  • ENCRYPTION METHOD BASED ON HIGH-DIMENSIONAL INTERATIVE FUNCTIONS
    Publication number: 20260254618
    Abstract: The present disclosure discloses an encryption method based on high-dimensional iterative functions, belonging to the technical field of data encryption. The system comprises the following steps: s1: establishing calculation parameters, determining plaintext space p, ciphertext space C, and a private key sk through calculation parameters, s2: constructing an iterative function system, and obtaining a corresponding public key pk; s3: for plaintext w and ciphertext c, converting plaintext w to be encrypted into plaintext space C for encryption and decryption. The present disclosure adopts the method to construct an IFS different from previous forms, and constructing an encryption system based on a two-dimensional IFS. In addition, the present disclosure improves randomness in selecting encryption parameters, and due to the design of trapdoor functions, an existence of nonlinearity enhances a security of the encryption system.

  • USE OF PROTEIN NOG1 IN REGULATION OF PLANT YIELD AND GRAIN NUMBER PER EAR
    Publication number: 20210079414
    Abstract: Protein nog1 is used in the regulation of plant yield and/or grain number. The transgenic treated Guichao 2 in which the expression of the protein nog1 is inhibited has a reduced yield per plant and/or a reduced grain number of the main stem as compared with untreated Guichao 2. The transgenic plant obtained by introducing a nucleic acid molecule encoding the protein nog1 into SIL176 has an increased yield per plant and/or an increased grain number of the main stem as compared with untransformed SIL176.
