Introduction to Secure Socket Layer (SSL) and Tunnel Layer Security (TLS). Shows basic principle of SSL and also little bit of practical applicability.
SSL is an acronym for Secure Sockets Layer. It is a protocol used for authenticating and encrypting web traffic. For web traffic to be authenticated means that your browser is able to verify the identity of the remote server.

Adonis Fung and I worked on a project where we defined and built PKI (Public Key Infrastructure) for our local development and deployed environments. I gave a talk to our engineers on how PKI works, covering encryption, signing, trust stores, and how the HTTPS handshake works.
IPsec provides the capability to secure communications across a LAN, across private and public WANs, and across the Internet. Examples of its use include:
Secure branch office connectivity over the Internet
Secure remote access over the Internet
Establishing extranet and intranet connectivity with partners
Enhancing electronic commerce security
Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. This presentation is made as an assignment during our university course.
Transport Layer Security (TLS) is a protocol that ensures privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message. TLS is the successor to the Secure Sockets Layer (SSL).

Stands for "Secure Sockets Layer." SSL is a secure protocol developed for sending information securely over the Internet. Many websites use SSL for secure areas of their sites, such as user account pages and online checkout. Usually, when you are asked to "log in" on a website, the resulting page is secured by SSL.

Explain how SSL protocol is used to ensure the confidentiality and integrity of the Internet traffic.
Solution
SSL uses a combination of public-key and symmetric-key encryption to secure a connection between two machines, typically a Web or mail server and a client machine, communicating over the Internet or an internal network.
Using the OSI reference model as context, SSL runs above the TCP/IP protocol, which is responsible for the transport and routing of data over a network, and below higher-level protocols such as HTTP and IMAP, encrypting the data of network connections in the application layer of the Internet Protocol suite. The \"sockets\" part of the term refers to the sockets method of passing data back and forth between a client and a server program in a network, or between program layers in the same computer.
The Transport Layer Security (TLS) protocol evolved from SSL and has largely superseded it, although the terms SSL or SSL/TLS are still commonly used; SSL is often used to refer to what is actually TLS. The combination of SSL/TLS is the most widely deployed security protocol used today and is found in applications such as Web browsers, email and basically any situation where data needs to be securely exchanged over a network, like file transfers, VPN connections, instant messaging and voice over IP.
The SSL protocol includes two sub-protocols: the record protocol and the \"handshake\" protocol. These protocols allow a client to authenticate a server and establish an encrypted SSL connection. In what\'s referred to as the \"initial handshake process,\" a server that supports SSL presents its digital certificate to the client to authenticate the server\'s identity. Server certificates follow the X.509 certificate format that is defined by the Public-Key Cryptography Standards (PKCS). The authentication process uses public-key encryption to validate the digital certificate and confirm that a server is in fact the server it claims to be.
Once the server has been authenticated, the client and server establish cipher settings and a shared key to encrypt the information they exchange during the remainder of the session. This provides data confidentiality and integrity. This whole process is invisible to the user.
For example, if a webpage requires an SSL connection, the URL will change from HTTP to HTTPS and a padlock icon appears in the browser once the server has been authenticated.
The handshake also allows the client to authenticate itself to the server. In this case, after server authentication is successfully completed, the client must present its certificate to the server to authenticate the client\'s identity before the encrypted SSL session can be established.

Good programmers write code that humans can understand- well, that is called clean code. This is code that other developers can easily read, understand, and add to.
Developers often rush to code when they feel the pressure from the client or manager or deadline, sometimes sacrificing the quality. Every year, a tremendous amount of time and significant resources are lost only because of poorly written code.
This slide focuses on the types of programming, definitions of clean code, characteristics of clean code, examples and how to write those.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
