Claim:
1. A method for communicating between a master device and a slave device using a first single conductor, the method comprising: transmitting a first ping on the first single conductor using a master device, the first single conductor configured to couple the master device to a slave device; receiving a slave ping on the first single conductor at the master device during a ping interval; authenticating the slave device after receiving the slave ping, wherein the authenticating includes: transmitting a random number from the master to the slave; receiving an encrypted number from the slave; decrypting the encrypted number to provide a decrypted number; and indicating a valid authentication if the decrypted number matches the random number; transmitting data packets from the master device to the slave device using the first single conductor, wherein transmitting data packets includes toggling a logic level of the first single conductor prior to sending a first data packet using pulses having a duration of less than one half of a unit interval, wherein the unit interval defines a single bit duration of transmitted data; and wherein a ping, including the first ping and the slave ping, includes a duration of more than a unit interval.
