  1. The new IBM Power10 chip will be manufactured by Samsung and based on its new seven-nanometer process. It features 18 billion transistors, 30 cores, a Matrix Math Accelerator to speed up artificial intelligence performance, and multiple AES engines for performing data encryption. The Power10 chip has four times as many AES engines as the Power9. https://newsroom.ibm.com/2020-08-17-IBM-Reveals-Next-Generation-IBM-POWER10-Processor
  2. Zoom has acquired Keybase, the people behind Saltpack https://saltpack.org/ The acquisition is expected to help deliver end-to-end encryption for Zoom. It also made a commitment not to build a backdoor into its security. https://blog.zoom.us/wordpress/2020/05/07/zoom-acquires-keybase-and-announces-goal-of-developing-the-most-broadly-used-enterprise-end-to-end-encryption-offering/ https://keybase.io/blog/keybase-joins-zoom
  3. The Zoom version 5.0 update improves the encryption used to protect call data. Zoom is upgrading from 128-bit Advanced Encryption Standard (AES) keys to AES 256-bit GCM encryption. https://mashable.com/article/zoom-encryption-update/

    hCaptcha

    hCaptcha protects user privacy, rewards websites, and helps companies get their data labelled. It is a drop-in replacement for reCAPTCHA: you can switch within minutes. hCaptcha is free to use for publishers of any size. When you use hCaptcha, companies bid on the work your users do as they prove their humanity. You get the rewards. hCaptcha also offers an option to support the charities of your choice with the earnings you gain from using it. The hCaptcha marketplace is powered by the HUMAN Protocol, an open decentralized protocol for human review that runs on the Ethereum blockchain. We
  5. Google, Microsoft and Mozilla have re-enabled support for Transport Layer Security (TLS) 1.0 and 1.1, because of the COVID-19 pandemic. Browser makers restore support for obsolete TLS 1.0 and 1.1 encryption https://www.computerworld.com/article/3535806/browser-makers-cite-coronavirus-restore-support-for-obsolete-tls-10-and-11-encryption.html
  6. Web servers that haven’t disabled TLS 1.0 and TLS 1.1 will be downgraded in https testing results. Qualys advises: TLS 1.0 and TLS 1.1 protocols will be removed from browsers at the beginning of 2020. As there are no fixes or patches that can adequately fix SSL or deprecated TLS, it is critically important that organizations upgrade to a secure alternative as soon as possible. https://blog.qualys.com/ssllabs/2018/11/19/grade-change-for-tls-1-0-and-tls-1-1-protocols?fbclid=IwAR2VBdySrhbtuz28N6c0wb9c3axB7-6nY4ANHhuB3e7wKelQ9_q_szmr944
  7. Emmanuel Thomé and his colleagues at the National Institute for Research in Computer Science and Automation (Inria) have cracked the largest key so far. The team factored RSA-240, an RSA key with 240 decimal digits. The total computing time took was equivalent to a single computer core running for almost 4000 years. https://www.newscientist.com/article/2226458-number-crunchers-set-new-record-for-cracking-online-encryption-keys/ https://www.popularmechanics.com/science/math/a30149512/longest-encryption-ever-cracked/ https://www.darkreading.com/vulnerabilities---threats/scientists
  8. Mastercard, Visa, eBay and Stripe have also withdrawn from the Libra Association. https://www.bbc.co.uk/news/technology-50023008
  9. The Libra Association co-founded by Facebook aims to serve as a monetary authority for the Libra cryptocurrency. It says Libra's purpose is to "empower billions of people," citing 1.7 billion adults without bank accounts who could use the currency. The Libra Association is a group of 28 companies and non-profits helping to develop Libra. The Libra blockchain is implemented using Rust. The coding guidelines for the Libra Core Rust codebase are at https://developers.libra.org/docs/community/coding-guidelines On Friday 4th October, PayPal announced its withdrawal from the project.

