20130044876 | GENOMICS-BASED KEYED HASH MESSAGE AUTHENTICATION CODE PROTOCOL - Apparatuses, systems, computer programs and methods for implementing a genomics-based security solution are discussed herein. The genomics-based security solution may include reading and parsing a plaintext message comprising a string of words and assigning a lexicographic value to each word in the string to code each word in a rational number. The solution may also include assigning a letter code to each letter. The letter code for each letter may correspond with a function in molecular biology. | 2013-02-21 |
20130044877 | LONG RANGE WLAN DATA UNIT FORMAT - In a method for generating a data unit for transmission in a wireless network, a physical layer (PHY) preamble is generated. In generating the PHY preamble, a first indicator is generated to indicate at least one of (i) whether the data unit includes data offloaded from a mobile telephony network separate from the wireless network, or (ii) whether the data unit (a) was generated by, or (b) is addressed to, a communication device that supports offloading of data from the mobile telephony network to the wireless network. The first indicator is included in the PHY preamble. Additionally, a media access control layer (MAC) header is generated. The data unit is generated to include the PHY preamble and the MAC header. The data unit is then caused to be transmitted. | 2013-02-21 |
