The target of managing electronic records should be the trusted record services to the end-users. The natural characteristics of electronic records yields the drawback in the authenticity aspect and in the integrity aspect, and current standards and methodologies have beed developed to treat this drawback. However the authenticity and the integrity concepts is hardly separated each other and too completed, so alternative "source" concept is introduced and a verification strategy for the origin of electronic records is discussed in this paper. According to this concept, current standards and methodologies may be criticized for the negligence of necessary information organizing/verification, the doubtful long-term verification, and the missing counter-strategy for the verification-failed records. To solve this, needed facters for origin verification is described, new preservation format divided into temporally-fluctuating (variable) part and immutable (fixed) part is proposed, and a strategy to prevent, avoidance, and detection/recovery important records is suggested.

This study aims to examine the effect of employees' CSR perception on creativity via compassion along with the moderating effect of CSR authenticity. For the research procedure, frequency analysis and CFA analysis were performed after sample collection, hypothesis verification and moderating effect verification were performed. We conducted an empirical analysis using 360 employees from large-sized companies in Korea. First, the results showed that CSR perception was positively related to employees' compassion. Second, compassion was also positively related to creativity. Third, the positive relationship between CSR perception and creativity was mediated by compassion, and the aforementioned mediated relationship was moderated by CSR authenticity. Therefore, our study findings imply that, when employees perceive CSR, they will not only form compassion emotions but also will display more creativity especially when they perceive the authenticity of CSR.

Electronic Records need to be appraised the authenticity as well as the value itself. There has been various kinds of discussion about how records to be appraised the value of themselves, but there's little argument about how electronic records to be appraised the authenticity of themselves. Therefore this article is modeling some specific authenticity appraisal methods and showing each stages those methods should or may be applied. At the Ingest stage, integrity verification right after records creation in the organization which produced the records, quality and integrity verification about the transferred in the organization which received the records and integrity check between SIP and AIP in the organization which received and preserved the records are essential. At the Preservation stage, integrity check between same AIPs stored in different medium separately and validation of records where or not damaged and recovery damaged records are needed. At the various Processing stages, suitability evaluation after changing the record's management control meta data and changing the record's classification, integrity check after records migration and periodical validation and integrity verification about DIPs are required. For those activities, the appraisal methods including integrity verification, content consistency check, suitability evaluation about record's meta data, feasibility check of unauthorized update and physical status validation should be applied to the electronic records management process.

This paper presents a secure and DoS-resistant fragment authentication technique for Content-Centric Networking (CCN). Our approach not only guarantees the authenticity of each fragment, but also provides a high resistance to DoS attacks through the immediate verification of fragment authenticity at interim nodes on the routing path. Our experimental results demonstrate that the proposed approach provides much stronger security than the existing approach, without imposing a significant overhead.

Homomorphic MAC is a cryptographic primitive which protects authenticity of data, while allowing homomorphic evaluation of such protected data. In this paper, we present a new homomorphic MAC, which is based on integers, relying only on the existence of secure PRFs, and having efficiency comparable to the practical Catalano-Fiore homomorphic MAC. Our scheme is unforgeable even when MAC verification queries are allowed to the adversary, and we achieve this by showing strong unforgeability of our scheme.

This study conducted a comparative study using Korean and Chinese consumer data to confirm the impact of K-beauty brand's CSR motivation on CSR authenticity and brand trust, and the effect of CSR authenticity and brand trust on brand support. Of the collected data, 392 copies were used for verification and analyzed using a two-step approach and maximum likelihood measure. As a result of the study, it was found that value-driven, stakeholder-driven, and strategic motivations, excluding egoistic motivations, had a positive effect on CSR authenticity and brand trust. In addition, CSR authenticity had a positive effect on brand trust, which was found to support the brand. As a result of comparing Korean and Chinese consumers, it was found that CSR motives in both countries affect authenticity and brand trust, but Chinese consumers showed higher results in more areas than Korean consumers. These results show that K-beauty brands in order to expand the Chinese market, it has implications that it is necessary to understand Chinese consumers and strengthen the CSR motivation strategy they pursue.

As a cornerstone of the next generation air traffic management (ATM), automatic dependent surveillance-broadcast (ADS-B) system can provide continual broadcast of aircraft position, identity, velocity and other messages over unencrypted data links to generate a common situational awareness picture for ATM. However, since ADS-B messages are unauthenticated, it is easy to insert fake aircrafts into the system via spoofing or insertion of false messages. Unfortunately, the authentication for ADS-B messages has not yet been well studied. In this paper, we propose an efficient broadcast authentication scheme with batch verification for ADS-B messages which employs an identity-based signature (IBS). Security analysis indicates that our scheme can achieve integrity and authenticity of ADS-B messages, batch verification, and resilience to key leakage. Performance evaluation demonstrates that our scheme is computationally efficient for the typical avionics devices with limited resources, and it has low communication overhead well suitable for low-bandwidth ADS-B data link.

In this paper, to verify the authenticity of UxNB that assists terrestrial base stations, the solutions for SI (System Information) security presented in 3GPP TR 33.809 are analyzed from the perspective of UxNB. According to the definition of 3GPP (Third Generation Partnership Project), UxNB is a base station mounted on a UAV (Unmanned Aerial Vehicle), is carried in the air by the UAV, and is a radio access node that provides a connection to the UE (User Equipment). Such solutions for SI security can be classified into hash based, MAC (Message Authentication Codes) based, and digital signature based, and a representative solution for each category is introduced one by one. From the perspective of verifying the authenticity of UxNB for each solution, we compare and analyze the solutions in terms of provisioning information and update, security information leakage of UxNB, and additionally required amount of computation and transmission. As a result of the analysis, the solution for verifying the authenticity of the UxNB should minimize the secret information to be stored in the UxNB, be stored in a secure place, and apply encryption when it is updated over the air. In addition, due to the properties of the low computing power of UxNB and the lack of power, it is necessary to minimize the amount of computation and transmission.
