According to Adobe, "HTML5 is now widely supported by mainstream mobile devices and is the best solution for creating and deploying browser content for mobile platforms ."
For enterprise attackers, this is undoubtedly a bad news. In recent years, Flash has be

3. Data and Code separation principles 4. The principle of unpredictability
Even if code cannot be repaired, it can be considered a successful defense if it can invalidate the method of attack.
The implementation of unpredictability often requires the use of encryption algorithm, random number algorithm, hashing algorithm, good use of this principle, in the design of
