Recently, as the utilization of CCTV (closed circuit television) is emerging as an issue, the studies on CCTV are receiving much attention. Accordingly, due to the development of CCTV, CCTV has IP addresses and is connected to network; it is exposed to many threats on the existing web environment. In this paper, steganography is utilized to confirm the Data Masquerading and Data Modification and, in addition, to strengthen the security; the user information is protected based on PKI (public key infrastructure), SN (serial number), andR value(random number) attributed at the time of login and the user authentication protocol to block nonauthorized access of malicious user in network CCTV environment was proposed. This paper should be appropriate for utilization of user infringement-related CCTV where user information protection-related technology is not applied for CCTV in the future.

Purpose The purpose of the study is to develop a secure, efficient, and enhanced user authentication mechanism to achieve reliable and authenticated connection. In online transactions, users and resources are located at different places, and the sensitive information is to be protected and transferred using the suitable, reliable mechanism. Design/methodology/approach One of the latest approach to handle the requirement is by a Public Key Infrastructure (PKI) or its variant Wireless Public Key Infrastructure (WPKI). Fundamental management techniques are required to be very secure and vital since they are one of the points of attack in public key cryptosystem. Entity authentication and key agreement (AKA) is a critical cryptographic problem in wireless communication, where a mutual entity authentication plays a vital role in the establishment of the secure and authentic connection. This paper proposes an efficient and enhanced AKA scheme (EAKA) with the end-to-end security and verifies the proposed system for protection using automated validation of internet security protocols and applications. An efficient way for the implementation of an enhanced version of the protocol is proposed using a lattice-based cryptographic algorithm. Findings The time consumed for the proposed research work shows that it is practical and acceptable. Originality/value The proposed research work is an efficient and enhanced user authentication mechanism.

The large-scale utilization of biometric authentication systems creates a demand for effective and reliable security and privacy of its data. Biometric data is not secret and if compromised, it can have catastrophic effects on the integrity of the whole verification system. To address these issues, this paper presents a novel encryption and watermarking method by using public key infrastructure for the secure transmission of biometric data over network. Encryption is applied on the biometric template before embedding as a watermark to make it more secure and robust and then, it is hid into the cover image. Experimental results show that the security, performance, and accuracy of the presented method is encouraging comparable with the other methods found in the current literature.

The cloud based services today offers a large amount of services irrespective of the geographical location to individuals or a group. This opens the way to new security dangers to the protection and also the integrity of the information put away. Public Key Infrastructure mechanism, advanced endorsements, computerized marks are existing techniques to accomplish numerous security prerequisite sites, however late dangers make them powerless against genuine assaults when utilized without earlier trust-point establishments. At the time of open reviewing of the information by Third Party Auditor, it is quite possible that it might trade off in protecting client’s privacy. This outcome in two separate issues which represents the dangers of authentication and additionally the trustworthiness of the information that is being shared. In this paper, we propose a Noble Authentication Protocol with privacy preservation policy cloud that gives solid common verification framework utilizing the Pedersen Commitment scheme alongside using ring signature algorithm calculations that will authenticate the TPA and just give the essential data to checking the trustworthiness of the mutual information with keeping the privacy of the clients covered up. The proposed technique helps in staying away from conceivable hash crashes, approving the chain of trust to certificate authorities and different denial records.

With the rising popularity of the Internet and the development of big data technology, an increasing number of organizations are opting to cooperate across domains to maximize their benefits. Most organizations use public key infrastructure to ensure security in accessing their data and applications. However, with the continuous development of identity-based encryption (IBE) technology, small- and medium-sized enterprises are increasingly using IBE to deploy internal authentication systems. To solve the problems that arise when crossing heterogeneous authentication domains and to guarantee the security of the certification process, we propose using blockchain technology to establish a reliable cross-domain authentication scheme. Using the distributed and tamper-resistant characteristics of the blockchain, we design a cross-domain authentication model based on blockchain to guarantee the security of the heterogeneous authentication process and present a cross-domain authentication protocol based on blockchain. This model does not change the internal trust structure of each authentication domain and is highly scalable. Furthermore, on the premise of ensuring security, the process of verifying the signature of the root certificate in the traditional cross-domain authentication protocol is improved to verify the hash value of the root certificate, thereby improving the authentication efficiency. The developed prototype exhibits generality and simplicity compared to previous methods.
