Publication number: 20180091188Abstract: A method for generating spread spectrum spreading sequences in communicating devices. A first device receives a first sequence of one or more radio frequency (RF) signals from a second device, sends a second sequence of one or more RF signals to the second device, samples the first sequence of one or more RF signals, generates sampling results, and generates a spreading sequence based on the sampling results. The second device receives the second sequence and creates an identical spreading sequence using an identical process to create sampling results and generate the sequence. The spreading sequence may be used by the first and second devices for spread spectrum communications with each other. Gain for spread spectrum communications may be dynamically varied based on available bandwidth by varying the number of RF signals and sampling rate.Type: ApplicationFiled: September 23, 2016Publication date: March 29, 2018Applicant: Microsoft Technology Licensing, LLCInventors: Amer Hassan, Edward Giaimo

Publication number: 20180077570Abstract: A forced failure mode may be activated if a predetermined number of incorrect passwords are received at an apparatus. In forced failure mode, the apparatus determines if a forced failure is to be performed in response to a received password. If a forced failure is to be performed, an access failure is forced. When subsequent passwords are received the determine operation is repeated. When it is determined that a forced failure is not to be performed in response to a password entry, access may be granted if the password is correct, or denied if the password is incorrect. The apparatus may then leave forced failure mode or repeat forced failure mode. The apparatus may be configured in a mobile device and the access attempted may be unlocking of the device. The apparatus may also be configured in a network server and the access attempted may be network access.Type: ApplicationFiled: September 14, 2016Publication date: March 15, 2018Applicant: Microsoft Technology Licensing, LLCInventor: Amer Hassan

Publication number: 20180013553Abstract: The embodiments provide a cryptography key for two communicating devices that is based on information known only to the devices. The information may only be determined by the devices. Each device determines the information without communicating key information related to the encryption key with the other. Channel characteristic reciprocity between the devices allows creation of identical keys in each device. Each device sends a signal to the other device at the same power level based on the distance between the devices. The power level may be set to result in a target receive power level at the other device. Each device samples the received signal, generates sampling results, creates a key based on the sampling results and a threshold power level, and utilizes the key. The threshold power level may be based on the target receive power level, or a median power determined from the sampling results.Type: ApplicationFiled: September 23, 2016Publication date: January 11, 2018Applicant: Microsoft Technology Licensing, LLCInventor: Amer Hassan

Publication number: 20180013755Abstract: Embodiments utilize two types of passwords that each, separately, allow a device user to logon to a network. The first is a master password that allows a user to log on at any time. The second is a turn-varying password that changes with each logon and is valid for only one logon. The network may be accessed by using either the master password or the turn-varying password. The turn-varying password may be presented to a user at the device. A device and a network apparatus may each initially synchronize and maintain a turn state that is based on a number of user logons. When a logon occurs, the device and network apparatus update the turn-varying password for the next logon using the turn-varying password. If a user is in an unsecure location and logs on only using the turn-varying password, a sniffed or stolen turn-varying password is not useable.Type: ApplicationFiled: July 8, 2016Publication date: January 11, 2018Applicant: Microsoft Technology Licensing, LLCInventor: Amer Hassan
