+ * \ingroup wrappers
+ *
+ * This wrapper aims on prevention of microarchitectural attacks. This
+ * code was originally a part of [ChromeZero](https://github.com/IAIK/ChromeZero).
+ *
+ * The wrappers support the following behaviour:
+ *
+ * * Polyfill: Completely eliminates the paralelism.
+ * * Randomly slow messages: Add noise to the `postMessage` method execution.
+ *
+ * \see Lipp, M., Gruss, D., Schwarz, M., Bidner, D., Maurice, C. et al. Practical
+Keystroke Timing Attacks in Sandboxed JavaScript. In:. August 2017, s. 191–209.
+ISBN 978-3-319-66398-2.
