Abstract:
Objective To propose a hybrid encryption algorithm involving in elliptic curve cryptography (ECC) and advanced encryption standard (AES) to solve the problems of wiretapping and tampering of medical data in wireless channel transmission.Methods The sender used AES session key for medical data encryption and ECC public key for AES session key,and applied SHA-1 to obtaining the information summary of medical data and ECC public key to gaining information summary signature.The recipient employed ECC private key to verify the signature and then to decrypt AES session key,and finally decrypt medical data with AES session key.Results The proposed security solution gained advantages over the conventional ECC algorithm and hybrid cryptographic algorithm of RSA and AES in encryption and decryption time,safety strength and energy consumption,so that the confidentiality and integrity of medical data could be ensured during transmission.Conclusion The hybrid encryption scheme can meet the requirement of wireless medical sensor network in low time complexity,and realizes the protection of the patient data and privacy.
