(6) OAuth 2.0 Refreshing an Access Token
•Download as PPTX, PDF•
0 likes•241 views
The document discusses refreshing an access token by making a refresh request to the token endpoint with parameters including grant_type set to "refresh_token" and the refresh_token. The authorization server must authenticate the client if it is confidential, validate the refresh token, and if valid, issue a new access token and potentially refresh token while revoking the old refresh token.

(3) OAuth 2.0 Protocol Endpoints
This document describes the endpoints and parameters used in the OAuth 2.0 protocol. It outlines the authorization endpoint, which is used by clients to obtain authorization from users, and the token endpoint, which is used to exchange authorization grants for access tokens. It also discusses the redirection endpoint, used to return authorization responses to clients, and parameters like response_type, redirect_uri, client authentication, and access token scope.
OAuth1.0
The document discusses the OAuth 1.0 authentication protocol. It defines key terms like token, callback URI, OAuth signatures, and describes the OAuth authentication process. Client requests include parameters like OAuth_token and OAuth_signature, calculated using the signature base string. The server validates the signature to verify the client's identity before granting access to protected resources. Signatures can be generated via HMAC-SHA1, RSA-SHA1, or plaintext depending on the method used.
Introduction to OAuth
OAuth is an open standard for token-based authorization that allows third-party applications to obtain limited access to a user's data without requiring them to share their passwords. It allows sites to exchange user-authorized tokens that can be revoked and have varying scopes and time limits. OAuth has gone through several versions to address vulnerabilities and inconsistencies, with OAuth 2.0 simplifying the protocol through the use of bearer tokens and authorization/resource server separation. While implementations are emerging, OAuth 2.0 continues to be refined as an IETF draft standard.
(1) OAuth 2.0 Overview
OAuth 2.0 provides several authorization flows for developers including the web server flow. It has advantages like wide adoption and new authorization types but also disadvantages such as lack of interoperability between implementations and potential security issues if SSL is not used. The web server flow involves authenticating the client, obtaining an authorization code from the resource owner, exchanging the code for an access token, using the access token to access resources, and refreshing tokens as needed. OAuth 1.0 adds security features like digital signatures and nonces/timestamps but requires more complex implementation.
(2) OAuth 2.0 Client Registration
OAuth 2.0 defines client registration procedures for applications to access protected resources. Clients can register directly with the server or through self-issued or third-party assertions. Registration provides the client type (confidential or public), redirection URIs, and other info. Confidential clients like web apps store credentials securely, while public clients like native apps don't. Client identifiers uniquely identify clients without authenticating them. Confidential clients authenticate using established methods like passwords, while public clients don't authenticate.
OAuth for your API - The Big Picture
OAuth is taking off as a standard way for apps and websites to handle authentication. But OAuth is a fast moving spec that can be hard to pin down.
Why should you use OAuth and what are the business and operational benefits? What's the story with all of the different versions and which one should you choose?
Watch this webinar with Apigee's CTO Gregory Brail and Sr. Architect Brian Pagano for 'big picture straight talk' on these OAuth questions and more.
An Introduction to OAuth 2
The document provides an overview of the history and development of OAuth standards for authorization. It describes some of the issues with early implementations that prompted the creation of OAuth 1.0, including services storing user passwords and lack of ability to revoke access. OAuth 1.0 introduced signatures to address these issues. OAuth 2.0 replaced signatures with HTTPS and defines common flows for different use cases, including authorization code, implicit, password, and client credentials grants.
(4) OAuth 2.0 Obtaining Authorization
The document describes the four main grant types for obtaining authorization in OAuth 2.0: authorization code grant, implicit grant, resource owner password credentials grant, and client credentials grant. It provides details on the workflow and parameters for authorization requests and access token responses for each grant type. An extension mechanism is also described to define additional grant types using absolute URIs.

What the Heck is OAuth and OIDC - UberConf 2018
OAuth is not an API or a service: it is an open standard for authorization and any developer can implement it. OAuth is a standard that applications can use to provide client applications with “secure delegated access”. OAuth works over HTTPS and authorizes devices, APIs, servers, and applications with access tokens rather than credentials, which we will go over in depth below. OpenID Connect (OIDC) is built on top of the OAuth 2.0 protocol. It allows clients to verify the identity of the user and to obtain their basic profile information.
This session covers how OAuth 2.0 and OIDC work, when to use them, and frameworks/services that simplify authentication.

