This document provides an overview of cryptography basics, including symmetric and asymmetric cryptography. Symmetric cryptography uses the same key for encryption and decryption, with examples being AES, DES, and stream ciphers. Asymmetric cryptography uses public/private key pairs, with common algorithms being RSA for encryption and DSA for digital signatures. The document also discusses key management, certificates, email security protocols like S/MIME and PGP, network security protocols like TLS/SSL, and technical considerations for cryptographic choices.
a message digest is a cryptographic hash function containing a string of digits created by a one-way hashing formula. Message digests are designed to protect the integrity of a piece of data or media to detect changes and alterations to any part of a message. In this paper, we have explained the hashing algorithm of MD5 and also proposed how to use it for file transmission and for hashing any string.

All you need to know about transport layer securityMaarten Smeets
Many people think that using HTTPS to offer your site or service to clients makes you secure from eavesdroppers and people trying to manipulate your network traffic. Think again! In this presentation I'll dive into transport layer security. I'll elaborate on what you can achieve with SSL such as authentication, encryption and integrity and how you can achieve it. I'll talk about the client-server handshake, identity and trust, one-way and two-way SSL, keys and keystores and cipher suite choice. By means of several examples, I'll show what it can mean if you make the wrong choices in on premises and cloud scenario's. This presentation is relevant for anyone involved in securing connections between client and server using TLS and people interested in learning more about the topic of TLS in general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.

34. Cryptography Technical Choices
Use a hash when you want a way of verifying that data has not been
tampered with in transit.
Use a keyed hash when you want to prove that an entity knows a secret
without sending the secret back and forth, or you want to defend against
interception during transit by using a simple hash.
Use encryption when you want to hide data when being sent across an insecure
medium or when making the data persistent.
Use a certificate when you want to verify the person claiming to be the owner
of the public key.
Use symmetric encryption for speed and when both parties share the key in
advance.
Use asymmetric encryption when you want to safely exchange data across an
insecure medium.
Use a digital signature when you want authentication and non-repudiation.
Use a salt value (a cryptographically generated random number) to defend
against dictionary attacks.
