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.
