ABSTRACT:
An operating encryption algorithm is converted to another encryption algorithm. When different encryption algorithms are operated by a personal computer100for use by a group A and a personal computer200for use by group B, an encryption algorithm, operated by the personal computer100is encrypted by the personal computer100with the encryption algorithm operated by the personal computer200and transmitted to the personal computer200.
