Mobile payment “GB” is still a mystery operators worried about being marginalized

In Jingdong Mall online payment page, PayPal logo has disappeared, people do not terminate suspected of cooperation by both sides. Yesterday, reporters found in Jingdong Mall online payment, represents the bulk of Alipay has disappear from the page, leaving only the caifutong, fast money, 5 kinds of payment methods such as mobile phone payment. Careful users also found that, on April 30, Jingdong Mall has published the bulletin, called Alipay system needs urgent maintenance.

This notice was subsequently removed, but a few days after, Alipay payment from Beijing on the East site “disappear”.

Since then, rumours of outgoing terminate cooperation of both parties. Yesterday, Jingdong Mall customer service said previously is because PayPal is the debug port, is temporarily unavailable, has restored these two days. According to customer’s instructions, reporters choose online payment payment page options have yet to see PayPal at this time, only when the payment order was submitted only in the pages of a modest “view other payment platform” was found in the option to pay Bao.

Beijing Orient home e-commerce company’s General Manager Zhuang Shuai commented on this, Jingdong Mall use Alipay, formalities and not only a separate par with banks, also should always worry about their transactions and user data was competitor research. Jingdong Mall “on ice” Act, is not so much worried about PayPal, Taobao prevention than.

Thanks North Division is a great place for posting
Associate Professor, Department of Beijing Normal University Physics Xiaowen Li collaboration with colleagues at the University of Maryland, recently in the design of physical random number generators have made breakthrough progress. They designed a multichannel, independently of each other, high-speed physical random number generator, the use of ultra broadband optical noise of amplified spontaneous emission of led, through two non-overlapping the optical transmittance filters separate the two signals, each channel bit rate of up to 10G/s. Use this method at the same time produce more than one bit of random bits in parallel, greatly improved the rate of random number generators and upgrade capabilities.

Previously, people had made algebra (software) and based on cellular automata (hardware) parallel pseudo random number generator. Xiaowen Li proved for the first time, from a single optical noise sources, does not need an external optical amplification, and gain, you can also get multiple independent of the bit stream. To date, this is the first parallel output of physical random number system, to fast parallel physical random number generator based on chip has taken an important step. In addition, by using more filters, parallel output can reach at least 20 the number of channels, bit rate can reach new Trojan 200G/s.

Random number generators in the field of business and science have a wide range of applications, including secure key generation, communications, game theory and Monte Carlo calculations. High performance parallel computing demands made using parallel random number, commercialization of the program using a photoelectric device, it is easy to integrate into chip, high performance random number generator as a computer application.
