In an article published today in Wired magazine, it has long been argued that offline trading is safer than online trading when talking about credit card security. Now, the truth has proved that this view is wrong. Online trading is more popular and safer than ever, thanks to advances in digital payment technology, demographic changes, and a growing network security environment. At the same time, offline payments seem to be less secure than ever. Recently, major foreign retailers have erupted in a series of security incidents, suggesting that offline trading is more vulnerable to attack. These trends lead people to consider ...

Efficient multi-keyword lookup scheme in secure cloud storage qian Ye Fengshun Wang Guojun users, after leasing the storage space of a cloud service provider (Cloud service PROVIDER,CSP), typically store files in ciphertext on the CSP in order to protect privacy. This brings a problem to search for key words in ciphertext data. In this scenario, the CSP is considered a potential attacker. A secure and efficient cloud computing scheme is proposed to support multiple keyword lookups. This scheme is based on the binary sort tree structure, under the premise of guaranteeing the security and privacy of the user data, the branch ...

In terms of security challenges, the DNS solution in cloud computing is incomplete and relies heavily on the combination of people, processes, and technologies. Cloud computing has been challenged by the vast majority of businesses that have implemented a full range of outsourcing to these three areas by migrating applications to cloud computing. All the key technologies are in the cloud-computing vendor, and cloud users rely entirely on cloud providers to secure their information and infrastructure. Therefore, cloud computing customers must also consider the lack of physical control, and provide suppliers with DNS management and processing related 、...

Now for 2011 years, our focus has been more on moving things from a corporate position to a cloud floating in the sky. We've seen the zombie network dismantled by the FBI, and we've seen the coming social network. What do all these events have in common? The common point is the need for precise and secure identity management (identity management). According to recent trends, what does it need to look for in their identity software, from their identity vendors? Here are four guesses about new points and future developments in identity management. 1. Body ...
