    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: During generation of an implicit certificate for a requestor, a certificate authority incorporates information in the public-key reconstruction data, where the public-key reconstruction data is to be used to compute the public key of the requestor. The information may be related to one or more of the requestor, the certificate authority, and the implicit certificate. The certificate authority reversibly encodes the public-key reconstruction data in the implicit certificate and sends it to the requestor. After receiving the implicit certificate from the certificate authority, the requestor can extract the incorporated information from the public-key reconstruction data. The implicit certificate can be made available to a recipient, and the recipient can also extract the incorporated information.

    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 system and method for processing certificates located in a certificate search. Certificates located in a certificate search are processed at a data server (e.g. a mobile data server) coupled to a computing device (e.g. a mobile device) to determine status data that can be used to indicate the status of those certificates to a user of the computing device, without having to download those certificates to the computing device in their entirety. The data server is further adapted to transmit the status data to the computing device. In one embodiment, at least one status property of the certificates is verified at the data server in determining the status data. In another embodiment, additional certificate data is determined and transmitted to the computing device, which can be used by the computing device to verify, at the computing device, at least one other status property of the certificates.

    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: Increasing security for a hand-held data processing device with communication functionality where such a device includes an access-ordered memory cache relating to communications carried out by the device. The hand-held data processing device has a locked state that is entered by the device receiving or initiating a trigger. On occurrence of the trigger to enter the locked state the memory cache is reordered so as to disrupt the access-ordering of the cache to obscure device traffic information and thus increase the security of the device in the locked state.

    摘要: A system and method for associating message addresses with certificates, in which one or more secondary message addresses are identified and associated with a user-selected certificate. The secondary message addresses are saved in a data structure that resides in a secure data store on a computing device, such as a mobile device. When a message is to be encrypted and sent to an individual using a particular certificate, an address mismatch would not be detected so long as the address to which the message is to be sent matches any of the message addresses associated with the certificate. The message addresses associated with the certificate include any message addresses contained within the certificate itself (“primary message addresses”) as well as any secondary message addresses that have been subsequently associated with the certificate.
