Digital signatures use public and private key cryptography to provide the security of a handwritten signature for digital documents. The sender uses their private key to encrypt a hash of the message, creating a digital signature. The receiver can then use the sender's public key to decrypt the signature and verify that it matches a hash of the received message, proving it came from the sender and was not altered. Digital signatures authenticate the sender and ensure integrity of the message. They prevent repudiation of signatures but reliance on private keys means signatures are suspect if a private key is compromised.
This document discusses digital signature schemes. It begins by introducing cryptography and defining cryptosystems. It then describes private and public key cryptosystems. Digital signatures are introduced as a technique for non-repudiation based on public key cryptography. The properties and types of digital signatures are outlined, including direct and arbitrated signatures. Common digital signature standards like DSS, El Gamal, and RSA are then explained at a high level. The document concludes that digital signatures provide an effective mechanism for authenticity and non-repudiation of messages.
Blockchain is a distributed ledger that records transactions in blocks that are linked using cryptography. Each node maintains a copy of the blockchain. Key concepts include:
- Public key cryptography allows nodes to verify transactions without revealing identities.
- Smart contracts enable decentralized applications to execute transactions and store data on the blockchain without an intermediary.
- The Ethereum blockchain supports a Turing-complete scripting language to build decentralized applications with more complex functionality than Bitcoin. It uses ether as its internal currency and charges gas fees to compensate for usage.
An introductory look at various Blockchain Technologies and examples. In this slide I explain about basics of Etherium and types of Blockchain technology currently present and some known public projects/examples which use Blockchain.
Securing Application Deployments in CI/CD Environments (Updated slides: http:...Binu Ramakrishnan
In a multi-tenant CI/CD environment, developers trust and delegate CI/CD systems to deploy their applications to production. But, what is the basis of this trust? How the trust is enforced from commit-to-deploy? What is the trustworthiness of the application deployed by CI/CD through automation? This talk highlights security risks with CI/CD deployments and offer solutions to mitigate those risks

The colours that dresses your brand are playing an important role in how they support this personality that you want to portray. Don’t panic when a colour speaks one thing, but in the relation to the brand it delivers a slightly different response.
Check out these examples of how brands used in conveying their message through branding and banner advertisement.

17 Ways to Design a Presentation People Want to ViewJim MacLeod
Tired of boring PowerPoint presentations? Me too. Here are 17 tips to help you create a presentation that not only engages the audience, but forces them to remember what you want them to remember.
We suddenly live in a strange and wonderful nexus of digital and physical. Touchscreens let us hold information in our hands, and we touch, stretch, crumple, drag, and flick data itself. Our sensor-packed phones even reach beyond the screen to interact directly with the world around us. While these digital interfaces are becoming physical, the physical world is becoming digital, too. Objects, places, and even our bodies are lighting up with with sensors and connectivity. We’re not just clicking links anymore; we’re creating physical interfaces to digital systems. This requires new perspective and technique for web and product designers. The good news: it’s all within your reach. With a rich trove of examples, Designing for Touch author Josh Clark explores the practical, meaningful design opportunities for the web’s newly physical interfaces.
