System and method for remote opening of handicap access doors

A receiver for an automatic door assembly having a door and an actuator coupled to the receiver for automatically opening and closing the door in response to an activation signal, said receiver comprising:

• a receiver circuit for receiving a rolling code control signal from a remote transmitter;
• and
• a control circuit coupled to the actuator and said receiver circuit, wherein said control circuit is configured to decrypt any received rolling code control signal using a specific public key and to determine whether any received consecutive hopping codes are decrypted that correspond to consecutive codes of a rolling code algorithm, said control circuit supplies the activation signal to the actuator when any received consecutive hopping codes are decrypted that correspond to consecutive codes of the rolling code algorithm.

A transmitter for remotely activating an automatic door unit having a door, an actuator for automatically opening and closing the door in response to an activation signal, and a receiver coupled to the actuator for supplying the activation signal in response to the receipt of a rolling code control signal having consecutive hopping codes that correspond to consecutive codes of a rolling code algorithm, said transmitter comprising:

• a transmitting circuit for transmitting control signals;
• and
• a control circuit for generating and encrypting a rolling code control signal using a public key, the rolling code control signal including a plurality of consecutive hopping codes the sequence of which is determined in accordance with the same rolling code algorithm used by the receiver.
