COMMUNICATION DATA TEXT MIXING ENCODING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/100386
Kind Code:
A1
Abstract:
Provided is a communication data text mixing/encoding method that prevents an attacker attempting to impersonate a sender from impersonating the sender. In S101, plain text is converted to communication data original text after OTID is added thereto. The communication data original text is mixed on the basis of a first mixing random number value in S102, S103 and S104. In S105, the mixed communication data original text is converted to communication data first converted text after the first mixing random number value is added to the end thereof. In steps S106 and S107, the communication data first converted text is subjected to a roll-shift computation for the entirety thereof by only a shift amount prescribed on the basis of a second mixing random number value, and in S107, is converted to communication data second converted text after the second mixing random number value is added to the end thereof. In S108, the communication data second converted text is encoded and converted to communication data text.
