Privacy protection for telecare medicine information systems using a chaotic map-based three-factor authenticated key agreement scheme

Telecare Medicine Information Systems (TMIS) provides flexible and convenient e-health care. However the medical records transmitted in TMIS are exposed to unsecured public networks, so TMIS are more vulnerable to various types of security threats and attacks. To provide privacy protection for TMIS, a secure and efficient authenticated key agreement scheme is urgently needed to protect the sensitive medical data. Recently, Mishra et al. proposed a biometrics-based authenticated key agreement scheme for TMIS by using hash function and nonce, they claimed that their scheme could eliminate the security weaknesses of Yan et al.’s scheme and provide dynamic identity protection and user anonymity. In this paper, however, we demonstrate that Mishra et al.’s scheme suffers from replay attacks, man-in-the-middle attacks and fails to provide perfect forward secrecy. To overcome the weaknesses of Mishra et al.’s scheme, we then propose a three-factor authenticated key agreement scheme to enable the patient enjoy the remote healthcare services via TMIS with privacy protection. The chaotic map-based cryptography is employed in the proposed scheme to achieve a delicate balance of security and performance. Security analysis demonstrates that the proposed scheme resists various attacks and provides several attractive security properties. Performance evaluation shows that the proposed scheme increases efficiency in comparison with other related schemes

An Efficient Authentication Protocol Based on Chebyshev Chaotic Map for Intelligent Transportation

For meeting the demands of safety, traffic management, and high mobility, vehicular adhoc network (VANET) has become a promising component for smart transportation systems. However, the wireless environment of vehicular network leads to various challenges in the communication security. Hence, several authentication schemes have previously been proposed to address VANET security issues but their procedures disregard the balance between effectiveness and security. Thus, this paper presents a new decentralized authentication protocol that relies on lightweight functions such as the Chebyshev chaotic map and logical shift operator to achieve the high mobility requirement. In order to reduce the number of messages transferred over the network, this protocol attempts to eliminate any redundant authentication steps during its authentication stage. Additionally, the new protocol solves key management problems by applying a little modification to the public key infrastructure to ignore certificates transmission over the network. The proposed design incorporates the self-authentication concept to safeguard the vehicle trip route on the road. Moreover, the performance evaluation is conducted to verify that the proposed protocol outperforms the most related scheme in terms of security and efficiency aspects. Finally, the Scyther simulation validates the security robustness of the new protocol

Image based ECC Mutual Authentication Scheme for Cloud Assisted TMIS

In this modern era, cloud-based services like e-commerce, e-gate, and so on provide immense services to humans.    Healthcare centers are gradually moving to cloud-based services. In which, both the hospital and patients are connected remotely online and patient gets treatment quickly. Increasing the demand in Telecare Medical Information System (TMIS) needs to ensure the security and privacy of the healthcare centers and patients’ information. In this paper, we have proposed an e?cient and provably secure Elliptic Curve cryptography image based mutual authentication scheme for cloud assisted TMIS. The proposed authentication schemes ensure the secured treatment provided to patients from healthcare center through online. The patient can upload their health condition data to cloud via mobile device for the treatment.  The proposed authentication scheme required minimum computational cost with minimum communication overhead. The proposed authentication scheme preserves patient anonymity and withstands the known and chosen plaintext attack. The security analysis for the proposed scheme shows that the proposed authentication scheme is more secure. It shows that the proposed authentication scheme is performing well compare to the related authentication schemes
