Encryption

Everyone has secrets they want to protect. Whether it is on computers, on paper, or verbal, secret communication has been around since humans could first communicate. Cryptography is the way we can transmit secret messages so that only the person it is meant for can understand it. The art of coding and decoding messages has progressed immensely through time, and has become increasingly difficult to break with the use of technology. Cryptography’s evolution has transformed the computing world…

message of a more effective system. The news has recently been addressing the ability to break codes much more quickly than in the past because computing power and speed is continually increasing. This poses the question of why should you use an encryption? Think of Moore 's Law; the observation that, over the history of computing hardware, the number of circuits doubles approximately every two years. With this knowledge, the chip for your credit card was created, protecting your information.…

Teslacrypt (a.k.a. EccKrypt ) is a malicious program that encrypts users ' files without the knowledge or consent of the user. It falls into the sub-category of ransomware, a type of malware that encrypts the user 's files using AES encryption and forces them to pay a certain amount of money to decrypt the user 's information, essentially holding a person 's data as hostage. It first emerged around February 2015 along with its counterpart, Alphacrypt, which was released in April 2015, and it has…

Government shouldn’t have an automatic right to read anyone’s private messages/information at any time. One pro of end-to-end encryption is that data is secured when it travels from a source to its destination. It also offers high flexibility for user in selecting a data to encrypt. Another pro is that we can easily integrate with the existing solution. We can just add an encryption/decryption layer to the existing solution. One problem is that the authentication of users may be an issue. To add…

• ENCRYPTION: If the data present in the hand held devices are not encrypted, it could lead to the ePHI data that can be accessible to anyone who comes in contact with the device. • WIFI CONNECTION: Most of the hand help devices using the wifi connection provided…

The two methods steganography and cryptography can be used together. Thus it is recommended to use encryption in conjunction with steganography. 3. Motivation This research motivation came after I have studied a Computer Forensics Investigations course at Unitec Institute of Technology. The lecturer provided some useful resources to read and gain more…

Chapter 1 what is Blockchain? Basically, Blockchain is a system created essentially for the running of cryptocurrencies. Wikipedia defines a cryptocurrency as a digital asset that works as a medium of exchange and uses cryptography to secure all transactions and to control the creation of additional units of the currency. An example of such cryptocurrencies is the bitcoin. In this article, we will understand the following: • Basic meaning of blockchain • What it comprises of • How it…

Introduction Over the last couple of decades, the world as we know it has been transformed drastically. At the center of this transformation is technology, fueled by innovation and research. It is important to realize that the term technology encompasses all manner of innovations in every aspect and field of life; whether it is engineering, agriculture, manufacturing, etc. But how did the world come to be defined entirely by technology? When did this happen? A key constituent and catalyst of…

In most cases, this is recorded real communication. with a flawed encryption algorithm you can use that to break the rest of the encryption. For example: with the old pkzip encryption method. In this case if you had any of the unencrypted files in the archive, you could use that to obtain the key to break the rest. Plain text attack is the other type of attack for cryptanalysis…
