Providing a user device with a set of access codes

A method for monitoring access code usage, said method comprising:

• a processor in a tool kit operably coupled with a user device and an encryption engine, said processor performing:
• tracking the access code usage of the user device;
• each time the user device uses an access code:
• comparing a number of unused access codes to a predetermined threshold level;
• responsive to the number of unused access codes reaching the predetermined threshold level automatically generating a first message to a server requesting a new set of access codes without any intervening transmission from the user device;
• wherein the server is in wireless communication with the user device;
• wherein the first message is automatically initiated via a wireless channel;
• wherein said first message comprises an identification code associated with an encryption key stored in the server, said identification code used by the server to retrieve said encryption key associated with the user device;
• and
• sending the first message to the server;
• receiving at the tool kit a second message from the server, said second message containing the new set of access codes encrypted with the retrieved encryption key;
• decrypting the new set of access codes using the encryption key stored in the tool kit;
• and
• storing the new set of access codes in the tool kit.

A method for monitoring access code usage, said method comprising:

• a processor in a tool kit operably coupled with a user device, said processor performing:
• tracking the access code usage of the user device;
• comparing a number of unused access codes to a predetermined threshold level after each use;
• responsive to the number of unused access codes reaching the predetermined threshold:
• generating a public/private key pair;
• automatically generating a first message to a server requesting a new set of access codes without any intervening transmission from the user device;
• and
• sending the first message to the server, wherein said first message comprises the public key of the pair and wherein said first message is automatically initiated via a wireless channel;
• wherein the public key is used by the server to:
• generate a session key, encrypt the set of access codes with the session key to produce a session key encrypted set, and encrypt the session key with the public key to produce an encrypted session key,
• at the tool kit:
• receiving a message from the server containing the session key encrypted set and the encrypted session key;
• receiving the encrypted session key;
• decrypting the encrypted session key with the private key of the pair to recover the session key,
• decrypting the session key encrypted set with the recovered session key to recover the set, and
• storing the decrypted set in the tool kit for use by a user of the user device.

An apparatus comprising:

• wireless capability for enabling wireless communication with a server;
• an input/output system;
• and
• a tool kit operably coupled with the apparatus, said tool kit comprising:
• a memory storing an encryption key;
• and
• a processor device operatively coupled with the storage, said processor device configured to perform steps of:
• tracking the access code usage of the user device;
• each time the user devices uses an access code, performing:
• comparing a number of unused access codes to a predetermined threshold level;
• responsive to the number of unused access codes reaching the predetermined threshold, automatically generating a first message to the server requesting a new set of access codes without any intervening transmission from the user device;
• wherein the first message is automatically initiated via a wireless channel;
• including in the first message an identification code associated with an encryption key stored in the tool kit, said identification code used by the server to retrieve the encryption key associated with the user device;
• and
• sending the first message to the server;
• receiving a second message from the server, said second message containing the new set of access codes encrypted with the retrieved encryption key;
• decrypting the new set of access codes with the encryption key from the memory;
• and
• storing the new set of access codes in the storage.
