Building the digital tachometer came out successfully as we saw in the data & observations section. The video showed the circuit with a computer fan interrupting the emitter/detector circuit which sent rising edge signals of +5v to the microcontroller. The LCD output the proper value from the rpm counter corresponding to the fan's current speed and it was accurate! One additional thing I did do to verify, was capture the pulse frequency on an oscilloscope and make sure it matched up with the LCD's RPM data which it did. ....etc

Abstract: Cryptography's aim is to construct schemes or protocols that can still accomplish certain tasks even in the presence of an adversary. A basic task in cryptography is to enable users to communicate securely over an insecure channel in a way that guarantees their transmissions' privacy and authenticity. Providing privacy and authenticity remains a central goal for cryptographic protocols, but the field has expanded to encompass many others, including e-voting, digital coins, ....etc

In today's commercial environment, establishing a framework for the authentication of computer-based information requires a familiarity with concepts and professional skills from both the legal and computer security fields. Combining these two disciplines is not an easy task. Concepts from the information security field often correspond only loosely to concepts from the legal field, even in situations where the terminology is similar. For example, from the information security point of view, digital signature means the result of applying to ....etc

Digital Signature

Abstract :

The authenticity of many legal, financial, and other documents is determined by the presence or absence of an authorized handwritten signature. The recipient of the signed document can verify the claimed identity of the sender using the signature. Also, if the sender later repudiates the contents of the document, then recipient can use the signature to prove the validity of the document.

With the computerized message systems replacing the physical transport of paper and ink documents, an effective s ....etc

In paper based financial messaging system, the messages are sent in defined formats duly signed by the authorized signatories. Paperless initiative and changes in the business practices have changed the authorization process. In electronic messaging, the messages are created, authenticated electronically and sent through electronic medium. Present technology facilitates data transmission with security integrity duly taking care of confidentiality and nonrepudiation of messages. Encryption and digital signature play a vital role in providing suc ....etc
