User Authentication is defined as ‘Provision of Assurance that the message is originated from authorized user’. Message Authentication is defined as ‘Provision of assurance that the message is not altered’. Former is provided by Message Authentication codes (MAC) and later is provided by Hash functions. When MAC uses Hash function to generate authentication code it is called Hash based MAC (HMAC). In this paper a new algorithm is proposed for HMAC which uses MD5 algorithm as hash function and based on parallel processing. The algorithm is implemented using GUI based controls in MATLAB toolbox called GUIDE which enables the algorithm to be friendly with the user.Keywords

This paper deals with the implementation of security package of Hash algorithms which can be chosen by the user for their desired level of security. The concept of encryption and decryption of message is not enough for the security of data’s in current communication. Hence the concept of Message authentication is developed. One type of authentication is by Hash algorithm. Hash algorithm creates the miniature of the message. Hash algorithm takes an input message of length less than 264 (varies with the type of algorithm) and gives the output in fixed length. For the application point of view we need the comparison of their performance. Hence this paper involves the following categories.
a Implementation of MD5 algorithm
b Implementation of SHA algorithm
c Implementation of RIPEMD algorithm
d Comparison of algorithms with respect to their
a. Speed
b. Security
e Implementation of software package.

Background: Among the metal nanoparticles Zinc oxide nanoparticles have more applications in many areas, including biomedical, materials science, and environmental technology. Soybean is one of the important commercial crops due to the presence of protein, oil, carbohydrates, minerals, saponins and isoflavonoids such as genistein and daidzein.
Materials and Merhod: In this present study we synthesis the Zinc oxide nanoparticles by using glycine max seed extract. We examine the size and morphology of synthesized Zinc oxide nanoparticles by using UV-visSpectrophotometer, X-ray Diffraction (XRD).
Results: Herein, the Zinc oxide nanoparticles were synthesized by using seed extracts of glycine max with in 6h and the size of the Zinc oxide nanoparticles ranges from 70-90 and predominantly spherical shapes with crystalline nature. Elemental analysis of Zinc oxide nanoparticles was characterized by EDX.
Conclusion: The synthesized Zinc oxide nanoparticles from glycine max exhibit excellent antimicrobial activity against different clinically isolated fungi such as Aspergillus flavis, Aspergillus niger, Candida albicans, and Fusarium sp.
