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 method and apparatus for processing digitally signed messages in which address mismatch errors are detected. In at least one aspect, the number of address mismatch errors reported to a user for a message may be minimized for messages that properly incorporate message portions signed by someone other than the sender of the message, as may be the case where the message contains a conversation thread for example, by performing at least one predetermined action for digital signatures corresponding to signed data appearing after a message separator. The message separator may indicate that the message contains data from an older forwarded message or from an older message that has been replied to, for example. The at least one-predetermined action may comprise bypassing verification of address matches for those digital signatures, or verifying address matches for those digital signatures but suppressing user notification of any address mismatch errors, for example.
摘要翻译：一种用于处理其中检测到地址不匹配错误的数字签名消息的方法和装置。在至少一个方面中，针对消息的用户报告的地址不匹配错误的数量可以被最小化，以适当地合并由消息的发送者以外的其他人签名的消息部分的消息，如可以是消息包含例如，通过对与消息分离器之后出现的签名数据相对应的数字签名执行至少一个预定动作。消息分隔符可以指示该消息包含来自较旧转发消息的数据，或者包含已被回复的旧消息。所述至少一个预定动作可以包括绕过对那些数字签名的地址匹配的验证，或验证那些数字签名的地址匹配，但抑制用户对任何地址不匹配错误的通知。

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).

摘要： A user device and method for securely sending messages to a recipient. The device and method initiate a search for a certificate needed to encrypt a message to a particular recipient prior to receiving a send instruction from the user. The device may determine when a user changes the recipients for the message and, as the user composes the message, determine whether the requisite certificates are stored locally on the device or need to be obtained from a remote source. If the certificates required are not on the device, then a search of the remote source is initiated. The detection of changes to the recipient list and the initiation of any required searches occurs prior to receipt of a send instruction from the user.

摘要： A method for preventing a recipient of an electronically transmitted message from taking at least one action in relation to the message is disclosed. The message has at least two parts with one of the parts having a higher level of security than the other part. The method includes the step of extracting information from the message. The information indicates that the higher level security part is not permitted to have the action taken on it while the other part is so permitted. The method also includes the step of preventing the higher level security part from having the action taken on it in reaction to said recipient making an offending request.

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 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 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.
