Introduction to Cryptography
Cryptography is a technique of secure communications that allows a particular sender and intended recipient of a message to view its contents. The term is obtained from the Greek word “Kryptos”, which means “hidden, secret”. More generally, cryptography is about establishing and analyzing protocols that avert third parties or the public from reading personal messages. Moreover, it works on the various aspects of information security such as data confidentiality, data integrity, authentication, and non-repudiation.

Introduction to Cryptography
Cryptography is a technique of secure communications that allows a particular sender and intended recipient of a message to view its contents. The term is obtained from the Greek word “Kryptos”, which means “hidden, secret”. More generally, cryptography is about establishing and analyzing protocols that avert third parties or the public from reading personal messages. Moreover, it works on the various aspects of information security such as data confidentiality, data integrity, authentication, and non-repudiation.
Cryptography is the practice of securing communication through encryption and decryption techniques to transmit information secretly. There are three eras in the history of cryptography: the manual era, mechanical era, and modern era. The main types of cryptography are encryption, which locks up information, and decryption, which unlocks encrypted information. Cryptography uses keys, either symmetric keys where the same key encrypts and decrypts, or public key cryptography which uses two separate keys - a private key and public key.
Cryptography is the science of using mathematics to encrypt and decrypt data to enable secure storage and transmission of sensitive information. It involves using a key to convert plaintext into ciphertext that can only be read by the intended recipient. There are two main types: symmetric key cryptography which uses the same key for encryption and decryption and is faster, and asymmetric key cryptography which uses two different keys and is more secure but also more complex. Cryptography ensures confidentiality, authentication, integrity, access control and availability of data through techniques like substitution and transposition ciphers.
Encryption works uses symmetric key encryption where each computer has a secret key to encrypt data before sending. It also uses public key encryption with a private and public key, where the private key is known only to the computer and the public key is given to others. SSL and TLS use public key encryption to securely transmit sensitive information over the internet, replacing HTTP with HTTPS and displaying a padlock icon.
Cryptography is the science of securing communication and information by transforming messages into an unreadable format. The document discusses the origins and evolution of cryptography from ancient hieroglyphs to modern ciphers like the Enigma machine. It outlines the main purposes of cryptography as authentication, data confidentiality, integrity and non-repudiation. The key types are described as secret key cryptography, public key cryptography and hash functions. Applications of cryptography include authentication, digital signatures, time stamping and secure network communications.
Encryption works by converting plain text data into an encrypted cipher using cryptography and mathematical functions, making the data unreadable to anyone except authorized parties. It is used to securely store, hide, and transmit sensitive information like passwords, credit card numbers, and personal data online to protect against unauthorized access during transmission. Proper encryption ensures that only those meant to decrypt the message can while establishing the legitimacy and complexity of the encryption method used.
This document discusses the importance of cryptography and PKI for ensuring security, privacy, and authentication in digital communications. It addresses the three main goals of cryptography - confidentiality, integrity, and availability. The document then provides an overview of cryptographic algorithms, including symmetric and asymmetric encryption as well as hash functions. It also discusses common cryptanalytic attacks and how the strength of encryption increases exponentially with longer key sizes, making brute-force attacks infeasible for sufficiently long keys.
Cryptography is the process of securing communication and information by converting plain text into cipher text using cryptographic algorithms and keys. There are two main types: symmetric key cryptography which uses a single private key for encryption and decryption and is faster but less secure, and asymmetric key cryptography which uses two different keys (public and private) and is more complex but more secure. The purpose of cryptography is to defend against hackers and securely transmit sensitive information such as financial transactions, intellectual property, and other private communications.
PKI uses asymmetric encryption where a user has a private key to encrypt and a public key for others to decrypt. A PKI infrastructure issues digital certificates containing a user's public key signed with the private key of a certificate authority. Components include a PKI server, USB tokens to generate and store key pairs, and mobile apps. Risks include compromise of the certificate authority's private key allowing impersonation of any user. Hardware tokens are more secure than mobile PKI in terms of tamper resistance and standards compliance.
Encryption works by using keys to scramble data so it can only be read by authorized parties. There are two main types: symmetric key encryption which uses the same key to encrypt and decrypt, and public key encryption which uses separate public and private keys. Secure Socket Layer (SSL) and Transport Layer Security (TLS) are commonly used protocols that ensure sensitive data transmitted on the internet is securely encrypted.
Computer encryption uses cryptography to secure online transactions. There are two main types of encryption: symmetric-key encryption where both computers share the same key, and public-key encryption which uses different keys for encryption and decryption. Encryption encodes data during transmission while authentication verifies the identity of the sender and confirms the data has not been altered. Together, encryption and authentication create a secure online environment for sharing information.
Blockchain technology is a distributed ledger platform that provides open and transparent transaction information with integrity and non-repudiation based on modern cryptography. It is also the technology behind many cryptocurrencies. This presentation will give fundamental knowledge on how blockchain works, its cryptography implementation, cryptocurrency definition and related terms and also blockchain use cases.
The document provides an overview of blockchain technology, including its key components and how it works. In 3 sentences:
Blockchain is a distributed ledger of transactions stored in encrypted blocks that are chained together, with each new block recording transactions and a hash of the previous block. The blockchain is maintained through a consensus mechanism where participants validate transactions and add new blocks to the chain in a decentralized manner. The document discusses the technical aspects of blockchain like transactions, blocks, consensus algorithms, mining and validation, as well as its applications across different industries.
Deja vu Security - Blockchain Security Summit - Adam CecchettiScott Strang
Adam Cecchetti, CEO of Deja vu Security, discusses building security into blockchain technologies. Early ledger technologies from 5000 years ago provide context for modern blockchains. Blockchains face challenges with privacy, forging records, and scalability similar to early computers. Enterprise blockchains like Quorum and Hyperledger aim to solve these issues by making transactions private and permissioned through consensus algorithms instead of mining. Building security into decentralized applications and smart contracts is important as blockchains are still new computing platforms facing classic security problems.

