Language used: VB script It’s a simple code written in notepad‚ which can encrypt and decrypt text that can be sent as secret message. First line in the code creates a dialogue box that asks for a text to encode. Submitted text is then reversed. Next the %windir%\notepad opens up an instance of Notepad to print the results after waiting for 1 second. Then a function is written that encodes the text by advancing each character by 3 letters. Same procedure is followed in the decryption code.

Although Zigbee implements a wide assortment of security measures‚ there are still a variety of vulnerabilities and attack methods that can be used. These attacks and how they can be carried out will be described in this Section. The first and possibly easiest attack to implement is the denial of service attack. These types of attacks overload the network such that service is denied to the network’s end users. In a typical wired network this is accomplished by having a huge number nodes simultaneously

ABSTRACT “3d Password” Usually the authentication scheme the user undergoes is particularly very lenient or very strict. With all the means of technology developing‚ it has become very easy for others to fabricate or to steal identity or to hack someone’s password. Users nowadays are provided with major password stereotypes such as textual passwords‚ biometric scanning‚ tokens or cards (such as an ATM) etc .Mostly textual passwords follow an encryption algorithm. Biometric scanning is your "natural"

A Privacy Leakage Upper-Bound Constraint Based Approach for Cost-Effective Privacy Preserving of Intermediate Datasets In cloud ABSTRACT Cloud computing provides massive computation power and storage capacity which enable users to deploy computation and data intensive applications without infrastructure investment. Along the processing of such applications‚ a large volume of intermediate datasets will be generated‚ and often stored to save the cost of re-computing them. However‚ preserving

Keeping Research Confidential At ABC Institute of Research‚ the value of the company is in the confidentiality of what it finds. If for example‚ ABC were to expend a great investment in finding a solution to a problem‚ only for DEF Research Inc. to discover their secret‚ ABC could suffer greatly. In the current age of networks and computers‚ the information you put in is only as safe as you make it. In order for ABC Institute of Research to keep their investment safe‚ they must protect their

The Enigma Code was a method of encryption created using the Enigma Machine to encrypt and information or messages. The Enigma machine was first invented by Arthur Scherbius at the end of world war I and was used commercially throughout the 1920s until it was adopted by multiple governments during WWII‚ including Germany‚ Japan‚ and Italy. This had allowed the Axis powers to safely and efficiently communicate sensitive information‚ but polish mathematician Marian Rejewski was able to break the code

INTRODUCTION: Blowfish‚ a symmetric block cipher developed by Bruce Schneier[SCHN93‚ SCHN94)‚ is a Feistel network‚ iterating simple encryption and decryption functions of 16 times each. The block size is 64 bits‚ and the key can be any length up to 448 bits. Although there is a complex initialization phase required before any encryption can take place‚ the actual encryption of data is very efficient on large microprocessors. Blowfish was designed to have the following characteristics: Fast:

There are two basic types of encryption; asymmetrical and symmetrical. Asymmetrical uses two keys; a public and a private key. The public and the private keys have unique characteristics. In asymmetric encryption you can encrypt with a public key that has a matching private key used for decryption. The other basic type of encryption is called symmetric encryption; the main difference between the two is that symmetrical encryption uses only one key; a private key used for both encryption and decryption
