LOGGING ENCRYPTED DATA COMMUNICATIONS FOR QOE ANALYSIS

摘要

A device such as a smartphone may communicate with a server or other network entity using encrypted communications, making it difficult to examine such communications for purposes of identifying communication issues that may affect user QoE (quality of experience). In certain embodiments, an application may be modified to log communication data before encryption and after decryption. For example, the application program may be decompiled and logging instructions may be inserted before portion that result in data encryption and after portions where received data is decrypted. The modified application program may then be recompiled and executed on a device to produce an unencrypted log of data. In other embodiments, elements of the device operating system may be modified to log data before encryption and after decryption.

主权项

1. A method for evaluating a quality of experience provided by an application program that runs on a device and that communicates with a server using an encrypted communication protocol, the method comprising:
decompiling the application program; identifying a first portion of the application program that receives outbound data prior to encryption of the outbound data; modifying the first portion of the application program to create a modified application program, wherein the modifying comprises configuring the application program to log the outbound data prior to the encryption of the outbound data; compiling the modified application program; and installing the modified application program on the device.
