摘要： A system and method for verifying a digital signature on a certificate, which may be used in the processing of encoded messages. In one embodiment, when a digital signature is successfully verified in a signature verification operation, the public key used to verify that digital signature is cached. When a subsequent attempt to verify the digital signature is made, the public key to be used to verify the digital signature is compared to the cached key. If the keys match, the digital signature can be successfully verified without requiring that a signature verification operation in which some data is decoded using the public key be performed.

摘要： A mobile wireless communication device also has at least one wired communication port. Enhanced security is achieved by permitting the device to automatically disable one or more wireless ports when connected to a wired port. Specific combinations/permutations of such automatic control may be effected by use of an IT Policy also resident on the device.

摘要： A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret. First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.

摘要： A challenge response scheme includes the authentication of a requesting device by an authenticating device. The authenticating device generates a challenge that is issued to the requesting device. The requesting device combines the challenge with a hash of a password provided by a user of the requesting device, and the combination of the hash of the password and the challenge is further hashed in order to generate a requesting encryption key that is used to encrypt the user supplied password. The encrypted user supplied password is sent to the authenticating device as a response to the issued challenge. The authenticating device generates an authenticating encryption key by generating the hash of a combination of the challenge and a stored hash of an authenticating device password. The authenticating encryption key is used to decrypt the response in order to retrieve the user-supplied password. If a hash of the user-supplied password matches the stored hash of the authenticating device password, then the requesting device has been authenticated and the authenticating device is in possession of the password.

摘要： Systems and methods for processing encoded messages within a wireless communication system. A server within the wireless communication system provides one or more indications to a mobile device as to certain conditions existing with respect to an encoded message. The mobile device performs a different message processing function based upon whether the indication is provided. The indications may include indicating whether a message exceeds a message size threshold and/or may indicate whether a partial message is being sent.

摘要： A method for securing data and resetting a password using a content protection key is provided, in which the content protection key itself is protected by a password. A content protection key is also protected at a data storage device with a key encryption key generated in collaboration with an additional device such as a server. The server stores a private key required to regenerate the key encryption key, but this private key is not provided from the server to the data storage device; rather, a public key derived from the private key is provided by the server. The data storage device combines the received public key and a further private key to derive the key encryption key; the further private key itself is not stored by the data storage device, but rather its matching public key is stored. The content protection key is then encrypted using a password and the derived key encryption key. If the password is lost, data from the server and from the data storage device may be combined to recreate the key encryption key.

摘要： Embodiments of a system and method for providing additional security for data being transmitted across a wireless connection that has been established using a known wireless protocol (e.g. Bluetooth) are described. An encryption key is exchanged between a computing device (e.g. a mobile device) and a wireless peripheral output device (e.g. a printer, a headset). In exemplary embodiments, the encryption key is generated at the peripheral output device. Data associated with the encryption key is output at the peripheral output device, which can be input by the user at the computing device. The encryption key is then recovered at the computing device from the input, thereby completing the key exchange. The encryption key can then be used to encrypt and decrypt data transmitted over the established wireless connection, providing additional security.

摘要： Embodiments relate to systems and methods for implementation on a mobile device to force the mobile device into a secure state upon detection or determination of a triggering event. Once it is determined that a triggering event has occurred, each application operating on the mobile device is caused to immediately unreference sensitive objects and a secure garbage collection operation is performed upon the unreferenced sensitive objects to render data associated therewith unreadable. The mobile device is then caused to enter a secure state, in which the mobile device cannot be accessed without authorization. A microprocessor within the mobile device is configured to determine the existence of the triggering event according to a configuration data structure and to perform the secure garbage collection.

摘要： A system and method that facilitates the authentication of streamed data received at a device, where authentication information is not distributed over the data stream. One embodiment of a method of authenticating data comprises the steps of: receiving, at the device, data in a plurality of packets transmitted by a data server; submitting a request for a server-computed authentication value to a data authentication server, wherein the data authentication server is adapted to compute the server-computed authentication value based on a subset of the data transmitted by the data server; receiving, at the device, the server-computed authentication value from the data authentication server in response to the request; computing a device-computed authentication value based on a subset of the data received at the device corresponding to the subset of the data transmitted by the data server; and determining if the subset of the data received at the device is authentic by comparing the server-computed and device-computed authentication values.
