(Nanowerk Spotlight) Hydrogels are crosslinked polymer networks that can absorb huge volumes of water. In recent years, significant progress has been made with so-called "stimuli-responsive" hydrogels ...

AES-256 remains the gold standard for high-stakes data encryption. While other, more lightweight and less-energy-intensive encryption methods do exist, they operate with multiple trade-offs in ...

Whether written invisibly with lemon juice or encrypted with complex math, secret messages are passed on through a myriad of bizarre and convoluted ways. A team of engineers from China is introducing ...

Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols ...

Most industry analyst firms conclude that between 80-90 percent of network traffic is encrypted today. Jeff Costlow, CISO at ExtraHop, explains why this might not be a good thing. Strong encryption is ...

Disk encryption is absolute magic to most non-mathematicians. And like any complex technology, it leads to uncomfortable questions. Does encrypting a disk make it less likely that data can be ...

Today's extremely large and complex ASIC and FPGA designs use significant amounts of third-party intellectual property (IP). These IP blocks may represent general-purpose processor cores, digital ...
