pattern to be embedded in...

The memristor is promising to be the basic cell of next-generation computation systems. Compared to the traditional MOSFET device, the memristor is efficient over energy and area. But one of the biggest challenges faced with researchers is how to program a memristor’s resistance precisely. Recently, an algorithm designed to save 8 valid bits in each memristor is proposed, but this is still not ...