  10. NIST has a section for Threshold Encryption and says it has areas of relevant related research including secure multi-party computation, intrusion tolerant distributed systems, and threshold circuit design... https://csrc.nist.gov/Projects/Threshold-Cryptography
  11. VeraCrypt is now available from https://www.veracrypt.fr/en/Home.html VeraCrypt 1.22 was released in March 2018. It included Kuznyechik speedup, new cascades cipher algorithms, and TRIM support for SSD. VeraCrypt 1.23 was released in September 2018. It added a default SecureBoot for the Windows EFI system.
  12. Tesla has confirmed that it will carry out an over-the-air software update to fix a security flaw in key fobs for the Tesla S. The key fob, manufactured by Pektron, was previously based on 40-bit encryption, and upgraded to 80-bit encryption after it was found that fobs could be easily cloned. Unfortunately the latest fobs have a bug which allows two 40-bit keys to be cracked instead of the expected 80-bit key. Further information about the hack is at https://carbuzz.com/news/turns-out-the-tesla-model-s-is-still-easy-to-hack
  13. There is an interesting discussion of the cryptographic strength of Data's password at https://orbitalflower.github.io/tv/startrek/datas-password.html The password has 52 characters - 173467321476c32789777643t732v73117888732476789764376 You will need to memorise this password if you want to sing along to Data & Picard by Pogo
  14. I have always been interested in Steganography but this process would rely upon the security of the message board, and their network connections. An interesting concept nonetheless.
  15. A couple of thoughts... if you have repeated characters and you can choose different positions then when you re-run the encryption you could reveal which characters are the same. If the plain text is English then we could expect the most duplicated characters to be the letter E, and the least duplicated to be letters such as Q and Z, and then just test out different character mapping arrangements. However I don't fully understand the decryption process... if you give me the key of XYZ and positions 2,1,4,3,5 how do I know which letter a position relates to unless it is in the key. How do

  17. You are very welcome to post here. Forum guidelines are here but basically are just about being polite to one another. For video/files etc I recommend hosting off-site with YouTube/DropBox etc and linking to them so that your copy stays safe. Looking forward to hearing more about your concept.
  18. One area it might be useful is for a blind auction. I think this method would rely upon a per-document key rather than a per-user key, similar to https://github.com/owncloud The process is outlined in more detail here... https://security.stackexchange.com/a/78933 However this only covers multi-user encryption, rather than your lockdown until all users have completed. Perhaps that aspect is better covered by file access after the encrypting stages?

  21. Self-taught Belgian bloke cracks crypto conundrum that was supposed to be uncrackable until 2034 By Katyanna Quach 30 Apr 2019 at 06:04 https://www.theregister.co.uk/2019/04/30/cryptography_conundrum_cracked/ 'It was easy, for some definition of easy,' solver tells El Reg A cryptographic puzzle proposed two decades ago that involves roughly 80 trillion squarings has been cracked much earlier than expected - in just three and a half years. On Monday, the puzzle was solved by Bernard Fabrot, a self-taught independent Java developer from Belgium. The time capsule will, thus, be c
  22. Description of the LCS35 Time Capsule Crypto-Puzzle by Ronald L. Rivest April 4, 1999 As part of the celebration of the 35th birthday of MIT's Laboratory for Computer Science, LCS Director Michael Dertouzos will present an "LCS Time Capsule of Innovations" to architect Frank Gehry. The Time Capsule will reside in the new building, designed by Gehry, that will house LCS. The time capsule will be unsealed on the earlier of 70 years from the inception of the Laboratory (on or about 2033), or upon solution of a cryptographic puzzle, described herein. This puzzle is designed to take approximately 3
  23. The European Commission has issued a product recall for the ENOX Safe-KID-One. The device is a smartwatch designed for children. The EC recall states: the mobile application accompanying the watch has unencrypted communications with its backend server and the server enables unauthenticated access to data. As a consequence, the data such as location history, phone numbers, serial number can easily be retrieved and changed. A malicious user can send commands to any watch making it call another number of his choosing, can communicate with the child wearing the device or locate the child thro
  24. Microsoft has revealed details of an incident where an automated process, designed to trigger when custom keys are removed from KeyVault, caused TDE databases to be dropped from Azure on 29 January 2019. Microsoft tried to restore customer data from a five-minutes-ago snapshot resulting in empty databases and new database names for some. Transactions, product orders, and other updates during that five minute period were lost. Compensation is available to affected customers.
