The two providers want to lay the crumbling POTS to rest and replace it with Internet Protocol-based systems that use the same wired and wireless broadband networks that bring Web access, cable programming and, yes, even your telephone service, into your homes. You may think you have a traditional landline because your home phone plugs into a jack, but if you have bundled your phone with Internet and cable services, you're making calls over an IP network, not twisted copper wires. California, Florida, Texas, Georgia, North Carolina, Wisconsin and Ohio are among states that agree telecom resources would be better redirected into modern telephone technologies and innovations, and will kill copper-based technologies in the next three years or so. Kentucky and Colorado are weighing similar laws, which force people to go wireless whether they want to or not. In Mantoloking, N.J., Verizon wants to replace the landline system, which Hurricane Sandy wiped out, with its wireless Voice Link. That would make it the first entire town to go landline-less, a move that isn't sitting well with all residents.

New Jersey's legislature, worried about losing data applications such as credit-card processing and alarm systems that wireless systems can't handle, wants a one-year moratorium to block that switch. It will vote on the measure this month. (Verizon tried a similar change in Fire Island, N.Y., when its copper lines were destroyed, but public opposition persuaded Verizon to install fiber-optic cable.) It's no surprise that landlines are unfashionable, considering many of us already have or are preparing to ditch them. More than 38% of adults and 45.5% of children live in households without a landline telephone, says the Centers for Disease Control and Prevention. That means two in every five U.S. homes, or 39%, are wireless, up from 26.6% three years ago. Moreover, a scant 8.5% of households relied only on a landline, while 2% were phoneless in 2013. Metropolitan residents have few worries about the end of landlines. High-speed wire and wireless services are abundant and work well, despite occasional dropped calls. Those living in rural areas, where cell towers are few and 4G capability limited, face different issues.

The movement to encrypt the web has reached a milestone. As of earlier this month, approximately half of Internet traffic is now protected by HTTPS. In other words, we are halfway to a web safer from the eavesdropping, content hijacking, cookie stealing, and censorship that HTTPS can protect against. Mozilla recently reported that the average volume of encrypted web traffic on Firefox now surpasses the average unencrypted volume

Google Chrome’s figures on HTTPS usage are consistent with that finding, showing that over 50% of of all pages loaded are protected by HTTPS across different operating systems.

This milestone is a combination of HTTPS implementation victories: from tech giants and large content providers, from small websites, and from users themselves.

“A program obfuscator would be a powerful tool for finding plausible constructions for just about any cryptographic task you could conceive of,” said Yuval Ishai, of the Technion in Haifa, Israel. Precisely because of obfuscation’s power, many computer scientists, including Sahai and his colleagues, thought it was impossible. “We were convinced it was too powerful to exist,” he said. Their earliest research findings seemed to confirm this, showing that the most natural form of obfuscation is indeed impossible to achieve for all programs. Then, on July 20, 2013, Sahai and five co-authors posted a paper on the Cryptology ePrint Archive demonstrating a candidate protocol for a kind of obfuscation known as “indistinguishability obfuscation.” Two days later, Sahai and one of his co-authors, Brent Waters, of the University of Texas, Austin, posted a second paper that suggested, together with the first paper, that this somewhat arcane form of obfuscation may possess much of the power cryptographers have dreamed of. “This is the first serious positive result” when it comes to trying to find a universal obfuscator, said Boaz Barak, of Microsoft Research in Cambridge, Mass. “The cryptography community is very excited.” In the six months since the original paper was posted, more papers have appeared on the ePrint archive with “obfuscation” in the title than in the previous 17 years.
