This article proposed the authentication protocol for peer-to-peer resource sharing community. The proposed protocol does not require a priori information for generating and exchanging authentication key. Also this protocol can provide the delicate access control by allowing the user(authenticator) to assign the trust level to the authentication supplicant, which can be used to decide if the resource providing node will accept the resource sharing request from a resource requesting node. Trust Relationship Chaining provides the environment where trust levels (included in the trust table) of nodes in the resource sharing community are propagated among nodes when trust tables are exchanged between two nodes engaged in mutual authentication process and authentication refresh so that any two nodes which are not directly mutual-authenticated can assign the trust level each other for the access control for resource sharing. In the proposed protocol a node can implements the authentication refresh continuously to verify the effectiveness of authentication after mutual authentication so that the authentication of new node or authentication revocation(effectiveness cancellation) of the departed node can be propagated to the all the nodes in RSC and eventually safe resource sharing community is configured.

Although smartwatches are different from smartphones in shape and carried method, they are also highly relevant to smartphones and have similar characteristics. This paper studied the impact of using smartphones on the intention to use smartwatches from the perspective of brand extension. The hypotheses were that the major factors of the attitude formed in the process of using smartphones affect the intention of using them and affect the trust of smartwatches. As a result of testing the hypotheses, trust in smartphonees affected trust in smartwatches. And the intention to use smartphones and the trust of smartwatches affected the intention to use smartwatches. However, the satisfaction, familiarity, and favorability of smartphones did not affect the trust of smartwatches. Smartwatches were associated with smartphones but they had independent characters. Based on the results of the study, the trust of smartwatches is very important, so the corporate managers need to find ways to improve their trust. And they should find strategies to improve the value of the product by finding out the factors that can increase the intention of using smartwatches.

Digital accredited certificates issued under the Digital Signature Act provide essential functionalities for online service, so certificates are used for various services such as online banking, e-government. However, certificates can be stolen by hackers and users need to install separate software to use certificates. Recently FIDO, which aims to solve the problems of password-based authentication and the lack of interoperability between authentication methods, is used for biometric authentication and TrustZone, hardware-based secure environment, is used for safe smartphone usage. In this paper, the new service method is suggested which uses FIDO-based biometric authentication and stores certificates in TrustZone. This method can not only improve security and convenience but also be easily applied to the service because it uses built-in functionalities of new smartphones such as biometric sensors and TrustZone. It is expected that people can use certificates in a safe and convenient way with this method.

Mobile Ad Hoc Network is easy to be attacked because nodes are distributed not network based infrastructure. Intrusion detection system perceives the trust values of neighboring nodes and receives inspection on local security of nodes and observation ability. This study applied clustering mechanism to reduce overhead in intrusion detection. And, in order to measure the trust values, it associates the trust information cluster head received from member nodes with its own value and evaluates the trust of neighboring nodes. Secure data transmission is received by proposed concept because the trust of nodes on network is achieved accurately.

An experiment was conducted to investigate the relationship between the DVEs and subtitles provided with anchor speech in TV news and the news evaluation, trust and agenda recognition. 120 university students were asked to watch four types of news that differed in the contents of their DVEs and subtitles, and then they evaluated the fairness, sensibility, and irritability of the news. The content of DVEs and subtitles were related to the irritability evaluation and trust of the news, and it was not related with the fairness and sensibility evaluation. When the DVEs and subtitles emphasizing the stimulating aspects of the issue were given, the irritability was highly evaluated and the trust was low. The evaluation on news fairness affected the news trust. The more they rated news as fair, the greater the trust in news. Unlike the assumption in this study, DVEs and subtitles were not the main factors influencing the news agenda perception, and the viewers tended to perceive the agenda based on the news content itself.

We study how the three antecedents of trust such as integrity, ability and benevolence affect trust building, based on the articles extracted from the New York Times during 1981-2010. Major findings are that the ratio of negative impact on trust from integrity is 86%, whereas the ratios of positive impact on trust from ability and benevolence are 70% and 71% respectively. Statistical tests show that the hypothesis that the negative impact of integrity on trust build-up will be higher is supported, but the most unstructured benevolence related hypotheses are not confirmed due to small sample sizes. Based on the study, we suggest that the future direction of IT application should accommodate benevolence factor seriously to fulfill corporate social responsibility.

The development of information technology and the demands of society on an application in an operating system, as well as increasing the specifications and sophistication of smartphones, require banks to make changes to their mobile banking applications. The transformation of the mobile banking application into a digital banking application conducted by banks has made users re-evaluate based on their preferences. This study presents the behavior of users of digital banking applications in Yogyakarta, Indonesia. The hypothesis model is based on Technology Acceptance Model (TAM) with additional factors of the social image, perceived risk and perceived trust adopted from Muñoz-Leiva et al. (2017). The methodology in this study includes data collection through questionnaires distributed online and data analysis using the Structural Equation Model. The results of this study illustrate that the perceived trust and perceived risk have a more dominant part in influencing user attitude and user intention to use digital banking. Meanwhile, social image, perceived ease-of-use and perceived usefulness are not significant in influencing user attitude and user intention to use digital banking. The implication of this research helps to determine the right communication and strategy so that more users with more benefits can utilize this digital banking application.
