Two Factor Auth List. Overview After many high-profile and widespread major data breaches – which have compromised millions of people – many people have come to understand more about password security and the fact that a simple password can’t keep their online profiles safe. That has led to the rise in the popularity of two-factor authentication, an additional layer of security that can keep online accounts secure. Factors of Authentication An authentication factor is a category of security credential used to verify a user's identity and authorization before allowing that user to gain access to their account, send communications, or request data from a secured network, system, or application. There are three common factors of authentication: something you are, something you know, and something you have. Let's break them down further: Something you are. What Is Two-Factor Authentication? Two-factor authentication is a key component of cybersecurity and the work done by Cybersecurity Analysts.
What Does 2FA Mean? Platform. Before your app can use Google+ features such as creating interactive posts and fetching profile and people information, users must sign in with their Google Accounts. Set up Google Sign-In for Google+ To allow users to sign in, integrate Google Sign-In into your website. When you set up Google Sign-In for your site, also do the following: When you create your client ID, enable the Google+ API in the API Console (see Enable the Google+ API).When you configure the sign-in button, request the following scopes: If you create a sign-in button with your own assets, keep in mind the branding guidelines.
In particular, when you request social scopes, you should use a red sign-in button with the Google+ logo. Enable the Google+ API Enable the Google+ API by following these steps: Go to the Google API Console . Secure Quick Reliable Login. The first time you use SQRL the app will require you to invent a master password, from which a Master Key is cryptographically generated. This Key is a 256-bit (very very large) random number, unique and never shared. Additionally the first time using SQRL a public Identity Lock Key and a private Identity Unlock Key pair are generated via the SQRL app. The Identity Lock Key is stored alongside the Master Key but the Identity Unlock Key must be safely stored away (such as printing it as a QR code) prior to being deleted from the app.
The Identity Unlock Key is used to cancel and replace your Master Key in the event that it is compromised. When you visit a SQRL enabled website the QR code/link contains the website address and a random cryptographic challenge number. The SQRL app hashes the website address and your Master Key together to create a website unique identity. Once the signed random cryptographic challenge is verified by the website it is then able to authenticate your device. S | SQRL Secure Quick Reliable Login. The user experience: Wishing to login to an online service where an “SQRL” code appears nearby: Even though it is THAT simple, it is FARmore secure than any other login solution.
(We'll define exactly what “far more secure” means, below.) What happened behind the scenes? (This is intended to quickly inform crypto-awarereaders. Complete details are provided below.)The QR code presented near the login prompt contains the URL of the authentication service for the site. The URL includes a securely generated long random number so that every presentation of the login page displays a different QR code. Summarizing this for your next cocktail party: “The website's login presents a QR code containing the URL of its authentication service, plus a nonce.
This simple and straightforward SQRL protocolyields a surprising array of features and benefits: Anonymous Identification & Authentication: SQRL ID: Visitors to a website are uniquely identified by an absolutely anonymous SQRL ID. Yes. So what's left? Authentication - Could SQRL really be as secure as they say. Overall, the protocol does not appear to increase security over existing technology. If you are looking for the best way to protect your identity online, this is without question not it.
But let's go over the pros and cons: It's impossible to "share" a password in the narrow sense that a malicious website can't use the authentication provided to one site to log in to another site. A brute-force attack against the authentication token is not feasible. Credentials are not stored on your computer. This protects you against a small subset of workstation-directed attacks. This technique is dangerously susceptible to MITM attacks and social engineering. So, for example, a phishing site can display an authentic login QR code which logs in the attacker instead of the user.
This technique combines both authentication and identity into a physical object which is frequently lost or stolen. This technique combines all your authentication tokens into a single key unless you manually create others. Diffie–Hellman key exchange. The scheme was first published by Whitfield Diffie and Martin Hellman in 1976.[2] By 1975, James H. Ellis,[3] Clifford Cocks and Malcolm J. Williamson within GCHQ, the British signals intelligence agency, had also shown how public-key cryptography could be achieved; however, their work was kept secret until 1997.[4] Although Diffie–Hellman key agreement itself is an anonymous (non-authenticated) key-agreement protocol, it provides the basis for a variety of authenticated protocols, and is used to provide perfect forward secrecy in Transport Layer Security's ephemeral modes (referred to as EDH or DHE depending on the cipher suite).
U.S. Name[edit] In 2002, Hellman suggested the algorithm be called Diffie–Hellman–Merkle key exchange in recognition of Ralph Merkle's contribution to the invention of public-key cryptography (Hellman, 2002), writing: The system...has since become known as Diffie–Hellman key exchange. Description[edit] Illustration of the Diffie–Hellman Key Exchange , and . . SHA-1. In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard published by the United States NIST.[2] SHA-1 produces a 160-bit (20-byte) hash value. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long. SHA stands for "secure hash algorithm". The four SHA algorithms are structured differently and are named SHA-0, SHA-1, SHA-2, and SHA-3.
SHA-1 is the most widely used of the existing SHA hash functions, and is employed in several widely used applications and protocols. In 2005, cryptanalysts found attacks on SHA-1 suggesting that the algorithm might not be secure enough for ongoing use.[3] NIST required many applications in federal agencies to move to SHA-2 after 2010 because of the weakness.[4] Although no successful attacks have yet been reported on SHA-2, it is algorithmically similar to SHA-1. The SHA-1 hash function[edit] denotes addition modulo 232. or. Specifications Overview | FIDO Alliance.
The specifications are broken into two categories, U2F and UAF.

Spring Security 3 - OpenID Login with Google Provider. In this tutorial we'll add OpenID support for authenticating users in our existing Spring Security 3 application. It's required you understand how to setup a simple Spring Security application using a simple user-service. If you need a review, please read my other guide Spring MVC 3 - Security - Using Simple User-Service for an in-depth tutorial. We will use Google as our OpenID provider. You are therefore required to setup an account with Google. We will based our application from the one we developed for Spring MVC 3 - Security - Using Simple User-Service tutorial.
What is OpenID? OpenID allows you to use an existing account to sign in to multiple websites, without needing to create new passwords.You may choose to associate information with your OpenID that can be shared with the websites you visit, such as a name or email address. Here's a screenshot of the application's OpenID login page: Enabling OpenID authentication is actually simple. The Old Config spring-security.xml 1. 2. 4. 1. OpenID Foundation website.
