Abstract
A system for delivering a security code to a cellular telephone. The cellular telephone holds a key X. The cellular telephone requests that an Authorization Center, AC, assign a security code to the cellular telephone. The AC selects a security code, and encrypts it, such that key X is effective to de-crypt the code, yet the AC does not know key X.
