It’s yet another hardware side-channel attack: The threat resides in the chips’ data memory-dependent prefetcher, a hardware optimization that predicts the memory addresses of data that running code is likely to access in the near future. By loading the contents into the CPU cache before it’s actually …

People ask them about becoming pregnant or terminating or preventing pregnancy, consult them when considering a divorce …
Amazon Web Services (AWS) is excited to announce that AWS Wickr has achieved Federal Risk and Authorization Management Program (FedRAMP) authorization at the High impact level from the FedRAMP Joint Authorization Board (JAB). FedRAMP is a U.S. government–wide program that promotes the adoption of secure cloud services …
Apple announced PQ3, its post-quantum encryption standard based on the Kyber secure key-encapsulation protocol, one of the post-quantum algorithms selected by NIST in 2022. There’s a lot of detail in the Apple blog post, and more in Douglas Stabila’s security analysis. I am of two minds about …
The European Court of Human Rights has ruled that breaking end-to-end encryption by adding backdoors violates human rights : Seemingly most critically, the [Russian] government told the ECHR that any intrusion on private lives resulting from decrypting messages was “necessary” to combat terrorism in a democratic society. To back up …

Susan Landau published an excellent essay on the current justification for the government breaking end-to-end-encryption: child sexual abuse and exploitation (CSAE). She puts the debate into historical context, discusses the problem of CSAE, and explains why breaking encryption isn’t the solution. [...]
Totally expected, but still good to hear : Onstage at TechCrunch Disrupt 2023, Meredith Whittaker, the president of the Signal Foundation, which maintains the nonprofit Signal messaging app, reaffirmed that Signal would leave the U.K. if the country’s recently passed Online Safety Bill forced Signal to build “backdoors …

The cryptocurrency fintech startup Prime Trust lost the encryption key to its hardware wallet—and the recovery key—and therefore $38.9 million. It is now in bankruptcy. I can’t understand why anyone thinks these technologies are a good idea. [...]
I just read an article complaining that NIST is taking too long in finalizing its post-quantum-computing cryptography standards. This process has been going on since 2016, and since that time there has been a huge increase in quantum technology and an equally large increase in quantum understanding and interest …
Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world. The European Telecommunications Standards Institute (ETSI), an organization that standardizes technologies across the industry, first created TETRA in 1995. Since then, TETRA has been used in products …

But now it’s finally getting a public airing thanks …
Enlarge (credit: Bet_Noire/Getty ) From TikTok to Huawei routers to DJI drones, rising tensions between China and the US have made Americans—and the US government—increasingly wary of Chinese-owned technologies. But thanks to the complexity of the hardware supply chain, encryption chips sold by the subsidiary of a …
New research suggests that AIs can produce perfectly secure steganographic images: Abstract: Steganography is the practice of encoding secret information into innocuous content in such a manner that an adversarial third party would not realize that there is hidden meaning. While this problem has classically been studied in security …
AWS is excited to announce a new eBook, 5 Keys to Secure Enterprise Messaging. The new eBook includes best practices for addressing the security and compliance risks associated with messaging apps. An estimated 3.09 billion mobile phone users access messaging apps to communicate, and this figure is projected …
In an open letter, seven secure messaging apps—including Signal and WhatsApp—point out that the UK’s Online Safety Bill could destroy end-to-end encryption: As currently drafted, the Bill could break end-to-end encryption,opening the door to routine, general and indiscriminate surveillance of personal messages of friends, family …
CRYSTALS-Kyber is one of the public-key algorithms currently recommended by NIST as part of its post-quantum cryptography standardization process. Researchers have just published a side-channel attack—using power consumption—against an implementation of the algorithm that was supposed to be resistant against that sort of attack. The algorithm is …
Given the pace of Amazon Web Services (AWS) innovation, it can be challenging to stay up to date on the latest AWS service and feature launches. AWS provides services and tools to help you protect your data, accounts, and workloads from unauthorized access. AWS data protection services provide encryption …
This is a neat piece of historical research. The team of computer scientist George Lasry, pianist Norbert Biermann and astrophysicist Satoshi Tomokiyo—all keen cryptographers—initially thought the batch of encoded documents related to Italy, because that was how they were filed at the Bibliothèque Nationale de France. However …
A group of Swiss researchers have published an impressive security analysis of Threema. We provide an extensive cryptographic analysis of Threema, a Swiss-based encrypted messaging application with more than 10 million users and 7000 corporate customers.
