Public-key cryptography

in the copy, and other employee would have not had the ability to run this query. The attacker used job listing sites to narrow down what software Anthem uses to house their data; from their they used this public information to sort out over 100 employees that had access to this data. The attacker then used malware to get a hand full of employee’s credentials. Even though it is said that to keep all the personal information stored in Anthem’s computer system encrypted would have not stopped or prevented this attack because these attackers had done their research and knew what credentials they would need to perform the attack, no matter how the information was stored they still would have been able to access it. The one thing that could have been done is using cryptography for all the employee’s, especially those whom can use their credentials to perform special task.…

Symmetric Cryptography In every work station, there is a key which encrypts the data whenever shared it over the internet to another work station. Sender encrypts the data and sends it to another computer. Receiver decrypts the code with the same key. The main problem here is not with the data, but with the distribution of key. There are some problems with key sharing. In case you 're ready to give that key safely, Will the key can keep the full data safely? Each individual whom need to have…

Introduction RSA is a type of cryptography that is use for encrypting and decrypting of messages. It was created by Ronald L. Rivest, Adi Shamir and Leonard M. Adleman in the faculty of the Massachusetts Institute of Technology. RSA (Rivest, Shamir, Adleman) is named after the three inventors. RSA is still widely used for securing the confidentiality and authenticity of an e-mail. It is also use to secure communication through the internet. It is particularly useful when conducting e-commerce.…

signatures prevent persons from acting as the originator of a specific document, which is comparable to forgery on a printed text. Authentication is the primary and most critical line of defense in a system and public networks. It is now common in many stores where credit card payment can be electronically signed using a stylus. Digital signatures, however, similar to conventional signatures, can be risky; once a digital signature is exposed to the populace, it is bound to be fabricated.…

RQ 4 A one-way function is an algorithm or a function that is used to turn a piece of text into a fixed string of digits and is nearly impossible to reverse the process. In cryptography, a one-way function is used to create digital signatures which are used to identify, and authenticate the sender and the message. RQ 5 The Deffie Hellman key exchange uses the simple concept of prime numbers to generate a list of security keys for use in public…

itself. There are two key concepts in designing for testability: Controllability and Observability. Controllability refers to the ability to apply test patterns to the inputs of a sub circuit via the primary inputs of the circuit. Observability refers to the ability to observe the response of a subcircuit via the primary inputs or at some other output points. Testing requires access to the internal workings of the device under test (DUT). This is in conflict with the need for secrets to be…

computing power that renders them unrealistic for practical use. Other protocols could be useful for very small data sets but impractical for linking large databases. The techniques that are not suitable for private record linkage of large databases are: Ravikumar et al. [101], Atallah et al. [4], Freedman et al. [48], Agrawal et al. [1], O’Keefe et al. [86], and Inan [61]. 2.3.3 Secret sharing Secret sharing is required when symmetric encryption is being used between two parties to encrypt…

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…

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…

Introduction Cryptography can be defined as the process of encrypting and decrypting data in order to keep the information protected from anyone other than the two (or more) people involved in the communication. Preventing unauthorized users from being able to read the information exchanged over an insecure channel, i.e. maintaining ‘privacy’ is one serious cryptographic problem, which is why it is essential for the communicating parties to share a key that is unknown to others. This key…
