    摘要: During generation of a signature on a message to create a signed message, a signer determines one of the signature components such that particular information can be extracted from the signature component. The particular information may be related to one or more of the signer and the message to be signed. After receiving a signed message purported to be signed by the signer, a verifier can extract the particular information from the signature component.

    摘要: A smart card reader receives an Answer to Reset (ATR) from a smart card and transmits the ATR over a communication link to a computing device without waiting for an ATR request from the computing device. The computing device may cache the ATR and use it for subsequent communication sessions with the smart card.

    摘要: Various embodiments are described for providing password approval on a device. The password approval includes getting the user password, generating at least one symbolically equivalent password and then comparing the at least one symbolically equivalent password with at least one specified forbidden password. The user password is disapproved if one of the symbolically equivalent passwords corresponds to the at least one forbidden password.

    摘要: A handheld data processing device includes stored data that is intended to be kept secure from unauthorized access. The handheld data processing device includes applications that store such secure data and which make use of plain text data corresponding to the secure data. An identifier is defined to be associated with defined plain text data. When the handheld data processing device is placed in a locked or secure state, code executable on the device is able to search for plain text identifiers. Code executable on the device is consequently able to display to the user whether plain text data is stored on the device or not.

    摘要: A communication device (and its related method of operation), when accessing password protected voicemail services, may invoke an enhanced security feature which effectively masks at least the password digit values from being discernible by feedback to the user. This is especially important where portable wireless communication devices may have pre-stored password data for use with automated voicemail access—even in a “locked” mode. Unauthorized possessors of such a device might utilize conventional audible feedback during password transmission to decipher the password value. However, such lack of security is avoided by masking the password data values from the audible and/or visual user feedback, if any.

    摘要: A system and method of creating and managing encryption keys in a data processing device generates subsequent encryption keys by combining the existing encryption key with an existing password and seed value. In the preferred embodiment, the initial encryption key is embedded during manufacture and is unknown to the user and manufacturer, thus ensuring that all subsequent encryption keys are derived from an unknown value. When a subsequent encryption key is generated, all data encrypted using the existing encryption key is decrypted using the existing encryption key and re-encrypted using the subsequent encryption key before the existing encryption key is overwritten. In a further aspect, during encryption/decryption the encryption key is combined with the sector address of the data to be encrypted/decrypted in order to generate a unique key for each sector of data to be encrypted/decrypted.

    摘要: A method and system for handling digital certificate status checks are provided. Digital certificate status request data transmitted from a client system is received at a proxy system. The proxy system generates query data for the digital certificate status in response to receiving the digital certificate status request data. The query data is transmitted to a status provider system, and status data from the status provider system in response to the query data is received at the proxy system. Digital certificate status data based on the status data received is generated by the proxy system and transmitted to the client system.
