Problems solved by technology

[0012] The present invention is proposed in order to solve the existing problems of this type. The purpose of the present invention is that the dynamic password card connected to the user terminal not only stores the encryption key, but also encrypts the file, thereby preventing the dynamic password from being leaked by hackers. Only when the dynamic password card is connected to the user terminal, the cloud file will be decrypted, and synchronization can be realized, therefore, the security is further improved

Abstract

Disclosed is a security key device for cloud services. The security key device includes an interface unit that provides an interface with the user terminal, a storage unit that stores an encrypted user file, and an encryption / decryption conversion support controller that encrypts, when a file to be uploaded to a cloud server is received from the user terminal, the received file and stores the encrypted file in the storage unit to transmit the encrypted file to the user terminal, and stores, when an encrypted file downloaded from the cloud server is received from the user terminal, the received encrypted file in the storage unit and decrypts the encrypted file to transmit the decrypted file to the user terminal. Even when a cloud server is hacked, individual and company's important data cannot be opened, encryption / decryption is processed in a hardware encryption accelerator, and therefore it is possible to prevent leakage of an encryption key even when a personal PC is hacked, thereby significantly improving security compared to the related art.

Description

technical field [0001] The present invention relates to a dynamic password card for providing cloud services with enhanced security protection and a system and operation method using the same. The hardware dynamic password card detachably connected to the user terminal manages the encryption key, and the encryption engine is also in the The hardware embedded device decrypts the file and stores it in the cloud server, thereby strengthening the technology of security protection. Background technique [0002] Recently, cloud computing environments are widely used for efficient allocation of IT resources and secure storage of data. The concept of cloud computing was proposed by American computer scholar John McCarthy as early as 1960. Recently, with the rapid development of communication facilities, the requirements for effective distribution of computing environments are increasing, and the speed of development and development is also accelerating. [0003] In the cloud comput...
