Appl. No.:

10/074114

Inventors:

Christopher F. Bussan - Crystal Lake IL, US
Joseph M. Hansen - Williams Bay WI, US
Charles P. Binzel - Bristol WI, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B001/16

US Classification:

4553434, 455574, 4553431, 4553432, 455572, 455573, 4551271, 4551275, 713320, 713500, 713600

Abstract:

A method of coordinating events in a microprocessor-based electronic device having a sleep mode to reduce current drain includes a first step of determining a list of times to perform associated operating system events requiring a wake-up period for the device. A next step includes establishing a timing of fixed events wherein the electronic device enters a wake-up period to perform the fixed events. A next step includes delaying the time for an operating system event to coincide with a fixed event such that the electronic device utilizes one coincident wake-up period to perform both of the operating system event and the fixed event. This removes the current drain associated with entering and exited an additional sleep period.

Appl. No.:

11/617003

Inventors:

Kent D. Rager - Gurnee IL, US
Joseph M. Hansen - Williams Bay WI, US

Assignee:

Motorola Mobility, Inc. - Libertyville IL

International Classification:

G06F 9/32

US Classification:

713168, 713170, 713150

Abstract:

An apparatus () used by a plurality of devices to authenticate an accessory () is configured to operate with a device () of the plurality of devices. The accessory () applies an authentication algorithm to a key and a challenge () received from the device () and generates a response () thereto. A challenge and response memory () stores a subset of a set of challenges () and pre-computed responses (). The enabling circuit transmits a challenge () to the accessory () and receives a received response () therefrom. The enabling circuit () also compares the received response () to the stored response () corresponding to the stored challenge () sent to the accessory (). The enabling circuit () is configured to generate a normal operation enabling signal that enables normal operation of the device when the received response () matches the stored response and is configured not to generate the normal operation enabling signal when the received response () does not match the stored response.

Abstract:

A server, e. g. , a client (), receives a request for a digital signature to be applied to digital information, obtains a representation of the information, determines a designation of key pair(s) to be applied thereto; and transmits a request for the digital signature to a front end server (). The front end server determines one or more of whether the client is authentic and authorized, the user identifier is authentic, and the user identifier is permitted to make the request. If so, the front end server transmits a request to generate a digital signature to a back end server (). The back end server determines one or more of whether the front end server is authentic and the designated key pair correspond to the requesting front end server. If so, the back end server generates the digital signature based on the information and the key pair(s).

Abstract:

Techniques are provided for preventing replacement of a one-time-programmable (OTP) component. The OTP component can be part of a wireless device. The wireless device is configured such that programming of a new IMEI code into the OTP component is permitted only when the wireless device is in a secure-mode state. A challenge-response protocol is used to place the wireless device in this secure-mode state.
