Forbes: Are Blockchains Vulnerable, Slow and Unfair?

Cryptocurrency and non-fungible tokens (NFTs) have grown in popularity in 2021. Bitcoin, the leading cryptocurrency, has soared again in value and picked up mainstream institutional support, even amidst continued volatility. NFTs have become hot collector’s items.

The rising acceptance of cryptocurrency and NFTs makes this a good time to examine the blockchain technologies they rely on. The recent Financial Cryptography and Data Security 2021 conference (FC21), which I mentioned in a previous article, is a good place to start. On the agenda were discussions of cryptocurrency mining attacks, poor blockchain performance and a lack of fairness in blockchain applications. Computer scientists have concerns with both blockchain’s fundamentals and its applications…

AiThority: NTT Research Names Iris Shelly MEI Lab Scientist

NTT Research, Inc., a division of NTT, announced that it has named Iris Shelly as a Scientist in its Medical & Health Informatics (MEI) Lab. Shelly, an applied research engineer with expertise in biomedical signal processing and low-power devices, joined NTT Research in June 2021. She was most recently a Senior Applied Research Engineer at BIOTRONIK/Micro Systems Engineering, Inc. where she designed, developed and validated cardiac arrhythmia detection algorithms. Shelly brings this experience to the MEI Lab where she will initially work on model architecture and the interface for the bio digital twin initiative. Following Shelly’s initial research priorities, she will work on several other aspects of the bio digital twin initiative, including disease-related aspects of the model…

CSO Online: New US CISO appointments, May 2021

The upper ranks of corporate security are seeing a high rate of change as companies try to adapt to the evolving threat landscape. Many companies are hiring a chief security officer (CSO) or chief information security officer (CISO) for the first time to support a deeper commitment to information security.

Follow this column to keep up with new appointments to senior-level security roles and perhaps gain a little insight into hiring trends…

CNET: Quantum computers could crack today’s encrypted messages. That’s a problem

Quantum computers, if they mature enough, will be able to crack much of today’s encryption. That’ll lay bare private communications, company data and military secrets. Today’s quantum computers are too rudimentary to do so. But data surreptitiously gathered now could still be sensitive when more powerful quantum computers come online in a few years. The computing industry is well aware of this potential vulnerability. Some companies have embarked on an effort to create, test and adopt new encryption algorithms impervious to quantum computers…

The Last Watchdog: MY TAKE – Agile cryptography is coming, now that ‘attribute-based encryption’ is ready for prime time

Encryption agility is going to be essential as we move forward with digital transformation.

All of the technical innovation cybersecurity vendors are churning out to deal with ever-expanding cyber risks, at the end of the day, come down to protecting encrypted data. But cryptography historically has been anything but agile; major advances require years, if not decades, of inspired theoretical research.

Now comes something called attribute-based encryption, or ABE, a new approach to encrypting data that holds the potential to infuse agility into how encryption gets done online…

AiThority: NTT Research and Tokyo Institute of Technology Target Two Applications for CIM

NTT Research, Inc., a division of NTT, announced that it has entered into a joint research agreement with Tokyo Institute of Technology (Tokyo Tech) to develop applications for the Coherent Ising Machine (CIM). The two targeted applications for the CIM, an information processing platform based on quantum oscillator networks, are compressed sensing and drug discovery, both of which require extremely high levels of processing on existing computers. Two agreements, signed in 2020, call for collaboration between NTT Research’s Physics & Informatics (PHI) Lab and independent research groups in Tokyo Tech’s School of Computing, directed by Drs. Yukata Akiyama and Toru Aonishi…

The Last Watchdog: MY TAKE—Why monetizing data lakes will require applying ‘attribute-based’ access rules to encryption

We’ve barely scratched the surface of applying artificial intelligence and advanced data analytics to the raw data collecting in these gargantuan cloud-storage structures erected by Amazon, Microsoft and Google. But it’s coming, in the form of driverless cars, climate-restoring infrastructure and next-gen healthcare technology.

In order to get there, one big technical hurdle must be surmounted. A new form of agile cryptography must get established in order to robustly preserve privacy and security as all this raw data gets put to commercial use.

I recently had the chance to discuss this with Kei Karasawa, vice president of strategy, and Fang Wu, consultant, at NTT Research, a Silicon Valley-based think tank which is in the thick of deriving the math formulas that will get us there…
