What is CRYPTOGRAPHIC ACCELERATOR? What does CRYPTOGRAPHIC ACCELERATOR mean? CRYPTOGRAPHIC ACCELERATOR meaning - CRYPTOGRAPHIC ACCELERATOR definition - CRYPTOGRAPHIC ACCELERATOR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In computing, a cryptographic accelerator is a co-processor designed specifically to perform computationally intensive cryptographic operations, doing so far more efficiently than the general-purpose CPU. Because many servers' system load consists mostly of cryptographic operations, this can greatly increase performance. Intel's AES-NI is by far the most common cryptographic accelerator in commodity hardware. VIA PadLock is another recent example. Several operating systems provide some support for cryptographic hardware. The BSD family of systems has the OpenBSD Cryptographic Framework (OCF), Linux systems have the Crypto API, Solaris OS has the Solaris Cryptographic Framework (SCF) and Microsoft Windows has the Microsoft CryptoAPI. Some cryptographic accelerators offer new machine instructions and can therefore be used directly by programs. Libraries such as OpenSSL and LibreSSL support some such cryptographic accelerators. Almost all Unix-like operating systems use OpenSSL or the fork LibreSSL as their cryptography library. These libraries use cryptographic accelerators such as AES-NI if available.

Cryptography for JavaScript Developers - Nakov @ JS.Talks() 2018
Title: Cryptography for JavaScript Developers Speaker: Svetlin Nakov, PhD Conference: js.talks() 2018 Most developers believe they know cryptography, just because they store their passwords hashed instead of in plaintext and because have once configured SSL. In this talk the speaker fills the gaps by explaining some cryptographic concepts with examples in JavaScript. The talk covers: - Hashes, HMAC and key derivation functions (Scrypt, Argon2) with examples in JavaScript - Encrypting passwords: from plain text to Argon2 - Symmetric encryption at the client-side: AES, block modes, CTR mode, KDF, HMAC, examples in JavaScript - Digital signatures, ECC, ECDSA, EdDSA, signing messages, verifying signatures, examples in JavaScript - Why client-side JavaScript cryptography might not be safe? Man-in-the-browser attacks, Cross-Site Scripting (XSS) / JavaScript injection, etc. More info, slides and video: http://www.nakov.com/blog/2018/11/18/cryptography-for-javascript-developers-nakov-js-talks-2018/

HeartBleed Hacking with Metasploit and nmap Test
Heartbleed is a security bug in the open-source OpenSSL cryptography library, widely used to implement the Internet's Transport Layer Security (TLS) protocol. This vulnerability is due to a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension. A fixed version of OpenSSL was released on April 7, 2014, at the same time as Heartbleed was publicly disclosed. At that time, some 17 percent (around half a million) of the Internet's secure web servers certified by trusted authorities were believed to be vulnerable to the attack, allowing theft of the servers' private keys and users' session cookies and passwords. The Electronic Frontier Foundation, Ars Technica, and Bruce Schneier all deemed the Heartbleed bug "catastrophic". Forbes cybersecurity columnist Joseph Steinberg wrote, "Some might argue that [Heartbleed] is the worst vulnerability found (at least in terms of its potential impact) since commercial traffic began to flow on the Internet HOW TO DO?

The Hidden World of Crypto - The Linux Cryptography API Part I
The Linux kernel has a rich and modular cryptographic API that is used extensively by familiar user facing software such as Android. It's also cryptic, badly documented, subject to change and can easily bite you in unexpected and painful ways. This talk will describe the cryptography API, provide some usage example and discuss some of the more interesting in-kernel users, such as DM-Crypt, DM-Verity and the new file system encryption code. Slides available at: https://www.slideshare.net/kerneltlv/linux-kernel-cryptographic-api-and-use-cases Gilad Ben-Yossef is a principal software engineer at ARM. He works on the kernel security sub-system and the ARM CryptCell engine. Open source work done by Gilad includes an experiment in integration of network processors in the networking stack, a patch set for reducing the interference caused to user space processes in large multi-core systems by Linux kernel “maintenance” work and on SMP support for the Synopsys Arc processor among others. Gilad has co-authored O’Reilly’s “Building Embedded Linux Systems” 2nd edition and presented at such venues as Embedded Linux Conference Europe and the Ottawa Linux Symposium, as well as co-founded Hamakor, an Israeli NGO for the advancement for Open Source and Free Software in Israel. When not hacking on kernel code you can find Gilad meditating and making dad jokes on Twitter.

[GreHack 2016] Improving dm-crypt performance for XTS-AES mode – Levent Demir
Using dedicated hardware is common to accelerate crypto- graphic operations: complex operations are managed by a dedicated co- processor, and data is transferred between RAM and the crypto-engine through DMA operations. The CPU is therefore free for other tasks, which is vital in embedded environments with limited CPU power. In this work we discuss and benchmark XTS-EAS, using either software or mixed approaches, using Linux and dm-crypt, and a low power AT- MEL board, featuring an AES crypto-engine that supports ECB-AES but not the XTS-AES mode. We show that the dm-crypt module used in Linux for full disk encryption has limitations that can be relaxed when considering higher block sizes. We demonstrate that performance gains almost by a factor two are possible, which opens new opportunities for future use-cases.

