Abstract

A wireless communicator including a housing, wireless communication functionality located within the housing, and pouching responsive electrical interconnection functionality responsive to pouching orientation of the housing in a pouch of an enhanced function device for causing the wireless communication functionality to authenticate itself to the enhanced function device by (i) generating a random number, A, (ii) encrypting A using a public key of the enhanced function device, (iii) transmitting the encrypted A to the enhanced function device, (iv) receiving an encrypted number, B, from the enhanced function device, encrypted using a public key of the wireless communicator, (iv) decrypting B using a private key of the wireless communicator, (v) encrypting the product A*B using the public key of the enhanced function device, and (vi) transmitting the encrypted A*B to the enhanced function device.

Claims

1. A wireless communicator comprising:

a housing;

wireless communication functionality located within said housing; and

pouching responsive electrical interconnection functionality responsive to pouching orientation of said housing in a pouch of an enhanced function device for causing said wireless communication functionality to authenticate itself to the enhanced function device by (i) generating a random number, A, (ii) encrypting A using a public key of the enhanced function device, (iii) transmitting the encrypted A to the enhanced function device, (iv) receiving an encrypted number, B, from the enhanced function device, encrypted using a public key of the wireless communicator, (iv) decrypting B using a private key of the wireless communicator, (v) encrypting the product A*B using the public key of the enhanced function device, and (vi) further transmitting the encrypted A*B to the enhanced function device.

2. A wireless communicator comprising:

a housing;

wireless communication functionality located within said housing; and

pouching responsive electrical interconnection functionality responsive to pouching orientation of said housing in a pouch of an enhanced function device for causing said wireless communication functionality to authenticate the enhanced function device by (i) receiving an encrypted number, A, from the enhanced function device, encrypted using a public key of the wireless communicator, (ii) decrypting A using a private key of the wireless communicator, (iii) generating a random number, B, (iv) encrypting B using a public key of the enhanced function device, (v) transmitting the encrypted B to the enhanced function device, (vi) further receiving the encrypted number, C, from the enhanced function device, encrypted using a public key of the wireless communicator, and (vii) verifying that C=A*B.

3. A method for a pouchable wireless communicator, comprising, in response to orienting the wireless communicator in a pouch of an enhanced function device, authenticating itself to the enhanced function device, comprising:

generating a random number, A;

encrypting A using a public key of the enhanced function device;

transmitting the encrypted A to the enhanced function device;

receiving an encrypted number, B, from the enhanced function device, encrypted using a public key of the wireless communicator;

decrypting B using a private key of the wireless communicator;

encrypting the product A*B using the public key of the enhanced function device; and

further transmitting the encrypted A*B to the enhanced function device.

4. A method for a pouchable wireless communicator, comprising, in response to orienting the wireless communicator in a pouch of an enhanced function device, authenticating the enhanced function device, comprising:

receiving an encrypted number, A, from the enhanced function device, encrypted using a public key of the wireless communicator;

decrypting A using a private key of the wireless communicator, generating a random number, B;

encrypting B using a public key of the enhanced function device;

transmitting the encrypted B to the enhanced function device;

further receiving the encrypted number, C, from the enhanced function device, encrypted using a public key of the wireless communicator; and

verifying that C=A*B.
