High Security Level

In this paper, a novel stego-method will be introduced, which can be used to hide any secret message in any holding color image. The proposed method will be implemented and tested and the calculated parameters will be compared with the LSB method parameters. It will be shown that the proposed method provides a high-security level by using two keys to extract the secret message from the holding image, making it very difficult to hack.

Remote Sensing Methods

Remote sensing provides data that can be used in a variety of projects. One such project is the preparation for sending a manned flight to Mars. Before the departure of the expedition it is very important to carefully select a place of high scientific value and a high security level for the members of the flight. Remote sensing methods allow getting the whole set of necessary data, which will later be used for the flight equipment properly, as well as to adapt the lander design. Currently, robotic probes that send the collected information to Earth are engaged in the collection of the necessary data. There, the data, in turn, can be processed by specialists, as well as provided for the general public for informational purposes only.

High Security Level

Wireless sensor is usually tiny volume and powered by battery. So its battery capacity, CPU performance and RAM capacity are all very limited, which lead to sensor can’t afford complex encryption calculation that will cost much resource. The paper proposes a compact encryption algorithm, named CEA, which adopt minor encryption rounds, longer encryption key, improved ciphertext iteration algorithm, and cycle-exchange method to generate child-key. The measurements highly decrease the resource consumation of WSNs comparing to DES algorithm. The experiments demonstrate that the CEA algorithm owns better “avalanche effect” and high security level, furthermore, its calculation speed is far faster than DES algorithm, but cost is very low. The merits of CEA algorithm make it is more suited for resource-restrained WSNs than DES algorithm
