Elliptic curve ElGamal encryption based location privacy-preserving scheme
An elliptic curve ElGamal encryption based location privacy-preserving scheme was proposed to address the location privacy problem of secondary users in collaborative spectrum sensing.Firstly,secondary users encrypted the original sensing reports using the ElGamal public key techniques on the ellipt...

| description | An elliptic curve ElGamal encryption based location privacy-preserving scheme was proposed to address the location privacy problem of secondary users in collaborative spectrum sensing.Firstly,secondary users encrypted the original sensing reports using the ElGamal public key techniques on the elliptic curve and sent them to the trusted property authority.Secondly,the trusted property authority partially decrypted and randomized sensing reports and then sent the randomized sensing reports to the fusion center.Thirdly,the fusion center finally decrypted and got the original sensing reports.Finally,security of the scheme was analyzed.According to the scheme,the encryption method of sensing reports was based on public key cryptography on elliptic curve.And the trusted property authority randomized encrypted sensing reports.Thus the location privacy of secondary users can be protected.Meanwhile,this scheme effectively reduces communication and storage cost,compared with other schemes.In addition,this scheme also has fault tolerant and dynamic mechanism,which increases the practicability and feasibility. |
