This program is a useful tool for cellular phone industry, TDMA and CDMA network engineers and security managers, as well as everyone who is involved in developing and testing the TDMA and CDMA handsets with the built-in authentication function based on the CAVE algorithm as defined in IS-54 (Appendix A), TSB50, TSB51, IS-95, IS-136 and TIA-627 standards.Now everyone can create a valid authentication key (A-Key), 0 to 20 digits long, with an accompanying 6 digit cheksum calculated for any given ESN number.

The generated sequence of digits can be entered from the phone's keypad to reprogram the phone's A-Key for testing purposes or mobile phone activation.

Otherwise the phone will display "INVALID" which means that either the last 6 digits of A-Key are not correct or there is a problem with the phone.

With this program you can also validate an existing A-Key for any particular ESN number.

The registered copy of the program contains a very useful ESN file processing function.

You will be able to generate huge subscriber A-Key lists for unlimited number of ESN's.

This function will generate a unique 20-digit random A-Key value with corresponding 6-digit checksum for each hexadecimal ESN on the list.
