Steganography, or data hiding is the technique of embedding a message (pay¬load) in a medium (carrier), without causing suspicion about the existence of hidden data in the medium. The perturbations to the medium are carried out in such a manner that there is no perceivable noise component introduced. One way to illustrate the concept of steganography would be to analyze the Sim¬mons’ Prisoners’ problem. Two prisoners are allowed to communicate through a medium via an agent trusted by the warden.…

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 encryption and decryption.…

IV Methodology The AES algorithm has 4 phases that execute the process in sequential manner. The encryption process is achieved by processing plain text and key for initial and 9 rounds, Same decryption is takes place but in reverse manner. A 4x4 state is formed in each round and particular length data is introduced in it for encryption process.The 10, 12, 14 rounds are there for 128, 192,256 bits in length respectively. Initially a key expansion process is used to expand the basic 16 byte key…

I am going to start out by apologizing because this is going to be long. But I believe everything I say is worthy of saying so I hope you don’t just give up and stop reading. I am a person that doesn’t particularly like school. Something about being stuck in a classroom for seven hours and force fed facts I don’t always want to learn just has me counting down the days till summer. So are there things I would change about the school system? Yes. Is there an aspect I wouldn’t change about the…

Private schools have more enriched opportunities like Advanced Placement courses, exchange programs and International Baccalaureate programs with access to experienced tutors that are more equipped to help the student on account of being familiar with its rising popularity and workings. AP courses and IB programs…

In the spring of 2009, more than one million high school students took Advanced Placement (AP) exams. Since it began in the 1950s, the AP program has allowed numerous high school students across the United States to take many of their high school courses at a college level stature. At the end of each course, students then take comprehensive exams to test their knowledge in order to earn college credit. While there are those who contend that the AP program has some positive aspects, many people…

few of the many questions that run through a teacher 's head when he or she is selecting a novel for their AP English Class. AP stands for Advanced Placement, and the whole objective of an Advanced Placement English Class is to give students a glimpse of what a college class is like, but more so to prepare them for the Advanced Placement English Exam. The Advanced Placement English Exam is given in May to students who have completed the AP Class in English. This exam is about three hours long;…

The effects both the positive and negatives of the AP (Advanced Placement) classes that high school students partake in each year to earn a college credit before ever leaving high school is a huge issue for most promising young scholars. In…

What is standard care? Standard care is a measure of what the community expects and demands from a person from a person in a given situation (Varone, 2012). There are two types of standard care, ordinary and professional. Ordinary standard care is the degree of care that the reasonably prudent person would not run would have exercised under the circumstances and professional standard care is the care that a person with professional skills and training is required to exercise, namely, the care…
