The Digital Signatures

In this paper, the authors propose a solution to improve the secure of digital signature schemes, this solution is implemented on two levels of digital signature scheme construction. At the second level, the authors propose a method to construct new digital signature algorithms based on this hard problem.

This paper presents a lightweight digital signature-based routing message and node authentication solution for wireless multimedia sensor networks (WMSNs). The lightweight geographical security routing protocol (ECDSA-TPGF) is proposed on the basis of improving the original two-phase greedy geographical forwarding protocol (TPGF), in which we have added the solution Elliptic curve cryptography (ECC) and cyclic redundancy check (CRC) to create a digital signature for a sensor node attached to a routing message.

In this article, the authors propose a solution to improve the security of digital signature schemes, implemented in both levels of digital signatures. At the first level, the authors propose a new hard problem - different from the hard problems used before and hasn’t been solved by anyone so far (except by "brute force attack" method).

In this paper, we propose a design method for the signature scheme based on ring structure Zn. Our signature schemes are more secure, generate signatures at a faster rate than that of the ElGamal scheme and its variants. Moreover, our approaches also overcome some disadvantages of some similar signature schemes on ring Zn. For these advantages, they are fully applicable in practice.

Tissues are complex milieus consisting of numerous cell types. Several recent methods have attempted to enumerate cell subsets from transcriptomes. However, the available methods have used limited sources for training and give only a partial portrayal of the full cellular landscape. Here we present xCell, a novel gene signature-based method, and use it to infer 64 immune and stromal cell types.

The paper proposes a method of constructing digital signature algorithms based on the new key schemes. The new key schemes are difficult problems that currently have no solution. That algorithm construction method with a new key scheme is to improve the security of digital signature algorithms. The new method is showed through the construction of two specific digital signature algorithms and the generation of highly secure signature algorithms that are constructed by this method is completely possible.
