Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.

依据所选取的m序列优选对生成所有Gold序列族，确定产生Gold序列族的数量，标出每个Gold序列族中的所有序列，并实例验证（选取3个就可）族内序列彼此的自相关和互相关特性；在每个Gold序列族内，明确标出平衡序列和非平衡序列，并验证其分布关系。 (Race all the sequences in the Gold series, and example (choose three) within the family of autocorrelation and cross-correlation properties of sequences of each other Within each family of Gold sequence, marked clearly equilibrium and non-equilibrium sequences, and verify its distribution relationship )
