1. The document discusses LTE security concepts including mutual authentication between the UE and LTE network using EPS-AKA, which involves authentication vectors containing RAND, AUTN, XRES, and KASME being provided to the MME by the HSS.
2. It describes LTE authentication in three steps - transfer of authentication vectors from HSS to MME, the MME requesting authentication from the UE, and the UE responding to authenticate itself.
3. Upon successful authentication, the UE and MME share the base key KASME, which is then used to derive additional keys for NAS and AS security like integrity protection and encryption of signaling and user data.
The Long Term Evolution (LTE) is the latest step in an advancing series of mobile telecommunications systems. In this paper, authors show interest on the security features and the cryptographic algorithms used to ensure confidentiality and integrity of the transmitted data. A closer look is taken upon EPS confidentiality and integrity algorithms. The authors also defined AKA, AS and NAS security and key derivations during normal Attach process and Handover also.

The huge demand for mobile communications with broad band and usage of new wireless
applications motivated the development of new wireless access technologies. The recent
expansion of wireless technologies, novel applications and the advancement in mobile technology after UMTS-3G has been taken up to the next level by the 3GPP Long Tem
Evolution/System Architecture Evolution (LTE/SAE). It has achieved the realisation of better bandwidth, full interworking with other access/backend systems using all-IP architecture with well-defined interworking with circuit switched system. The system is defined to work across multiple access networks (3GPP and non 3GPP) may be trusted or non-trusted. The security mechanism in wireless area has evolved from original analog systems through GSM and
UMTS. The GSM has focussed the security for radio path whereas UMTS has enhanced it in to network functionalities. The future networks based on IP mechanism demands more security features, since the threats related to IP are also possible.

This paper clarifies the standards defined around LTE network security by standard development organizations including 3GPP, ITU, ETSI, and industry group NGMN. It also examines the different security borders of the mobile network, and delves deeper into the requirements of the Mobile Access Border - the border between the RAN and the core (S1).
LTE is designed with strong cryptographic techniques, mutual authentication between LTE network elements with security mechanisms built into its architecture.
With the emergence of the open, all IP based, distributed architecture of LTE, attackers can target mobile devices and networks with spam, eavesdropping, malware, IP-spoofing, data and service theft, DDoS attacks and numerous other variants of cyber-attacks and crimes.
Exploring LTE security and protocol exploits with open source software and lo...EC-Council
The security flaws of legacy GSM networks, which lack of mutual authentication and implement an outdated encryption algorithm, are well understood among the technology community and have been extensively discussed for years. However, my smartphone’s settings do not provide the means to shut down the GSM radio to prevent my phone from connecting to a potentially insecure GSM access point. Instead, I have the option to turn off LTE, the fastest mobile network.
This is not the only confusing aspect of mobile network security. Given LTE’s mutual authentication and strong encryption scheme result, there is a general assumption that LTE rogue base stations are not possible. However, before the connection authentication step, any mobile device implicitly trusts (and exchanges a substantial amount of messages with) any LTE base station, legitimate or not, that advertises itself with the right parameters. Such implicit trust and unprotected messages can be exploited to block mobile devices and track their location.
Finally, it is generally assumed that Stingrays and IMSI catchers are expensive equipment that require downgrading the connection of mobile devices to GSM. However, a basic fully-LTE IMSI catcher can be implemented by means of low-cost software radio and slight modification of a well known open-source implementation of the LTE stack.
This talk will present an exploration of the security of LTE networks, as well as experimentation results of passive eavesdropping threats, LTE protocol exploits to block mobile devices and a location leak that allows tracking mobile devices as the connection is handed off from tower to tower.

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.

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.
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.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
