Elliptic curve cryptography is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography is the same level of security provided by keys of smaller size.
Elliptic curves are applicable for encryption, digital signatures, pseudo-random generators and other tasks. They are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic curve factorization.

CLASSICAL ALGEBRAIC IWASAWA THEORY.
JOHN COATES
If one wants to learn Iwasawa theory, the starting point has to be the basic
material covered in §1 - §8 of Iwasawa’s paper [1]. The aim of these lectures will
be to give a concise account of this work, concentrating on proving one of the
main results of the paper, which is the so called weak Leopoldt conjecture for the
cyclotomic Zp-extension of any number field, i.e. that the p-adic defect of Leopoldt
is always bounded as one goes up the cyclotomic Zp-extension. The course will also
include a brief introduction to the notion of the Iwasawa algebra of Zp, and the
structure theory of modules for this Iwasawa algebra. The background required for
the lectures will be basic algebraic number theory, including a knowledge of the
main facts of abelian global class field theory.

CTF cryptography challenges are often provided with an encoded message and some hint as to the encoding. Advanced challenges will often be misconfigured or poorly implemented encryption algorithms.

What is EPHEMERAL KEY? What does EPHEMERAL KEY mean? EPHEMERAL KEY meaning - EPHEMERAL KEY definition - EPHEMERAL KEY explanation.

A cryptographic key is called ephemeral if it is generated for each execution of a key establishment process. In some cases ephemeral keys are used more than once, within a single session (e.g., in broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is combined separately with each recipient's public key. Contrast with a static key.
Private ephemeral key agreement key: Private ephemeral key agreement keys are the private keys of asymmetric key pairs that are used only once to establish one or more keys (e.g., key wrapping keys, data encryption keys, or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors).
Public ephemeral key agreement key: Public ephemeral key agreement keys are the public keys of asymmetric key pairs that are used in a single key establishment transaction to establish one or more keys (e.g., key wrapping keys, data encryption keys, or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors).

Here's Fermat's original proof. See the drawing that was too large to fit into margin
.https://www.youtube.com/watch?v=wFyX5uqyLLA&t=157s
I am looking for someone to helpo write proof of beawl conj3ecture. there is a 1 $1,000,000 prize.
This proof has been verified by a former professor of mathematics at Harvard. I am presenting this video in order to get any possible objections.
http://en.wikipedia.org/wiki/Square_root_of_2 Here is one use of irreducible fractions to prove square root of 2 is irrational.
October 23, 2013 The view count is now over 1200. No person has come forth with a counter proof in the last 200 views. So my proof must be correct. Sept. 23, 2013I was waiting until the view count reached 1000 to make this statement, but the statement at 960 view count (September 28, 2013) spurred me to make it now. No one has been able to disprove the Theorem and there has been attempts to disprove the proof that were incorrect. So, I am making the challenge that the proof is correct. There have been a number of people that have read the proof but have been afraid of saying the proof is correct. That includes Sean Gomes. Even the mathematicians at Chapman University have been silent on the veracity of the proof. David B. Moore has tried several times to get faculty to respond, with no success. You can call him at 714-516-4590 to verify this for yourself.
Ferrmat's Dilemma The problem with this proof is that it may be possible for the larger denominator that makes the presumed smallest ratio for the rational number, in front of the term (x^n-1 + y^n-1), divides into this term perfectly. So which number is the real ratio? Is the proof really dependent on the language used? This question is what prompted Fermat to go on to prove the case for n=4, I am sure.
August 16, 2013 Dear reader
Look at what Sean Gomes has written about you
"Youtube is not a system for peer review. That is like asking a deaf man to distinguish mozart from cannibal corpse."
All you have to do to prove him wrong is to invoke social media intelligence. retweet this link or post on facebook, etc.
This is a solution using infinite descent along with Diophantine equations, a technique used by Fermat in many other theorems. This probably is the proof that he thought of, and it only uses very simple math.
I prayed to God for the answer for the proof. He has delivered once again. This time I am remembering that he did it.
July 17, 2013
My friend, Mike Slack, mentioned that I misused the term 'infinite descent in the proof. I did go back and check and the term was misused. Fortunately, infinite descent is not used in the proof. In thinking back on this mistake, I think I was seeing how Fermat started looking at this as a possible path to proof with infinite descent and discovered that the square of factor was double that of the calculated rational ratio, like I did.Thanks to Mike, I am able to explain this inconsistency.
If you get smarter like I did, here is a video on how to do it.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure mathematics devoted primarily to the study of the integers. German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." Number theorists study prime numbers as well as the properties of objects made out of integers (for example, rational numbers) or defined as generalizations of the integers (for example, algebraic integers).
Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (for example, the Riemann zeta function) that encode properties of the integers, primes or other number-theoretic objects in some fashion (analytic number theory). One may also study real numbers in relation to rational numbers, for example, as approximated by the latter (Diophantine approximation).
The older term for number theory is arithmetic. By the early twentieth century, it had been superseded by "number theory". (The word "arithmetic" is used by the general public to mean "elementary calculations"; it has also acquired other meanings in mathematical logic, as in Peano arithmetic, and computer science, as in floating point arithmetic.) The use of the term arithmetic for number theory regained some ground in the second half of the 20th century, arguably in part due to French influence. In particular, arithmetical is preferred as an adjective to number-theoretic.
