Abstract: Disclosed are an online wallet device and a method of generating and verifying the same. The online wallet device includes a first memory in which a key is stored, a second memory for storing an agent-bitstream including at least one agent that accesses the key stored in the first memory or performs a key-related operation, and an FPGA chip on which at least one agent is installed through loading of the agent-bitstream.

Abstract: The present invention relates to a method for protecting content of an electronic device, comprising the steps of: enabling a first security module to transmit a data encryption request to a second security module when data requiring security is generated according to the execution of a security application by the first security module in a security storage region of a memory; enabling the second security module to generate an encryption key by using the authentication information included in the data encryption request and to encrypt the data included in the data encryption request by using the encryption key; enabling the second security module to transfer the encrypted data to the first security module; and enabling the first security module to store the encrypted data in the security application.

Abstract: Provided is a modulo scheduling method. The modulo scheduling method includes conducting a search, based on a data dependency graph of a loop, for a recurrence in which a sum of iteration distances between command nodes is less than a predetermined critical value; and determining a processing order of the recurrence.

Abstract: A snoop-based kernel integrity monitoring apparatus and a method thereof are provided. More particularly, provided are a kernel integrity monitoring apparatus which is provided as a hardware device independent of a host system, and snoops traffic occurring in a system bus of the host system and by detecting a write attempt in a kernel immutable region, monitors integrity of the kernel, and a method thereof. According to the apparatus and method, by analyzing traffic of the system bus of the host system, a write attempt in the kernel immutable region is detected. Thus, a transient attack which is difficult for a snapshot method to detect can be detected.

Abstract: A method to transfer a plurality of data stored in a memory using one instruction. In a memory including at least two regions to which the addresses are assigned respectively, data are allocated to the addresses in sequence, and the allocated data are transferred using one instruction. At least one block is generated, which transfers data using one instruction, and it is instructed to include the data in the at least one block. The data in the block are linked with each other, and the number of paths linking two data is calculated with respect to the at least one block. The data are linked using shortest paths in consideration of the number of the linking paths, and the data are allocated by the addresses using the shortest paths.
