An apparatus automatically inspects security of mobile applications. The apparatus includes a static analyzer to perform a static analysis by reversing an execution file of the mobile application, and an automatic execution processor to generate an automatic execution script used to automatically execute the execution file and execute the automatic execution script automatically to generate a log. The apparatus further includes a dynamic analyzer to analyze whether a pattern of malicious codes was executed in the execution file using the result of the static analysis and the log resulted from the automatic execution.

The present invention relates to a method of searching data for a plurality of keywords when a user encrypts the data and stores the encrypted data in an unsecured server. The user transmits the inner product value of a search keyword set to a sever, and the server compares the received inner product value to an inner product value of a stored index set. When a document for which the two inner product values are matched with each other, the server returns the document.
摘要:
An apparatus for generating a secret key generates the secret key by using information of a mobile RFID terminal, transmits the generated secret key to an RFID tag attached on an article, and decrypts a unique item identifier of the article encrypted by using the generated secret key after receiving the unique item identifier of the article encrypted by using the secret key from the RFID tag. By this configuration, it is possible to protect user's personal privacy of the mobile RFID terminal in a state where user's intervention is minimized.

Provided is an RFID tag. When no external pressure is applied to a packaging structure, a wire for transmitting power and data from an antenna is separated from an RFID chip by an air layer. When external pressure is applied to the packaging structure, the wire is connected to the RFID chip to transmit the power and data between the antenna and the RFID chip.

摘要:
A server provides the user's desired data without the server knowing the contents or keywords of data by using a method of searching the desired data without decrypting the encrypted data, such that the privacy for the important data of the user can be secured. Also, the present invention shortens the operation time when searching the encrypted data, such that it can prevent the degradation in efficiency due to excess operation involved in the previous existing methods based on the pairing operation.
