Quantum cryptography

In this case which involves an active warden, however, the message needs to look innocuous and hence cryptography fails. Steganography comes to the price¬owners, rescue. The prisoners’, with a strong intention of planning an escape, have already exchanged a code word before they were captured. They use this codeword to secretly exchange messages in the process…

2 DESCRIPTION OF THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data…

1. Message confidentiality means that a message being sent cannot be read by anyone other than the intended recipients, and message remains confidential and it cannot be read by unauthorized ones. Integrity defines the process of data is modified based on cryptographic procedures like hashing and message code techniques that ensures the message is not modified. A message which is encrypted that is modified in transmitting can't be determined the original text, but rather will not have integrity…

The word cryptography can be split into pieces in order to better understand the word. The first part of the word cryptography, Crypto-, means “concealed, secret, hidden.” Graphy-, derived from the Greek word graphikos, means “of or for writing, belonging to drawing, picturesque.” (Online Etymology Dictionary) Put together, the word cryptography means “the process of writing or reading secret messages or codes” (Merriam-Webster…

Identify strategies to control and monitor each event to mitigate risk and minimize exposure Identify at least two types of security events and baseline anomalies that might indicate suspicious activity. One type of a security event that might indicate supicious activity is an authentication failures found in audit logs. Audit logs contain a high volume of events so particular attention on which events that should be specifically tracked and managed require consideration. An audit log can…

Emerging Technologies in Greener Networks Name Institution Emerging Technology Emerging technology refers to technology that has the capacity to either refine the existing technology enabling it to be better or using the existing technology as a basis for evolution in technology (Rotolo, Hicks, & Martin, 2015). New technology may result from a number of changes for example the convergence of previously separate technologies to create one new technology or the divergence of previously…

WBAN or Wireless Body Area Network is a new technology that has been invented for monitoring health condition of an individual. This is fitted in the body of a person Wire Sensor Network or WSN is possible due improvement of sensor technology as well as computer miniaturization. As the data related to patients are stored in a WBAN it is imperative that security of the data must be maintained. Body Area Network is a system comprising of wireless network of sensors to monitor health designed for…

M5A1 Short Paper: Encryption and Firewalls Questions 1. Was the firewall and Web server used by Linen Planet providing encryption services? If so, what kind of protection was in place? 2. How could the access to Linen Planet’s Web server have been better secured? Padma Santhanam, the CTO of Linen Planet, is traveling to work and get an urgent request to log in to the work order system and approve the change request (Whitman & Mattord, 2010). If this is not done they will miss the window for…

Digital Signature are used in network security are as follows: Application of digital signature is on the upward push because of the reality of felony and technological developments, alongside with authorities initiated solid market demand for secured transactions on the Internet. Digital signature capacities contain encoding messages such that totally authentic parties are in a part to decrypt the message. Two separate however interrelated 'keys' perceived as public key and Privet key elevate…
