  • Based on the teleportation by quantum walk, a quantum secret sharing scheme with credible authentication is proposed. Using the Hash function and quantum local operation, combined with the two-step quantum walks circuit on the line, the identity authentication and the teleportation of the secret information in distribution phase are realized. Participants collaborate honestly to recover secret information based on particle measurement results, preventing untrusted agents and external attacks from obtaining useful information. Due to the application of quantum walk, the sender does not need to prepare the necessary entangled state in advance, simply encodes the information to be sent in the coin state, and applies the conditional shift operator between the coin space and the position space to produce the entangled state necessary for quantum teleportation. Security analysis shows that the protocol can effectively resist intercept/resend attacks, entanglement attacks, participant attacks, and impersonation attacks. In addition, the quantum walk circuit used has been implemented in many different physical systems and experiments, so this quantum secret sharing scheme may be achievable in the future.

  • Korea's ancestral culture has limited travel and contact due to Corona (COVID-19). In addition, Korean ancestral culture meets in person to commemorate the deceased. In this paper, we propose a non-face-to-face metaverse memorial platform service that can commemorate the deceased and perform ancestral rites in the cyber world (virtual reality) by applying the metaverse technology. The services proposed in the study consisted of a remembrance hall that displays the life story of the deceased, a ancestral hall that conducts ancestral rites for the deceased, and a deceased pavilion that checks the remains and wills of the deceased. In addition, the virtual reality device (HMD: Head Mounted Display) set the teleportation and content resolution to 4K to minimize dizziness. In particular, the priests applied interaction technology to provide an immersive service for ancestral rites between family members. The researched memorial hall metaverse service is a metaverse-based platform service that allows anyone to commemorate the deceased as a family unit in a non-face-to-face state rather than face-to-face.

From the Shintong of the Buddha to the Shini of Eminent Monks (붓다의 신통에서 고승의 신이로)

  • In Buddhism, there are specific terms related to miracles and miraculous acts such as the Sanskrit term, abhijñā, which was translated as into Chinese characters as shintong (神通). This term implies the six supranormal powers. It originally meant 'direct knowledge,' 'high knowledge,' or 'knowledge beyond the common senses,' which was understood as a superhuman and transcendental ability possessed by Buddhas, Bodhisattvas, and noblemen. However, this took on different meanings and morphed into different terms later in India and China. This article analyzes the subject, object, type, and purpose of these shintong, focusing on the Sutra for the Householder Kaivarti (堅固經, Gyeonggo-gyeong, Kaivarti-sūtra) from the Longer Discourses (長阿含經, Jang-Ahamgyeong, Dīrghâgama) and exemplary Buddhist texts such as the Sanskrit, In Praise of the Acts of the Buddha (佛所行讚, Bulsohaengchan, Buddhacaritam) and the Chinese Records of Eminent Monks (高僧傳, goseungjeon) and Continued Records of Eminent Monks (續高僧傳, Sok-goseungjeon). The historical evolution and changes to the meaning of Shintong in Indian and Chinese contexts can be observed through these texts. In the Sutra for the Householder Kaivarti, the Buddha said that there are three kinds of Shintong: supranormal footedness (神足, shinjok, ṛddhi-pāda), mindreading (觀察他心, gwanchaltashim, anya-mano-jñāna), and education (敎誡, gyogye, anuśāsana). Among them, supranormal footedness (multiplying one's body, teleportation, flying, walking on water, etc.) and mindreading were denied because, at that time, claims of this nature were used to appeal to people's emotions and inspire sincerity, but this was of no use in conveying the Buddha's teaching. On the other hand, education, acquired only with through enlightenment, was sanctioned as a shintong unique to Buddhism. However, in In Praise of the Acts of the Buddha, supranormal footedness and mindreading were described as important ways to lead people to enlightenment, while education pertained to the whole of spiritual work. In China, Buddhism was a foreign religion at first, and it urgently sought to be accepted. After the increase of its religious influence, introspection on discipline and practice was meant to firmly deepen its roots. In line with this, shintong and miracles were transformed and expanded to suit the Chinese cultural context. Such changes in Buddhist history are well illustrated by the shini (神異, miraculous powers) described in Records of Eminent Monks and the gamtong (感通, penetration of sensitivity) detailed in Continued Records of Eminent Monks. In Records of Eminent Monks, the subject of shini was that of eminent monks and its objects were those who did not know of Buddhism or believe in it. In Continued Records of Eminent Monks, however, the monks themselves could be objects of shini. The change of object suggests that the purpose had shifted from edification to awareness and self-reflection. Shini focused on edification, whereas gamtong re-emphasized the importance of the pure discipline and practice of monks during the 6th and 7th centuries when China became predominantly Buddhist.
