Will The TeraHertz Band Increase Wi-Fi Speeds?

Comments Off on Will The TeraHertz Band Increase Wi-Fi Speeds?

Researchers have worked out a way to push Wi-Fi speeds to 34 Gbps using the TeraHertz band.

While greater bandwidth in the 300GHz and above band has been known for a while it is pointless because the range makes it a chocolate teapot.

Some researchers have managed to hit 100 Gbps but when it only works for a few centimeters it is not commercially viable.

Now boffins at the Tokyo Institute of Technology have got the technology to provide a great 34 Gbps speed with a decent range.

Naoto Oshimo, one of the scientists behind this latest test, said that “device performance is almost sufficient for short-distance wireless communication such as KIOSK downloads, which might be its first application”. By that they mean that they have managed 10 metres, almost OK for home use.

Oshimo believes that this technology will scale hugely in terms of the speed as well, and we could eventually be looking at topping the 1Tbps mark.

CVS Debuts CVS Pay

Comments Off on CVS Debuts CVS Pay

CVS has rolled out its CVS Pay program that exists inside its mobile app. It allows customers to pay in store for prescriptions by scanning a barcode at the register.

Payments will be backed by a customer’s credit or debit card, the company said.

CVS Pay is currently available in New York, New Jersey, Pennsylvania and Delaware; a nationwide rollout at all 9,600 stores is expected to kick off later this year.

CVS doesn’t support Apple Pay or other NFC-based payment technologies, and its use of barcodes for payments is reminiscent of the way Starbucks customers pay for coffee. Working with the barcode technology was a faster way for CVS to bring forward technology for more convenient in-store payments, analysts said.

Other retailers have created in-store payments through their own apps. Walmart created Walmart Pay in December to allow payments through mobile device QR codes that can be read at checkout registers.

“There’s nothing really innovative here with CVS Pay,” said Gartner analyst Avivah Litan on Friday. “They are pretty much following the trend. It’s just mobile commerce with a credit card attached. It’s no big deal to put a credit card in a wallet.”

At one point, CVS was working with Walmart and dozens of other major retailers in the Merchant Customer Exchange, which was designed to process mobile payments electronically through bank accounts and not credit cards to cut out the card processing cost that merchants paid to banks. But MCX ended its pilot of its mobile app, CurrentC, in June. Analysts have predicted the concept will not continue.

Apple Changes Policy In China

Comments Off on Apple Changes Policy In China

Apple Inc has started the processing of keeping the personal data of some Chinese users on servers in mainland China, marking the first time the tech giant is storing user data on Chinese soil.

The storage of user data in China represents a departure from the policies of some technology companies, notably Google Inc, which has long refused to build data centers in China due to censorship and privacy concerns.

Apple said the move was part of an effort to improve the speed and reliability of its iCloud service, which lets users store pictures, e-mail and other data. Positioning data centers as close to customers as possible means faster service.

The data will be kept on servers provided by China Telecom Corp Ltd, the country’s third-largest wireless carrier, Apple said in a statement.

“Apple takes user security and privacy very seriously,” it said. “We have added China Telecom to our list of data center providers to increase bandwidth and improve performance for our customers in mainland china. All data stored with our providers is encrypted. China Telecom does not have access to the content.”

A source with knowledge of the situation said the encryption keys for Apple’s data on China Telecom servers would be stored offshore and not made available to China Telecom.

Apple has said it has devised encryption systems for services such as iMessage that even Apple itself cannot unlock. But some experts expressed scepticism that Apple would be able to withhold user data in the event of a government request.

“If they’re making out that the data is protected and secure that’s a little disingenuous because if they want to operate a business here, that’d have to comply with demands from the authorities,” said Jeremy Goldkorn, director of Danwei.com, a research firm focused on Chinese media, internet and consumers.

“On the other hand if they don’t store Chinese user data on a Chinese server they’re basically risking a crackdown from the authorities.”

Goldkorn added that data stored in the United States is subject to similar U.S. regulations where the government can use court orders to demand private data.

A spokesman for China Telecom declined to comment.

Twitter’s Authentication Has Vulnerabilities

Comments Off on Twitter’s Authentication Has Vulnerabilities

Twitter’s SMS-based, two-factor authentication feature could be abused to lock users who have not enabled it for their accounts if attackers gain access to their log-in credentials, according to researchers from Finnish antivirus vendor F-Secure.

Twitter introduced two-factor authentication last week as an optional security feature in order to make it harder for attackers to hijack users’ accounts even if they manage to steal their usernames and passwords. If enabled, the feature introduces a second authentication factor in the form of secret codes sent via SMS.

According to Sean Sullivan, a security advisor at F-Secure, attackers could actually abuse this feature in order to prolong their unauthorized access to those accounts that don’t have two-factor authentication enabled. The researcher first described the issue Friday in a blog post.

An attacker who steals someone’s log-in credentials, via phishing or some other method, could associate a prepaid phone number with that person’s account and then turn on two-factor authentication, Sullivan said Monday. If that happens, the real owner won’t be able to recover the account by simply performing a password reset, and will have to contact Twitter support, he said.

This is possible because Twitter doesn’t use any additional method to verify that whoever has access to an account via Twitter’s website is also authorized to enable two-factor authentication.

When the two-factor authentication option called “Account Security” is first enabled on the account settings page, the site asks users if they successfully received a test message sent to their phone. Users can simply click “yes,” even if they didn’t receive the message, Sullivan said.

Instead, Twitter should send a confirmation link to the email address associated with the account for the account owner to click in order to confirm that two-factor authentication should be enabled, Sullivan said.

As it is, the researcher is concerned that this feature could be abused by determined attackers like the Syrian Electronic Army, a hacker group that recently hijacked the Twitter accounts of several news organizations, in order to prolong their unauthorized access to compromised accounts.

Some security researchers already expressed their belief that Twitter’s two-factor authentication feature in its current implementation is impractical for news organizations and companies with geographically dispersed social media teams, where different employees have access to the same Twitter account and cannot share a single phone number for authentication.

Twitter did not immediately respond to a request for comment regarding the issue described by Sullivan.

Hackers Attempt To Access AT&T Mobile

Comments Off on Hackers Attempt To Access AT&T Mobile

AT&T Inc, the No. 2 U.S. wireless carrier, said it is investigating an “organized and systemic attempt” to access mobile customers’ information but that it did not believe any accounts were breached.

The company, which had 100 million subscribers at the end of the third quarter, said it is advising less than 1 percent of its wireless customers that there was an attempt to obtain information about their accounts.

It said that the parties involved appeared to have used “auto script” technology to see if AT&T telephone numbers were linked to online AT&T accounts.

Spokesman Mark Siegel said AT&T’s “investigation is ongoing to determine the source or intent of the attempt to gather this information.”
