摘要:
A cryptographic key is used to secure a communication link between a first device and a second device. Generating the cryptographic key is accomplished by a) generating a first cryptographic key, b) generating a second cryptographic key, c) applying a hash function to packets transmitted over the communication link to create a hash result, and d) applying the hash function to the first cryptographic key, the second cryptographic key and the hash result.
摘要:
A system includes a server, a first client device to communicate in an authenticated and secured manner with the server over a first communication link, and a second client device to communicate in an authenticated and secured manner with the first client device over a second communication link. The first client device is to cause the server and the second client device to share cryptography information. The cryptography information may then be used to secure a third communication link between the server and the second client device that does not include the first client device.

A device coupled to a smart card reader may request random data from a smart card inserted into the smart card reader, and the smart card reader may incorporate the random data into its randomness pool. A device having a source of random data may have a driver installed thereon for another device and the driver may extract random data from the source and transmit it securely over a wireless communication link to the other device. The other device, which may be a smart card reader, may incorporate the extracted random data into its randomness pool. A smart card reader may incorporate traffic received from a smart card inserted therein into its randomness pool.

An active new password entry dialog provides a compact visual indication of adherence to password policies. A visual indication of progress towards meeting all applicable password policies is included in the display and updated as new password characters are being entered. A visual hint associated with at least one applicable password policy that has not yet been satisfied is also included in the display. An ability to obtain more detailed comprehensive password policy information is also permitted upon user command (e.g., including an indication whether each password policy has yet been met or unmet). Preferably the displayed hint and associated applicable password policy not yet satisfied is randomly changed during entry of a new password (e.g., upon the entry of each new password character).

摘要:
A system includes a first wireless-enabled device that transparently stores confidential information and a second wireless-enabled device that stores the same confidential information. The confidential information is to be used to secure a wireless communication link between the first device and the second device. One or both of the first device and the second device is to delete the confidential information upon fulfillment of one or more conditions related to the communication link.
摘要:
Different target transmit powers are determined for different wireless transmissions from a wireless device, the different transmissions having different security requirements. For example, the security requirements of a particular transmission may include a security ranking of a device to which one or more frames carried by the particular transmission are addressed. In another example, the security requirements of a particular transmission may include the confidentiality of data carried by the particular transmission.
摘要:
A first device has a display that is able to show information. The information is to be exchanged with a second device. The information is cleared from the display following receipt of an indication from the second device that the information has been successfully inputted at the second device.

A communication system is provided with program logic for enforcing an IT Policy specifying suitable encryption encoding levels for corresponding security classification levels (and/or encryption strengths).

In one embodiment, a scheme is provided for managing secure registration of a mobile communications device. Upon being provided with an upgraded registration process that requires encryption, the mobile communications device has the option of continuing to register with a network node using a downgraded registration process within a specified time window which involves unencrypted registration requests and responses. Thereafter, the mobile communications device is operable to select between the upgraded and downgraded registration processes.
