Cryptography
A broad introduction to cryptography what it is, how it really works, what its future holds, and why every informed citizen should understand its basics. We all keep secrets from our gym locker codes to our email passwords to our online interactions. And we choose to share those secrets only with those whom we trust.So, too, do organizations, businesses, governments, and armies.In this fascinating book Cryptography, Panos Louridas provides a broad and accessible introduction to cryptography, the art and science of keeping and revealing secrets.Louridas explains just how cryptography works to keep our communications confidential, tracing it back all the way to its ancient roots.Then he follows its long and winding path to where we are today and reads the signs that point to where it may go tomorrow. A few years back, interest in cryptography was restricted to specialists.Today, as we all live our lives attuned to our digital footprint and the privacy issues it entails, it becomes more and more essential to have a basic understanding of cryptography and its applications to everyday life.Starting with classical cryptography, Cryptography takes the reader all the way up to the twenty-first century cryptographic applications that underpin our lives in the digital realm.Along the way, Louridas also explains concepts such as symmetric cryptography, asymmetric cryptography, cryptographic protocols and applications, and finally, quantum and post-Quantum cryptography as well as the links between cryptography and computer security.

What is options trading?
Options trading is a type of investing strategy that involves buying and selling options contracts on the stock market. An options contract gives the holder the right, but not the obligation, to buy or sell a specific asset at a predetermined price within a set timeframe. Options trading allows investors to speculate on the direction of a stock's price movement without actually owning the stock itself. It can be a high-risk, high-reward strategy that requires a good understanding of the market and careful risk management.

Cryptography Made Simple
In this introductory textbook the author explains the key topics in cryptography.He takes a modern approach, where defining what is meant by "secure" is as important as creating something that achieves that goal, and security definitions are central to the discussion throughout. The author balances a largely non-rigorous style — many proofs are sketched only — with appropriate formality and depth.For example, he uses the terminology of groups and finite fields so that the reader can understand both the latest academic research and "real-world" documents such as application programming interface descriptions and cryptographic standards.The text employs colour to distinguish between public and private information, and all chapters include summaries and suggestions for further reading. This is a suitable textbook for advanced undergraduate and graduate students in computer science, mathematics and engineering, and for self-study byprofessionals in information security.While the appendix summarizes most of the basic algebra and notation required, it is assumed that the reader has a basic knowledge of discrete mathematics, probability, and elementary calculus.
