    摘要: 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 the smart card reader. The device may generate a random session key to encrypt traffic between the device and the smart card reader. The device may send an encrypted version of the random session key to the smart card reader. The smart card reader may decrypt the encrypted version and incorporate the random session key into its randomness pool. A smart card reader may incorporate random data received from a smart card inserted therein into its randomness pool.

    摘要: Systems and methods for processing messages within a wireless communications system are disclosed. At least part of an encrypted message is received at a device for which it is intended. A security indicator on the device indicates that a message is encrypted. The message is decrypted, and it is determined whether the decrypted message includes a logical attachment. If there is such a logical attachment, an attachment indicator on the device indicates that the encrypted message includes an attachment associated with the message independent of the encryption attachment itself. The indicators may be updated via direct user action, or transparently and free from direct user input to said device.

    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 method for processing security communication protocol compliant signed receipts at a mobile communication device linked to a host system is provided. The host system receives an email message linked to a digital signature, and a signed receipt. The host system redirects the signed receipt to the mobile communication device. The host system determines if the email message is available at the mobile communication device, and if not, the host system retrieves the email message and redirects the email message to the mobile communication device. The mobile communication device can then verify the signed receipt based on the email message. Optionally, rather than the email message, the host system retrieves and/or recalculates data elements associated with the email message and required to verify the signed receipt, and redirects these data elements to the mobile communication device. A related system is provided, as well as server computer program for the host system, and device computer program for the mobile communication device.

    摘要: 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.
