The invention relates to a security-enhanced authorizing and authenticating method of mobile application. The security-enhanced authorizing and authenticating method of the mobile application, disclosed by the invention, comprises the following steps: registering, and acquiring basic information of the mobile application by a publishing system; pre-authorizing, generating a pre-authorizing code of the mobile application by utilizing the basic information, and embedding the pre-authorizing code in a mobile application program; performing enhanced publishing and authorizing, automatically detecting whether the pre-authorizing code and the basic information of the mobile application are correct or not by the publishing system, if so, automatically publishing, collecting practical feature information and a publishing code of the mobile application, and generating a security-enhanced authenticating code with the pre-authorizing code; reliably installing, acquiring the practical feature information, the pre-authorizing code and the publishing code of the mobile application while installing the mobile application so as to generate the security-enhanced authenticating code, and authenticating reliable installation; and reliably starting, in the event of starting the mobile application every time, detecting whether the pre-authorizing code is correct, and starting if the pre-authorizing code is correct. The invention provides a method for detecting the security reliability of the mobile application; and therefore, the problem that user information is stolen as the mobile application is maliciously tampered is effectively avoided.

The invention discloses a direct solar heat supply device of a curing barn and the curing barn with an auxiliary direct solar heat supply function. The direct solar heat supply device of the curing barn comprises light transmission plates, hollow light transmission heat-insulation layers, a solar heat collecting panel and a radiating component; the curing barn with the auxiliary direct solar heat supply function comprises a baking chamber of the curing barn, a heat supply chamber, a circulating fan and a plurality of direct solar heat supply devices of curing barns; and the direct solar heat supply devices of the curing barn are mounted on the top of the baking chamber of the curing barn and can directly replace a roof of the baking chamber of the curing barn to directly supply heat to the baking chamber of the curing barn. The direct solar heat supply device and the curing barn have the advantages that solar energy can be transmitted from the outside of the curing barn to the inside of the curing barn in a one-way manner by the aid of the direct solar heat supply device of the curing barn, the multiple direct solar heat supply devices of the curing barn are mounted on the top of the baking chamber of the curing barn, the thick roof which is commonly adopted for realizing a heat-insulation effect for a curing barn and is high in manufacturing cost is omitted, and effects of effectively and directly utilizing the solar energy and saving baking energy can be realized.

The invention belongs to the technical field of fingerprint recognition and encryption fusion in pattern recognition, and discloses an irreversible fingerprint template encryption method based on symmetric hash. The method of combining symmetric hash function with positive remainder function can strictly guarantee the irreversibility of hash operation. The security of the entire encryption algorithm is improved. Because the number of equations of the constructed hash function is less than the number of inputs, that is, the rank of the coefficient matrix of the non-homogeneous equations is equal to the rank of the augmented matrix, and is smaller than the number of equations, there are infinitely many equations in theory solution, so the input data information cannot be pushed back through the result. In addition, due to the characteristic that the output of the sine and cosine functions corresponds to infinitely many inputs, the irreversibility of the algorithm of the present invention is raised to a higher level. Even if an attacker steals the user's key and template, it cannot push back the user's original fingerprint. At the same time, in the process of hash operation, the method of combining user keys is simpler, more efficient, and more revocable.

The present application discloses a SIP security authentication method and system based on the learning problem with errors on the ring. The user client U encrypts the password PW to obtain the encrypted data PWE, and sends the user name ID, the encrypted data PWE and the verification key to the server S The server S receives the username ID and the encrypted data PWE sent by the user client U, encrypts the received data, and obtains the encrypted data VPW; U sends a verification request to S; S uses the verification key to process the encrypted data VPW, After obtaining the first verification message, the server sends the first verification message to U; after U receives the first verification message, the user client verifies the first verification message, and if the verification passes, the client returns the second verification message to the server S; the server S verifies the second verification message, and if the verification passes, the client U and the server S use a common session key to encrypt subsequent communication information.

The invention discloses a Hash fingerprint based on location information and DNA information, a construction method and application thereof. The Hash fingerprint of the present invention is obtained by collecting plant geographical location information and DNA feature coding information, digitally marking the feature information, and constructing a Hash fingerprint. The method described is to first store and encrypt the geographical location information of plants (acquired through the global satellite positioning system) and DNA information with a one-way Hash code (an irreversible mapping from plaintext to ciphertext). There is only encryption, no decryption, and a fixed-length output is obtained after changing the input of any length. The algorithm of the invention can extract the traceability characteristic information of the plant according to the difference of the position information of the plant and the DNA information, and carry out Hash fingerprint identification, and the identification rate is high.
