DOWNLOAD EBOOKElectronic communication and financial transactions have assumed massive proportions today. But they come with high risks. Achieving cyber security has become a top priority, and has become one of the most crucial areas of study and research in IT. This book introduces readers to perhaps the most effective tool in achieving a secure environment, i.e. cryptography. This book offers more solved examples than most books on the subject, it includes state of the art topics and discusses the scope of future research.

DOWNLOAD EBOOKThe first part of this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security proofs are given. Though particular attention is given to the mathematical foundations, no special background in mathematics is presumed. The necessary algebra, number theory and probability theory are included in the appendix. Each chapter closes with a collection of exercises. In the second edition the authors added a complete description of the AES, an extended section on cryptographic hash functions, and new sections on random oracle proofs and public-key encryption schemes that are provably secure against adaptively-chosen-ciphertext attacks. The third edition is a further substantive extension, with new topics added, including: elliptic curve cryptography; Paillier encryption; quantum cryptography; the new SHA-3 standard for cryptographic hash functions; a considerably extended section on electronic elections and Internet voting; mix nets; and zero-knowledge proofs of shuffles. The book is appropriate for undergraduate and graduate students in computer science, mathematics, and engineering.

DOWNLOAD EBOOKIt’s time we cleared the air about ham radio. If you think of it as staticky transmissions sent by people in the middle of nowhere, think again. Today’s ham radio goes beyond wireless to extreme wireless, Operators transmit data and pictures, use the Internet, laser, and microwave transmitters, and travel to places high and low to make contact. In an emergency or natural disaster, ham radio can replace downed traditional communication and save lives. Whether you’re just getting turned on to ham radio or already have your license, Ham Radio for Dummies helps you with the terminology, the technology and the talknology. You discover how to: Decipher the jargon and speak the language Buy or upgrade your equipment, including the all-important antennas Build a ham radio shack, complete with the rig, a computer, mobile/base rig, microphones, keys, headphones, antennas, cables and feedlines Study for your license, master Morse code, take the test and get your call sign Understand the basics of ragchews (conversations), nets (organized on-air meetings) and DX-ing (competing in contacts to make contacts) Keeping logs with the vital statistics, including time (in UTC or World Time), frequency, and call sign Written by Ward Silver, an electrical engineer, Certified Amateur Radio License Examiner, and columnist for QST, a monthly magazine for ham operators, Ham Radio for Dummies gives you the info you need to delve into the science or dive into the conversation. It explains how you can: Tune in to the most common types of signals, including Morse Code (CW), single-sideband (SSB), FM, Radioteletype (RTTY), and data signals Break in, introduce yourself, converse, and say or signal goodbye Communicate while traveling (ham radio goes where mobile phones go dead) Register with an emergency organization such as ARES and RACES Help in emergencies such as earthquakes, wildfires, or severe weather Pursue your special interests, including contacting distant stations, participating in contests, exploring the digital modes, using satellites, transmitting images, and more Complete with a glossary and ten pages of additional suggested resources, Ham Radio for Dummies encourages you to touch that dial and take that mike. CUL. (That’s Morse Code for “see you later.”)
