Study On Airborne Wireless Network Authentication Mechanism For Passenger Boarding Bridge’s AP

In order to solve the problem of no unified security mechanism in the data transmission process of Airborne Wireless Network Authentication Mechanism for Passenger Boarding Bridge’s AP,a security authentication method with strong security and perfect mechanism is proposed.The main innovations are as follows:(1)A new ID-based blind signature scheme is proposed firstly in combination with the Elgamal algorithm.The signer is invisible to the original message and cannot restore it through signature.Using a hash function to process private keys and ID which is safe under the ROM and is attribution to DLP.(2)An identity authentication scheme is proposed based on ECC.Use non-repeating pseudo-random sequences to ensure the freshness of random numbers.The formal analysis of the SVO logic shows that this scheme can achieve two-way authentication and ensure secure access during data transmission.(3)Using the bilinear pairing technology,an improved IDAK protocol is proposed.The use of certificateless and unmanaged modes effectively saves system resources and has all the security attributes required for key agreement protocols.The proposed blind signature,identity authentication and key agreement scheme was first applied to the civil aviation information system(the TWLU data transmission prototype system)for simulation,which fills the gaps in domestic research in this field.The blind signature scheme can effectively defend against key recovery attacks and signature forgery attacks;The authentication technology can resist replay attacks and achieve bidirectional authentication;the key agreement scheme can effectively resist security threats such as key leak attack and known key attack.The proposed three schemes improve the security of the TWLU data transmission process,and are more suitable for the civil aviation information system.
