Zimmerman and friends: ´Are you listening? PGP is not broken´

Security News - 12 min 42 sek zpět
EFAIL furore not over yet, even though it´s easy to fix.

However, PGP´s creator Phil Zimmerman, Protonmail´s Any Yenn, Enigmail´s Patrick Brunschwig, and Mailvelope´s Thomas Oberndörfer are still concerned that misinformation about the bug remains in the wild.

Yenn tried to refute the EFAIL “don´t use PGP” on May 25, and the four have followed up with this joint post.

Wah, encryption makes policing hard, cries UK´s National Crime Agency

Security News - 12 min 42 sek zpět
Encryption is making it more difficult for law enforcement agencies to detect dangerous offenders, according the the National Crime Agency's (NCA) yearly assessment of serious organised crime in Britain.

Since 2010, communication service providers have migrated to encrypted services ´by default´, a process that accelerated following the Snowden disclosures, said the National Strategic Assessment of Serious and Organised Crime 2018

NIST starts down road toward IoT encryption

Security News - 12 min 42 sek zpět
The National Institute of Standards and Technology wants comments on the best way to design criteria to evaluate new encryption standards for small computing devices.

NIST will eventually ask researchers and cryptographers for algorithms that could be used to encrypt data on small, "constrained devices," such as sensors, RFID tags, industrial controllers and smart cards that are being incorporated into automobiles, internet-of-things devices, the smart grid and distributed control systems.

But first the agency needs to establish the requirements and evaluation criteria that will guide the review of the algorithms.

Protect sensitive data with these five free encryption apps

Security News - 12 min 42 sek zpět
Mark Kaelin: Protecting customers´ personal data is vitally important to the future success of every organization. Encrypting that data with one of these apps is a good place to start.
Numerous high-profile events in 2017 and early 2018 have made it abundantly clear that all enterprises and government agencies are responsible and liable for the protection of personal data collected from customers and clients—no exceptions. New regulations, such as the GDPR, which goes into effect May 25, 2018, will back those expectations of protection with substantial penalties and fines for the noncompliance.
To avoid potential fines, organizations need to demonstrate initiative by establishing measurable security protocols that protect collected personal data. One of most common methods for protecting stored data is encryption.

A deep dive into blockchain and Bitcoin

Security News - 12 min 42 sek zpět
In (In)secure Magazine Issue 27, March 2018.

Blockchain technology promises to solve many complex problems across different business sectors and industries, and Bitcoin is breaking value records seemingly every hour. But many don’t understand how the two really work, and use the two words interchangeably as if they were synonymous.
One important thing to remember is that blockchain can exist without Bitcoin, but Bitcoin cannot exist without a blockchain.
Bitcoin is a digital currency that was created in 2009. Only 21 million Bitcoins can ever be created (mined), and it is estimated that the last coin will be produced in 2140.
It is exchanged on a decentralized, peer-to-peer network, meaning that there is no central server or authority (i.e., a central bank) that regulates it. In the beginning, the Bitcoin network was operated by volunteers who had a full Bitcoin protocol stack installed on their private computers. However, the network’s operation has mostly been taken over by specialized data centers.
Bitcoin operates on a cryptographic protocol, is fully transparent and open source. As it’s not backed by a real authority, the health of the system depends entirely on the trust people have in it. The value of Bitcoin is determined by the amount people are willing to pay for it.

Google expands work in quantum computing with 72-qubit Bristlecone processor

Security News - 12 min 42 sek zpět
Google has announced the release of the 72-qubit square array Bristlecone quantum processor, which the company believes is adequate to demonstrate quantum supremacy.

Bristlecone is the evolution of Google´s prior 9-qubit linear quantum processor, which had error rates of 1% for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates.

Crypto-gurus: Which idiots told the FBI that Feds-only backdoors in encryption are possible?

Security News - 12 min 42 sek zpět
Four cryptography experts have backed a US Senator´s campaign to force the FBI to explain how exactly a Feds-only backdoor can be added to strong and secure encryption.

The four are: Stanford professor Martin Hellman, of Diffie-Hellman fame and who helped invent the foundations of today´s crypto systems; Columbia professor and USENET co-creator Steve Bellovin; top cryptographer Paul Kocher; and information security guru Bruce Schneier.

All four this week signed a letter (link in article) to Senator Ron Wyden (D-OR) applauding his "effort to find out with whom the bureau has been consulting and which cryptographic experts believe an exceptional access system can be built securely."

18 Cryptography Attacks to Watch Out For

Security News - 12 min 42 sek zpět
Cryptanalysis is the study of ciphertext, ciphers and cryptosystems with the aim of understanding how they work and finding and improving techniques for defeating or weakening them. For example, cryptanalysts seek to decrypt ciphertexts without knowledge of the plaintext source, encryption key or the algorithm used to encrypt it; cryptanalysts also target secure hashing, digital signatures and other cryptographic algorithms.

Did Codebreakers Crack This Mysterious Medieval Manuscript?

Security News - 27 Květen, 2018 - 10:00
The 600-year-old Voynich Manuscript is one of the biggest mysteries in cryptology. Scientists are using AI to try to read it.

A pair of Canadian codebreakers may have deciphered a 600-year-old book that has been baffling cryptologists for centuries. But, more likely, they probably haven't.

In a study published in the journal Transactions of the Association of Computational Linguistics, computing scientists from the University of Alberta used an algorithm to try to decode parts of the Voynich Manuscript, a medieval book written in an undecipherable code with an unknown language.

But other scholars are skeptical, and the manuscript remains a document very much shrouded in mystery.

The Ransomware Survival Handbook

Security News - 25 Květen, 2018 - 10:00
When a ransomware infection spreads through your network, its goal is to encrypt any files it can access (even backups) as quickly as possible. That can happen in a matter of minutes or even seconds. And from there, the clock starts ticking. Because everyone is expecting you to get things back up and running.

Read The Ransomware Survival Handbook and learn how to recover quickly and effectively (and not get hit again).
