Quantum cryptography

Cryptography is a science or art that protects data and information from unwanted intruders through transforming the information to a format that is unreadable. The people with the required authentication are the only ones can read or return the data to original form. It is a system dependant mainly on the usage of a key and the main basic principle of network security. Cryptography involves plain text, which is the text that someone will type in a form that is understandable to the human. This plain text will then undergo encryption, which is a technique that converts plain text into a form that is not understandable called cipher text. The cipher will then undergo transmission towards the receiving party. A particular encoding method forms the basis for choosing series of numbers or letters that thereafter form a key. This will form the basis for encryption and…

attack for the threat actor and decrease any vulnerabilities for the defender. In the end, it is imperative that organization understand that no defense is impenetrable, but making yourself a harder target helps to minimize attacks. Quantum Cryptography Cryptography has been around for thousands of years and utilized for the transmission of secure communications between two or more individuals. However, with the emergence of quantum computing, these current cryptographic techniques might not be…

Cryptography is the study and practice of secret writing and communication. It could also be said to be art and as such provide the keys and locks of the Information Age. Secret writing developed into two different branches. One of them is steganography, derived from Greek words meaning “covered” and “to write”. Cryptography was created in parallel to this. It originates from the Greek word of kryptos meaning “hidden”. Whereas in steganography the purpose is to hide a message, so that it cannot…

The article “Quantum Computer Comes Closer to Cracking RSA Encryption” written by Amy Nordrum, shows that Cryptography needs to be important, because of the fast developing of new technology. In her article Ms. Nordrum tells about computer scientists from the MIT which found a way to crack the RSA (Rivest, Shamir and Adleman)-Code. On the fact, that RSA Encryption is used in all our devices it is quite frightening to know that the government is maybe already using this kind of technology for…

communication security. “TLS uses asymmetric cryptography to allow endpoints that have no prior relationship to securely share symmetric session encryption keys. This allows Web traffic to be secured between applications and servers, providing both confidentiality and integrity of messages on a network” (Chapple, Mike and Seidel, David, 2015, p. 279). Recommendation: Implement Virtual Private Networks Virtual Private Network (VPN) is a way to strengthen security and access resources on a network…

Video Surveillance: Effective Crime Protection Tool or Invasion of Privacy? Video cameras were seen as a great invention in technology when they were first created. They provide peace of mind for people in any area where crimes can be committed. They also provide hard evidence against people who commit certain crimes (Haering, Venetianer, and Lipton 279). In some cases, they serve as deterrents against people committing certain crimes. For example, if a shoplifter sees video cameras…

What is Cryptography? When a message is encoded so it becomes unreadable while making sure only the intended receiver is capable of decoding it back into its original form is what we commonly known as Cryptography. It is done by means of an encryption and decryption algorithm (often the same implemented in reverse order) and very often using a secret key. Some of the early cryptographic systems kept the algorithm itself secret and did not use a key (Stallings, 2014). Only when using a secret key…

Roles of Core Technologies in an Effective IT System Technology permeates all aspects of modern civilization. It is woven into the fabric of our daily lives. What was once barriers to knowledge and communication have been stripped down as we are now connected, in an instant, to the farthest reaches of the globe. With every new advancement comes an opportunity to usher in a revolution in how societies live, work, and play. The major players that make it all possible are the men and women who…

The purpose of this paper is to discuss the potential risk of connecting any computer to World Wide Web or any network. With they’re being many threats such as hackers and malicious virus’s; attacks are going to happen whether you’re an organization or just an online shopper. In this day and age it is more often that a security breach is most likely to happen on a personal computer than at a company because the home user is not as secure and the average user is not as “computer savvy”. With that…

1.2. Previous Work The first symmetric key schemes for keyword search over encrypted data are proposed in [27]. The authors consider a setting in which the sender of file encrypts each word of a file separately. Goh [15] proposed a method for secure index using Bloom filters and introduced the notion of semantic security against adaptive chosen-keyword attacks. Determining whether a file contains a keyword can be done securely in constant time. In the public key setting, Boneh et al.[5] first…
