Analyzing The Three Types Of Cryptography

Md. Rule 5-901(b)(4); cf. Fed. R. Evid. 901(b)(4) (“The appearance, contents, substance, internal patterns, or other distinctive characteristics of the item, taken together with all the circumstances.” (emphasis added)). Maryland Rule 5-901 illustrates how the internal features of a document can be significant support for establishing the authenticity of that document, so long as there is some extrinsic circumstance that makes those internal features

Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.

A one-time pad is a encryption technique that utilises random letters combined with the plaintext to create a cipher text. For decryption you must have the original one time pad. Unbreakable if done properly.

When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:

It allows in a case For investigators to and hidden or deleted storage/information and help prevent or catch criminal acts.

Objective 3 – A system that can ensure the safety of data from other possible circumstances that may result to corruption and loss of data.

Moreover, encryption requires use of a key or cipher, which is used to lock and unlock the hidden data. Such a key is necessary to allow the hidden data to be viewed in an intelligible manner by those who are authorized to view it. However, there is always a risk that the encryption key might fall into the wrong hands, thereby allowing the information to be accessed by unauthorized viewers.

a) A PKI (public key infrastructure) enables users of a basically unsecure public network such as the Internet to securely and privately exchange data and money through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority.

There’s two types used in encryption, there’s the public key which is used to encrypt the information you trying to send. There is also the private key which is used to decrypt the message. The public and private key is used in many things for example emails and telephones. The reason why it’s so important that these two keys are used is because the message you’re sending stays between you and the receiver, therefore the message will not get interrupted by an invader.

A science vital in modern, everyday life. A word unknown to many. Key in both the winning of the Revolutionary War and World War II. Used for security, communication, authentication, and encryption. Runs not only the digital world, but cars, medical devices, and drones. What is this unheard science? This hidden word? Cryptology.

This report illustrates the Message Digest 6 (MD6) hashing algorithm, how it functions, and the essentialness of a hashing function. Besides, it depicts the qualities of this hashing capacity over its predecessor, and its present shortcomings.

Before approaching Claude Shannon’s contribution to Cryptography, one must look at his prior work in particular in the field of information theory, a field he theorized in his 1948 paper A Mathematical Theory of Information. Shannon introduced a lot of the ideas that were mentioned and developed in this revolutionary paper to the scientific community in his 1945 paper entitled A Mathematical Theory of Cryptography.

Authentication is the only method which protects information or data of an individual or organization from a second party to access. Based upon the confidentiality of that particular data or information, the level of authentication depends. Now-a-days, all this data and information what we are talking about is getting digitized all around the world. For this digitized data or information to be secure, a proper authentication procedure must be set. This arise the need for an authentication secret which belongs to the category “Something we know” to come into picture. These secrets authenticate each secret holder as the authorized legitimate user to access their particular account. Technology is

Information collected digitally from computers or media storage applications has protocols that need be followed during the process. The order of collecting digital information mostly determines the life expectancy of information collected (Eoghan, 2004, p. 74). There is a need to change information

Asymmetric key system (or asymmetric algorithm; public key): A cryptographic system that uses two separate keys: one key to encrypt and a different key to decrypt information. These keys are known as public and private
