Abstract:
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.
