Abstract:
1. A diffused symmetric encryption/decryption method using a first computer and a second computer with asymmetric keys, wherein said method operates pursuant to the mathematical architecture of diffusion algebra, comprising steps of: i. selecting a matched pair of a public key and a private key, wherein said matched public key and private key are a numeric value S, wherein S indicates a one-dimensional binary matrix having n>0 positions, and position labels are from 0 to n−1; in addition, S comprises at least one various element e ii. if the multiplication of said matched public key and private key is equal to e iii. using the first computer to multiply said public or said private key with a plaintext to generate a ciphertext, wherein the plaintext is a numeric value S; and iv. using the second computer to obtain said plaintext by multiplying said private key or said public key with said ciphertext.