This introductory session for the security model of blockchain will cover the 101 of blockchain technology, how transactions work and the use of cryptography for securing the distributed ledger, private and public keys, multisignature and review one of the hacks Ethereum has been exposed to, the parity wallet hack.
Blockchain uses cryptography, distributed computing, and game theory to allow transactions to be recorded in a distributed ledger called a blockchain. The blockchain uses cryptography techniques like hashing and digital signatures to ensure security and integrity of data. Blockchain networks have different types of nodes, including full nodes that store the entire blockchain and partial nodes that only store necessary parts. Consensus mechanisms like proof-of-work are used to validate transactions and add new blocks to the distributed ledger.
DApps, or decentralized applications, are the most common acronym. Let's begin by stating that dApps have recently become a prominent trend in the app market. Then why are dApps so prevalent? Just now, we described how these applications are built with the help of a blockchain dApp development company. Given the benefits of this technical foundation, it is highly probable that all industries will rapidly adopt it. Let's examine the functionality of these applications in greater depth.

A toxic combination of 15 years of low growth, and four decades of high inequality, has left Britain poorer and falling behind its peers. Productivity growth is weak and public investment is low, while wages today are no higher than they were before the financial crisis. Britain needs a new economic strategy to lift itself out of stagnation.
Scotland is in many ways a microcosm of this challenge. It has become a hub for creative industries, is home to several world-class universities and a thriving community of businesses – strengths that need to be harness and leveraged. But it also has high levels of deprivation, with homelessness reaching a record high and nearly half a million people living in very deep poverty last year. Scotland won’t be truly thriving unless it finds ways to ensure that all its inhabitants benefit from growth and investment. This is the central challenge facing policy makers both in Holyrood and Westminster.
What should a new national economic strategy for Scotland include? What would the pursuit of stronger economic growth mean for local, national and UK-wide policy makers? How will economic change affect the jobs we do, the places we live and the businesses we work for? And what are the prospects for cities like Glasgow, and nations like Scotland, in rising to these challenges?
"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.
