Abstract
An access system includes a transmitter and a receiver for exchange of secure data wherein the system uses an encryption and a decryption algorithm to exchange a secure data packet. The secure data packet may include an unencrypted data packet and an encrypted data packet. The encrypted data packet may include first data encrypted by the encryption algorithm, and data decrypted by the decryption algorithm, wherein the data decrypted by the decryption algorithm includes a combination of a secure signature and second data encrypted by the encryption algorithm.
