Abstract: A method for generating random numbers includes initializing a pseudo-random number generator (PRNG) having a state of 2048 bits comprising inner bits and outer bits, the inner bits comprising the first 128 bits of the 2048 bits and the outer bits comprising the remaining bits of the 2048 bits. The method also includes retrieving AES round keys from a key source, and for a threshold number of times, executing a round function using the AES round keys by XOR'ing odd-numbered branches of a Feistel network having 16 branches of 128 bits with a function of corresponding even-numbered neighbor branches of the Feistel network, and shuffling each branch of 128 bits into a prescribed order. The method also includes executing an XOR of the inner bits of the permuted state with the inner bits of a previous state.

Abstract: Methods, systems, and media for processing queries relating to presented media content are provided. In some implementations, a method comprises: receiving a request to associate with a media playback device that is presenting media content to a user of the mobile device; activating a microphone associated with the mobile device; converting received ambient sounds to text inputs; determining whether the text inputs include a trigger term and the query; determining media playback information from the media application that includes timing information corresponding to when during the presentation of the media content the query was received and media content identification information; causing a search to be performed that includes the query, the timing information, and the media content identification information; obtaining a search result that is responsive to the query; and presenting the search result on a display associated with the mobile device.
