In order to improve the security of users, Google is constantly working to improve the algorithms of the Android operating system. One of the ways to combat the leak of user data is to encrypt traffic that arrives on or leaves the smartphone. The company announced a new version of the “transport layer” security protocol TLS 1.3 and demonstrated how the security of Android devices has grown compared to last year.
The company Google said that as of the end of 2019, at least 80% of Android applications encrypt all traffic by default. This figure applies to absolutely all smartphones running various versions of the mobile OS. If we take into account only versions of Android 9 and Android 10, then the proportion of applications using encryption will be 90%.
To demonstrate the dynamics of the use of traffic encryption in applications, Google provided a graph. If at the beginning of 2018, applications did not encrypt transmitted text at all when sending and receiving from a smartphone, now only one out of ten applications does not.
Google noted that it added a warning to the Android Studio development environment that reminds the programmer that refusing encryption makes the application less secure. Activation of encryption allows you to make the interception of information sent by hackers useless because it will be impossible to find out about the contents of the information block without a key stored on the smartphone.
