Embodiments are provided for managing user credentials that enable access to secure websites. According to certain aspects, a browser device connects () to a website server that hosts a secure website. The browser device initiates () a credential request and enters () a discovery routine with a mobile device. After establishing () a secure channel with the mobile device, the browser device sends () an identification of the secure website to the mobile device, which identifies () corresponding user credentials and sends () the user credentials to the browser device. The browser device populates () a login page with the user credentials and accesses () the secure website.

Systems and methods for credential management between electronic devices

A multi-media device interface () couples a multi-media device () to a portable electronic device (). Multi-media and other information can be loaded into the portable electronic device () from the multi-media device () or stored in the multi-media device () from the portable electronic device (). The multi-media device interface () queues commands to the multi-media device () from the portable electronic device () while the multi-media device () completes a previously-issued command.

Command queuing for multimedia storage devices

A method, telecommunication apparatus, and electronic device for securely creating an identity data block are disclosed. A secure memorymay store a unique private keyassociated with a unique public key. A processormay generate the identity data blockin the secure memoryusing the unique private key. The processormay erase the unique private keyfrom the secure memory

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).

Distributed digital signature generation

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.

Method to authenticate an accessory

A method and apparatus is provided for power conservation of a hardware module () which is coupleable to a portable electronic device (). The hardware module () has unique identification information associated therewith and stored therein. The unique identification information is provided periodically () to the portable electronic device () and stored therein (). To conserve power, the portable electronic device () sends a power-down notice () to the hardware module (), the module controller () stores current state information of the hardware module () in a non-volatile memory () thereof, and the hardware module () is powered off ().

Method and apparatus for secure module restoration

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.

Event coordination in an electronic device to reduce current drain

A microcontroller (100) with an expansion port (112) includes internal ROM (110) and EEPROM (109) and an external expansion port. The EEPROM internal to the microcontroller is programmable only when the CPU (102) is executing instructions within the internal ROM. Additionally, instructions associated with a secure operation stored in the internal ROM may not be accessed without first executing the beginning instruction of the secure operation. Attempts to begin execution of the secure operation at any point other than the legal entry address will cause the internal ROM (110) to be disabled.