- 802.1X port-based authentication prevents unauthorized devices from accessing the network by authenticating each client connected to a switch port before allowing access.
- The switch acts as a proxy for clients and authenticates with an external RADIUS server, allowing network access after authentication and blocking access beforehand.
- Authentication is initiated by either the switch port state changing from down to up or the client sending an EAPOL-start frame, starting the exchange of EAP frames between client and RADIUS server via the switch.

OAuth 2.0 seems to be a comprehensive framework for authorizing access to protected resources, but is it really? We can argue that OpenID Connect will make it enterprise ready, but level of adoption in the enterprise is yet to be seen. This primer describes the framework fundamentals,the good, the bad, and common OAuth 2.0 flows.
OAuth 2
OAuth 2 is an authorization framework that allows applications to access user data and perform actions on their behalf. It defines flows for applications to request access, and provides short-lived credentials in response. The main roles in OAuth are the resource owner (user), client (application), resource server (API), and authorization server (issues tokens). Common grant types include authorization code, implicit, and client credentials flows. Tokens returned include access and refresh tokens, and OpenID Connect adds optional ID tokens containing user information.

It outlines the authorization code grant flow and other grant types, including how applications register and use client IDs and secrets. JSON Web Tokens are discussed as an access token format. OpenID Connect is described as extending OAuth 2.0 to provide authentication via ID tokens. Key components like access tokens, refresh tokens, and the client credentials flow are also summarized.
Oauth2 and OWSM OAuth2 support
The document discusses OAuth 2.0 and how it addresses issues with traditional approaches to authorizing third party access to user accounts and resources. It provides an overview of OAuth 2.0 concepts like authorization grants, access tokens, refresh tokens, and the roles of the client, resource owner, authorization server and resource server. It then describes the authorization code grant flow and client credentials flow in more detail through examples. The goal is to explain how OAuth 2.0 works and how it can be used to securely authorize access to resources while avoiding the risks of directly sharing user credentials.
Best Practices in Building an API Security Ecosystem
Enterprise API adoption has gone beyond predictions. It has become the 'coolest' way of exposing business functionalities to the outside world. Both your public and private APIs, need to be protected, monitored and managed.
This session focuses on API Security. There are so many options out there to make someone easily confused. When to select one over the other is always a question - and you need to deal with it quite carefully to identify and isolate the tradeoffs. Security is not an afterthought. It has to be an integral part of any development project - so as for APIs. API security has evolved a lot in last five years. This talk covers best practices in building an API Security Ecosystem with OAuth 2.0, UMA, SCIM, XACML and LDAP.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

3-6 June 2024, Niš, SerbiaTIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all
Recycled Concrete Aggregate in Construction Part II
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

(6) OAuth 2.0 Refreshing an Access Token
- 1. OAuth 2.0 REFRESHING AN ACCESS TOKEN
- 2. Refreshing an Access Token If the Authorization Server issued a refresh token to the client, the client makes a refresh request to the token endpoint with the following parameters: grant_type (REQUIRED) must be set to “refresh_token” refresh_token (REQUIRED) scope (OPTIONAL)
- 3. Refreshing an Access Token Because Refresh Tokens are long-lasting credentials, it is bound to the client to which it was issued. If the client type is confidential or has been issued client credentials, it must be authenticated with the authorization server. Example: (using TLS) POST /token HTTP/1.1 Host: server.example.com Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW Content-Type: application/x-www-form-urlencoded grant_type=refresh_token&refresh_token=tGzv3JOkF0XG5Qx2TlKWIA
- 4. Refreshing an Access Token The Authorization Server must: require client authentication for confidential clients or for any client that was issued credentials authenticate the client validate the refresh token If the Refresh Token is valid, the server issues an access token, otherwise it returns an error. The server may issue a new refresh token, in which case the client must discard the old one. The server revokes the old refresh token as well. In this case, the scope must be the same as the old refresh token
