A Study on a Secure USB Mechanism That Prevents the Exposure of Authentication Information for Smart Human Care Services

“…As described above, secure USB flash drives are classified into the hardware and software types. The hardware type of method uses a hardware module that provides an additional security function, such as user authentication or data encryption/decryption, while the software type of method uses the special software provided by the manufacturer as an additional security function, such as access control [5]. Each type is further classified in detail, as shown in Table 1. 2.2.1.…”

“…The controller-internal password method provides 3 Journal of Sensors user authentication by adding a function to set the password in the controller and protects the data by only allowing authenticated users to access the data. With the user authentication technology, the users register the password and are allowed to access internally stored data only when the password input during authentication matches the registered password [5]. The partitioning method divides the secure USB flash drive into partitions to add domains that provide the security function and control access through them.…”

“…There are many studies on diverse methods of applying these technologies to protect data, which can be broadly divided into the software type and the hardware type. The software type refers to methods of protecting internal data using only software and includes the data encryption/decryption method and the access control method [5]. The data encryption/decryption method uses a mathematical tool to encode and decode the data to prevent the inference of plain text, in order to solve the problem of data being stored in plain text in a conventional USB flash drive.…”

“…Unlike the data encryption/decryption method, the access control method uses user authentication to block access by unauthorized users and allow access only by authorized users to the disk itself, image, or file used as a disk. Access control methods include access control [2] through user authentication [5] and access control by device authentication. On the other hand, the hardware method safely protects data using a separate hardware module.…”

“…On the other hand, the hardware method safely protects data using a separate hardware module. The main methods of protecting data include the method which uses an encryption module and the method which uses a flash drive controller [5]. The method using an encryption module uses a dedicated hardware security module to make it difficult to access secret information using reverse engineering, which is the fundamental problem of the software method.…”
