  • Patent number: 8132010
    Abstract: An authentication system determines if a counterfeit ineligible unit is installed in a main device. When connected with a battery pack, a notebook PC generates and combines a random number and a function determination signal using a signal combining unit and transmits same to the battery pack. A first function calculation unit calculates the function of the random number. The battery pack has a signal separation unit to separate the combined signal into the random number and function determination signal, and a second function calculation unit to calculate the function of the random number for transmitting back to the notebook PC. A comparison unit compares the calculation results by the first and second function calculation units to determine whether the connected battery pack is an authorized one and denies connection if the pack is an unauthorized one.

  • Publication number: 20050108309
    Abstract: An authentication system is provided, which prevents any glitches or accidents caused by a counterfeit ineligible unit being installed in a main device. When connected with a battery pack (an authenticated unit), a notebook PC (an authenticating device) allows a random number and a function determination signal to be generated and then combined by a signal combining unit to be transmitted to the battery pack. Meanwhile, a first function calculation unit calculates the function of the random number. The battery pack allows a signal separation unit to separate the combined signal into the random number and function determination signal, and a second function calculation unit to calculate the function of the random number for transmitting back to the notebook PC. A comparison unit compares the calculation results by the first and second function calculation units to determine whether the connected battery pack is an authorized one.
