    摘要: A method of checking revocation of a device and software, and transmitting data to a secure device and secure software whose keys have not been leaked is provided. The method includes receiving authentication information of a device requesting transmission of data, and authentication information of software accessing the data in the device; checking revocation of the device and the software, based on the received authentication information; and transmitting the data to the software of the device, when the device and the software are not revoked as a result of the checking. By doing so, during transmission of data, such as content or a license, it is possible to check security of a device and software being executed in the device, so that the data can be more safely transmitted.

    摘要: Provided are a method and apparatus for encrypting and transmitting contents and decrypting the encrypted contents in order to improve security for authority of use of the contents in a contents used environment by installing various content protection software in a content device. The method of encrypting and transmitting the contents includes: receiving contents to be transmitted; encrypting the contents using a content key which is an encryption key according to the received contents; encrypting the content key using an external device key of an external device which is permitted to receive the encrypted contents to be used and a software key of a software program which is executed in the external device and permitted to decrypt the encrypted contents; and transmitting the encrypted contents and the encrypted content key to the external device. Therefore, security for authority of use of the contents, and more particularly, security for the content key are improved so that illegal distribution of the contents can be prevented.

    摘要: Provided is a method of key agreement between devices. Using the method, two devices on a network can exchange information using polynomials of a polynomial ring, authenticate each other using the exchanged information, and generate a shared key. Accordingly, an authenticated key agreement protocol, which has better security and a faster processing speed than a conventional encoding system, can be realized.
