Ngx_http_upstream_hash_module This module is provided by a third party and is not included in the Nginx source release version. Upstream_hash This module provides a simple upstream load allocation by hashing a configurable variable (for example, a request URI, an incoming HTTP header, or some combination). Examples of usage are as follows: Upstream backend {: server server1;: Server server2;: Hash $req ...

Cloud data integrity verification algorithm based on homomorphic hash function Zhou Rui Wang Cloud storage has become a trend for future storage development, but it also poses new security challenges, such as the possibility that cloud service providers might tamper with data for some reason. To ensure the integrity of cloud data, a cloud data integrity checking algorithm based on homomorphic hash function is proposed. Under the audit of trusted third party, the algorithm verifies the integrity of cloud data by aggregating multiple RSA signatures. In order not to disclose user data information, the same-state linear authentication and random masking technology are adopted to realize privacy protection. The analysis results show that the algorithm can not only ...

July 19, Australia's most famous group buy website catch the day announced that the site was attacked by hackers, some of its users password and credit card data stolen. 　　It is shocking that this hacker attack took place more than three years ago, and catch of the day only now disclosed the incident. A message was sent to a user according to catch of the day, which was discovered shortly after the website was hacked and sent to the Australian Federal Police (Austra).

The blockchain is a big hit at the moment, and the news media has reported a lot, claiming that it will create the future.

Blockchain is a new technology that is gradually emerging with the increasing popularity of digital cryptocurrencies such as Bitcoin.

Cloud storage is a very attractive service for outsourcing day-to-day data management, but once data is lost, all the consequences will be borne by the company that owns the data, not by the hosting service provider.     With this in mind, it is important to understand the reasons for the loss of data, how much responsibility the cloud service provider is responsible for, how to secure the use of cloud storage, and the integrity monitoring methods and standards regardless of whether the data is stored locally or in the cloud. Integrity monitoring is essential to cloud storage services, as well as data integrity ...

In the case of Bitcoin transactions, blockchain trading is not a transaction in the usual sense of hand-delivering, but a transfer. If each transfer needs to construct a transaction data, it would be awkward.

You can implement your own blockchain with less than 200 lines of Go code! Sounds interesting? What better way to learn than to develop a blockchain of your own? Then let's practice together!

With the rapid growth of the amount of storage data, more and more people begin to pay attention to the method of reducing storage data. Data compression, single-instance storage, and duplicate data deletion are frequently used storage data reduction techniques. Duplicate data deletion often refers to the elimination of redundant child files. Unlike compression, duplicate data deletion does not change the data itself, but eliminates the storage capacity that the same data occupies. Data de-duplication has a significant advantage in reducing storage and reducing network bandwidth, and is useful for scalability. As a simple example: in the special for telecommunications operations agreed to the call details to apply ...
