Abstract: Provided is a binding update method in MIPv6 which includes: a first step of generating, with a mobile node, a HoTI (Home Test Init) message and transmitting the HoTI message to a corresponding node; a second step of generating a CoTI (Care of Test Init) message and transmitting the CoTI message to the corresponding node; a third step of generating, with the corresponding node, a HoT (Home of Test) message and transmitting the HoT message to the mobile node; a fourth step of generating a CoT (Care-of Test) message and transmitting the CoT message to the mobile node; a fifth step of generating, with the mobile node, a BU (Binding Update) message and transmitting the BU message to the corresponding node; and a sixth step of verifying, with the corresponding node, the BU message and transmitting a BA (Binding Ack) message to the mobile node.

Abstract: A binding update method in MIPv6 is provided which includes: a first step of allowing a mobile node to generate 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 to transmit the HoTI message to a corresponding node through a home agent along with a first index; a second step of allowing the mobile node to generate 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 to transmit the CoTI message directly to the corresponding node along with a second index; a third step of allowing the corresponding node to generate a HoT (Home of Test) message including a first nonce and to transmit the HoT message to the mobile node through the home agent; a fourth step of allowing the corresponding node to generate a CoT (Care-of Test) message including a second nonce and to transmit the CoT message to the mobile node; a fifth step of allowing the mobile node to generate a BU (Binding Update) message by adding the first prime number to the first nonce and the second nonce included in the HoT message and the CoT message and to transmit the BU message to the corresponding node; and a sixth step of allowing the corresponding node to verify the BU message using an exclusive OR operation and a factorization operation in prime numbers with the first prime number and to transmit a BA (Binding Ack) message to the mobile node.
