Patent ID: 8145906

Claim:
A binding update method in MIPv6, comprising: a first step of generating, with a mobile node, a HoTI (Home Test Init) message including a HoA (Home Address) encoded with a product of a first prime number and a second prime number and transmitting, with the mobile node, the HoTI message to a corresponding node through a home agent along with a first index; a second step of generating, with the mobile node, a CoTI (Care of Test Init) message including a CoA (Care-of Address) encoded with a product of the first prime number and a third prime number and transmitting, with the mobile node, the CoTI message directly to the corresponding node along with a second index; a third step of generating, with the corresponding node, a HoT (Home of Test) message including a first nonce and transmitting, with the corresponding node, the HoT message to the mobile node through the home agent; a fourth step of generating, with the corresponding node, a CoT (Care-of Test) message including a second nonce and to transmit transmitting, with the corresponding node, the CoT message to the mobile node; a fifth step of generating, with the mobile node, a BU (Binding Update) message by adding the first prime number to the first nonce and the second nonce included in the HoTI message and the CoTI message and transmitting, with the mobile node, the BU message to the corresponding node; and a sixth step of verifying, with the corresponding node, the BU message using an exclusive OR operation and a factorization operation in prime numbers with the first prime number and transmitting, with the corresponding node, a BA (Binding Ack) message to the mobile node.
