Not taught in schools! An introduction to cryptographic communication and cryptographic techniques for copyright protection in a column.
This time, let's talk about the technology that determines whether the data itself has been forged or tampered with. In addition to using public key cryptography to prove that "this is indeed a document written by the person," there is another method called a message digest.

This includes scrambling in paid broadcasts and copy protection technologies for digital terrestrial television. This might actually be more familiar to us. *For more details on the column, you can view it through the related links. Please feel free to contact us for more information.*
