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 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 system and method for generating reproducible session keys in a wireless messaging system. The session key is generated based on a hash of a message itself, optionally concatenated with additional information. Since the local server stores the message, it can easily regenerate the same session key in response to each MORE request. The method of the invention can be implemented with the stored original message, a public key, and an algorithm for generating the session key based on a hash of the message.

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： Systems and methods for processing encoded messages within a wireless communications system are disclosed. A server within the wireless communications system performs signature verification of an encoded message and provides, together with the message, an indication to the mobile device that the message has been verified. In addition, the server provides supplemental information, such as, for example, a hash of the certificate or certificate chain used to verify the message, to the device, to enable the device to perform additional checks on the certificate, such as, for example, validity checks, trust checks, strength checks, or the like.

摘要： A system and method for generating keys that can be used for encrypting and decrypting PIN messages transmitted between mobile devices. In one embodiment, the method comprises defining a function f, where f(x,y)=f(y,x), and for each of first and second mobile devices, evaluating f with one of x and y having the value of the PIN of the respective mobile device. Each one of the first and second mobile devices can then compute a shared messaging key by evaluating f with the other of x and y having the value of the PIN of the other mobile device. The shared key can then be used specifically to encrypt and decrypt PIN messages transmitted between those two mobile devices.

摘要： A wireless communication system which employs cryptographic functions requiring random data input in a mobile wireless device includes provisions for securely adding randomness to the mobile wireless device. Such added randomness can be securely provided during synchronizing sessions with a device user's base computer via secure wired and/or wireless connections. The new random data can be obtained by software and/or hardware random number generators accessible to the user's base computer and/or from accessible secure external sources (e.g., a secure website source of random data).
