Android Chrome supports faster secure encryption algorithms

Google has recently accelerated the browsing of Android platform security pages by controlling browsers and the sites it accesses--Elie Bursztein, head of Google's Anti-Abuse research team, said in a Thursday blog post that Google has launched a faster new encryption algorithm These two cryptographic algorithms, named ChaCha20 and Poly1305, are added to the Chrome browser.

"ChaCha20 and Poly1305 will appear very fast on mobile and wearable devices," says Bursztein. Part of the reason is that these algorithms can take advantage of some of the acceleration features in arm chips. And such algorithms can effectively prevent data eavesdropping, including from government monitoring and some malicious hackers to steal passwords and other acts.

Older encryption algorithms need to be replaced gradually, as researchers have discovered the means to crack these algorithms, and the current computing device has an increasingly powerful ability to perform cryptographic cracking. According to Google security experts and programmers Adam Langley, Google is very fond of a new algorithm called AES-GCM, but this algorithm and some have not been applied to the mobile phone's accelerated hardware coordination to show the best results. Based on this, Google uses the CHACHA20 and its associated Poly1305 algorithm.

Bursztein explains that chacha20-poly1305 's fusion algorithm can emit encrypted data at 139.9MBPs (megabytes per second) on smartphones using Xiao S4 Pro chips, such as Nexus Pro chips on Google's S4 4 phone. In contrast, the AES-GCM algorithm encrypts the data at a rate of only 41.5MBps.

Google has been implementing a wider range of cryptographic applications in the Web world for years. Mobile devices are often limited by slower internet connection speeds, as well as the endurance requirements that make it impossible for mobile devices to perform more energy-efficient cryptographic calculations, which are the shackles of Web page encryption. The current chacha20-poly1305 is still a standard yet to be completed, but Langley and other researchers are working to make it the IETF standard, and they expect browsers such as Firefox to adopt such algorithms and to add support for Open-source OpenSSL and NSS software and add support directly to the Android system.

But Google, in fact, already has the biggest chips in the internet world, such as Google search and Gmail, and the popularity of Chrome and Android, the implementation of such cryptographic algorithms may appear more rapid.
