Encryption Symmetric secret Key in Wireless Sensor Network Using AES Algorithm

      Wireless sensor network (WSN) security is an important component for protecting data from an attacker. For improving security, cryptography technologies are divided into two kinds: symmetric and asymmetric. Therefore, the implementation of protocols for generating a secret key takes a long time in comparison to the sensor’s limitations, which  decrease network throughput because they are based on an asymmetric method. The asymmetric algorithms are complex and decrease network throughput. In this paper, an encryption symmetric secret key in wireless sensor networks (WSN) is proposed. In this work, 24 experiments are proposed, which are encryption using the AES algorithm in the cases of 1 key, 10 keys, 25 keys, and 50 keys. In each experiment, two chains are combined by using a hash function (SHA-2) to produce secret keys. The Network Simulator Version 2 (NS2) was used to assess the network throughput for the generated key. The randomness of the suggested LWM method has been tested by using the Diehard statistical test and the Entropy test. The results of the tests show that the encryption secret keys have a high level of data randomness.

The effect of negation in proving the pathology of the fundamentalists

This research deals with the study of pathways in terms of the negative effect in proving them
And the fact of this influence among fundamentalists.
The research consists of two subjects and a conclusion.
In the first section, I learned about the terms in the title of the research:
Denial and pathology.
In the second section I reviewed the pathways of illness that affect exile in it
Five: the nodding, the fitting, the sounding, the division, the rotation, the inference
A description of the absence of evidence of non-reference to it. And I figured out how
Negation in it by striking some illustrative examples as fruit
Arising from the effect of negation in proving those routes.
As a result of this research, a

Efficacy of Five Organic Acids Combination on T2- Mycotoxicosis in Rats

Mycotoxins are secondary by-products of mold metabolism and are accountable for human and animal mycotoxicosis. The most serious trichothecenic mycotoxin is the fungal T-2 mycotoxin. T-2 mycotoxin impaired nutrient absorption, metabolism, and then, eliciting severe oxidoreductive stress. Diet plays a key role beyond the supply of nutrients in order to promote animal and human health. Organic acids have been commonly used to exert antioxidative stress capacity in the liver and gut ecosystem. This study is planned to explore, the competence of using (X-MoldCid®) during chronic T-2 mycotoxicosis course in rat. Rats were allocated into 4 main groups, (CN-Gr), negative control and was allowed for the free access to the normal rats chow and the

The impact of danger in the element material of the crime

The idea of ​​danger is of particular importance in the design of modern criminal Politics, especially in relation to places that are at the core of the principles of criminal legislation, which are the extent of its importance and its connection to crime and its physical structure in all its components.

             Most criminal legislation takes the danger of a Basis and a criminalization code, reflecting the criminal legislator's keenness to provide greater protection for the fundamental interests of the society. This protection is important and necessary, since it is often possible to wait for the harmful consequences of unlawful conduct.

Prevalence and pattern of endocrinological abnormalities in oligospermic and azoospermic patients.

Background: Hormones have very important role in spermatogenesis and production capacity of testis. Disturbances in their vlevels can be very crucial in dysfunction of testis which results in men infertility. This study carried out to evaluate the hormonal disturbances in men infertility and its correlation with semen parameters and types of infertility.
Patients and Methods: Blood and semen samples were collected from 91 infertile men and 20 healthy and fertile control who attended Al-Kadymiah hospital and some private clinics in Baghdad from January to December 2009.Semen and serum samples were analysed for semen parameter and FSH, LH, Testosterone and prolactin levels.

Dramatic signs of place in contemporary classical shows: كاظم عمران موسى

(The sign) was born with the birth of man, after the primitive man revealed through it the forms of speech, to express his needs and instincts, and he expressed his insides through them, through the effect of his interaction and conflict with his human counterpart on the one hand and nature on the other hand, for the purpose of communicating and communicating information, as a primitive language Indicative ...., until the linguistic language replaced it and thus signs took a further development, represented by other means that were embodied by gestures, signs and movements that took common social formulas .. such as the dances that a person practiced in his social rituals and the objective and transitional movements they contained And ge

Domestic Animals in English and Iraqi Rural Proverbs: A Pragmastylistic Study

Proverbs gain their importance not only from the fact that they represent a cultural record of the people of every nation, but they reveal the way they use language and how they exploit their environments as a good source of inspiration to enrich that language.  Domestic animals, as part of every environment, play a major role in composing proverbs in every nation.

       This study is an attempt to pragmastylistically analyse some selected English and Iraqi rural proverbs using domestic animals in their texts. It limits itself to investigate certain stylistic and pragmatic devices such as: the type of sentences, their lengths, their content and grammatical words, the part of speech used, metaph
