Abstract

The invention discloses a method for transferring the ownership of a radio frequency identification label based on quadratic residue. The method comprises the following specific steps: (1) a transfer reader and a receiving reader authenticate each other to confirm mutual identities; (2) the transfer reader sends a public key of the receiving reader to the radio frequency identification label; (3) the transfer reader sends the information of the radio frequency identification label to the receiving reader; (4) the receiving reader negotiates a new shared key with the label; and (5) the receiving reader establishes communication with the label by using the new shared key. According to the method disclosed by the invention, the ownership of an electronic label is transferred between the transfer reader and the receiving reader, thereby effectively reducing the calculated amount and occupied resources of the electronic label, guaranteeing the communication security at the same time, and being better applicable to low-cost radio frequency identification systems.

Description

technical field

[0001] The invention belongs to the technical field of communication, and further relates to a radio frequency identification RFID (Radio Frequency Identification) tag ownership transfer method based on secondary residue in the technical field of information security. The invention can realize the conversion of the shared secret key between the old mobile reader and the radio frequency tag, thereby ensuring the safe transfer of the ownership of the radio frequency tag. Background technique

[0002] At present, the existing methods for transferring the ownership of radio frequency tags can be roughly divided into two categories: methods based on non-public key encryption and methods based on public keys. Among them, the ownership transfer protocol based on public key can achieve higher security, but increases the overhead of radio frequency tags; the ownership transfer protocol based on non-public key encryption reduces the overhead of radio frequency tags, bu...

Embodiment Construction

[0073] Attached below figure 1 , to further describe the specific steps of the present invention.

[0074] Step 1, send a request message.

[0075] The transfer reader generates a random number N 1 .

[0076] The transferring reader queries the identity information of the receiving reader from the database.

[0077] Using the modulus formula of the quadratic remainder, calculate the modulus of the identity information of the receiving reader and the random number generated by the transferring reader, and obtain the encrypted request message.

[0078] The modulo formula of the quadratic remainder is as follows:

[0079] m 1 =(A||B) 2 mod n 1

[0080] Among them, M 1 Indicates the encrypted message, A indicates the identity information of the receiving reader, || indicates the message cascade operation, B indicates the random number generated by the transfer reader, (·) 2 Represents square operation, mod represents modulo operation, n 1 Indicates the public key of the...
