Abstract

We aimed to analyze the natural population characteristics and habitat growth conditions of the valuable seaweed Silvetia siliquosa. Its population characteristics and habitat conditions were assessed monthly from May 2022 to April 2023 and April to August 2022, respectively, on selected habitats. The average population density, coverage, and frequency of S. siliquosa were 579 ± 94.18 ind./m2, 27.82 ± 6.92%/m2, and 78.37 ± 5.98/m2, respectively. The average thallus length and width were 47.53 ± 4.35 and 46.33 ± 4.17 mm, respectively, while the branch width, thickness, and frequency were 2.35 ± 0.03 mm, 0.59 ± 0.12 mm, and 2.8 ± 0.2 times, with a receptacle length and width of 24.13 ± 2.07 and 2.81 ± 0.19 mm, respectively. Among the 40 previously known natural habitats of S. siliquosa, growth was confirmed only in Sepo, Sebang, and Bangpo. The causes for the declining S. siliquosa populations could be attributed to habitat changes due to construction, coastal road maintenance projects, habitat disturbances, and increased pollutants. Habitat substrate disturbances and changes were the main causes of the decrease in S. siliquosa growth. Studies on environmental factors and habitat degradation, growth related to environmental factors, mass cultivation, and the marine ecosystem restoration of S. siliquosa are needed.

35. HRP: A HMAC-based RFID mutual authentication protocol using PUF.

Author

Jung, Seung Wook and Jung, Souhwan

Abstract

RFID is one of the promising automatic identification systems. However, RFID is vulnerable to various threats such as tracking ID, cloning attack, spoofing attack, etc. Some mutual authentication protocols utilize cryptographic functions such as hash, but retrieving efficiency is very low. A naïve challenge-response protocols based on PUF which is innovative circuit primitives require maintaining huge challenge-response pairs. Some lightweight protocols based on PUF have been reported to be broken. This paper proposes a HMAC-based mutual authentication protocol using PUF for RFID to address the problems of previous protocols as above mentioned. The proposed protocol provides robust security properties as well as efficient enough for the active tags in terms of the computation. [ABSTRACT FROM PUBLISHER]