Domain Name Owners SSL Certificate Problem DEFCON 26
Lost and Found Certificates: dealing with residual certificates for pre-owned domains By Ian Foster, Hacker & Dylan Ayrey, Hacker Summary of Presentation: When purchasing a new domain name you would expect that you are the only one who can obtain a valid SSL certificate for it, however that is not always the case. When the domain had a prior owner(s), even several years prior, they may still possess a valid SSL certificate for it and there is very little you can do about it. Using Certificate Transparency, we examined millions of domains and certificates and found thousands of examples where the previous owner for a domain still possessed a valid SSL certificate for the domain long after it changed ownership. We will review the results from our ongoing large scale quantitative analysis over past and current domains and certificates. We'll explore the massive scale of the problem, what we can do about it, how you can protect yourself, and a proposed process change to make this less of a problem going forwards. We end by introducing BygoneSSL, a new tool and dashboard that shows an up to date view of affected domains and certificates using publicly available DNS data and Certificate Transparency logs. BygoneSSL will demonstrate how widespread the issue is, let domain owners determine if they could be affected, and can be used to track the number of affected domains over time. Speaker Background: Ian Foster Ian enjoys researching systems and networking problems and solutions in an effort to make the world more secure. He has published research papers analyzing the new gTLD land rush and crawling and parsing most WHOIS records. From demonstrating how insecure aftermarket OBD "dongles" can be used to compromise and take over automobiles; to measuring the paths an email traverses online with encryption in an effort to increase integrity, authenticity, and confidentiality; and more. During the day Ian is a Security Engineer fighting for the users. Dylan Ayrey Dylan is a security engineer, who in his free time authors lots of open source projects, such as truffleHog. He graduated college in 2015 and has been working in security ever since.

YVR18-421: Enabling a secure data center with Arm64 architecture
Secure boot helps to plug security vulnerabilities for servers in the data center. The primary requirement to implement secure boot using UEFI is the support for secure storage on the server platform. Existing support for secure storage in implementations of UEFI such as EDK2 are x86 specific relying on the x86 SMM operating mode to provide a hardware enforced sandbox execution environment. AArch64 based platforms rely on S-EL0/1 to provide such a sandbox execution environment to implement secure storage but the upstream EDK2 support for secure storage requires design changes to extend it for AArch64 platforms. This proposal presents those design changes with detailed information of the proposed changes.

The Certified Penetration Testing Consultant course is our advanced course in our penetration testing track. The C)PTC is designed for cyber security professionals and IT network administrators who are interested in conducting Penetration tests against large network infrastructures, such as large corporate networks. The training starts with capturing and analyzing basic packets and continues with Layer2 attack vectors; Layer3 based attacks, including both IPv4 and IPv6 stacks, routing protocol attacks (OSPF, BGP, etc); Service Provider level attacks related with very common used MPLS; how to use relays and pivots; VPN attacks including IPSEC protocol suite; SSL attacks; and finally covers NIDS/NIPS evasion and implementation techniques. At the completion of each module, students are going to be able to practice their knowledge with the lab exercises that are specifically prepared for the covered materials during the theory. Upon Completion Students will: Have the ability to plan, manage, and execute a penetration test. Have knowledge to properly report on a penetration test results. Be ready to sit for the C)PTC Exam Course Content With 8 Modules and 8 appendices, the C)PTC will bring your penetration testing skillset to the next level and prepare you to consult organizations on sucrity issues. Click on a module to view its content. We keep the content of the C)PTC labs protected. There is one lab per module covered. 1: Working with Captured Files 2: Layer 2 Attacks 3: Attacking Routing Protocols 4: Using Pivot Machines 5: IPv6 Attacks 6: VPN attack 7: Defeating SSL, Decrypting Traffic and man-in-the-middle attacks 8: NIDS/NIPS Class Format Options Mile2 offers courses around the year and around the globe. You can attend this course in 2 ways: Instructor-led Classroom: Attend in person. Live-virtual Training: Attend the Instructor-led class remotely. Who Should Attend The Certified Penetration Testing Consultant course is the most advnaced training in mile2’s line of penetration testing courses and certifications. The course prepares students to consult organizations of any size on security by performing penetration test. We assume that people taking this course understand penetration testing and are looking to enhance their skills to the next level. We strongly encourage passing the C)PTE: Certified Penetration Testing Engineer Exam before taking this course or having the equivalent industry experience. Exam Information The Certified Penetration Testing Consultant exam is a 6 hour practical in which you will be conducting both a Vulnerability Assessment and a Full Penetration Test on two IP's. You will then be given 60 days to turn in a written Penetration Test report that will be analyzed by our team of experts. You are required to find at least 80% of the vulnerabilities and then manually test to see if they are legitimate. The report will need to be professionally written, grammatically correct and accurate. This exam is a Pass or Fail. The C)PTC exam is taken online through Mile2’s Assessment and Certification System (“MACS”), which is accessible on your mile2.com account.

btc.edu part 2: Application of Crypto Primitives On How Bitcoin is Built
Slides are here: http://goo.gl/qcliQ0 This developer centered course will be a deep exploration of the evolution of the cryptographic primitives underlying the bitcoin protocol. Symmetric and public-key ciphers, as well as elliptic curve signatures and cryptographic hash functions will be covered, as well as how it all ties together to form the basis of bitcoin. This is part 1 of a larger series of lectures for developers and researchers who want a thorough understanding of how bitcoin functions, and its potentials and risks. Part 2 will extend these cryptographic fundamentals to the specific implementation bitcoin uses, as well as a survey of other cryptographic primitives and mechanisms used in other currencies. The material in the cryptography I course on Coursera (https://www.coursera.org/course/cryptography) may be helpful to those who have less background in cryptography.
