| titleOfInvention | Public key encryption device |
| abstract | To realize an encryption method using a number sequence that is a public key of knapsack encryption as a complete random number sequence. SOLUTION: For I (I ≧ 3) private keys ei-1, I private keys Pi (ei-1 and Pi are relatively prime), a number n representing the dimension of a vector, and modulus Z In the public key memory, there are I dimensional public key vectors ai whose components are 0 or more and less than Pi and n dimensional public key vectors bj whose components are 0 or more and less than Z (J is 2 or more). Remember. A random number generator and an arithmetic unit generate I-dimensional random number vectors ri whose components are 0 or more and less than Z and n-dimensional J random number plaintext vectors vj whose components are 0 or more and less than Z. The checker checks whether m≡Σj = 1... Jbj · vj (modZ) is established for plaintext m. If not, random number vector ri and random plaintext vector vj are regenerated. The operation unit generates I ciphertexts Ci having Ci = ai · ri. [Selection] Figure 1 |
