Digital Transformation, PKI and Shor’s algorithm

Everyone talks about digital transformation.  Almost none of them is aware that in 5 years quantum computers will probably have the potential for breaking private keys used for digital signatures.

The problem is that digital transformation relies on PKI cryptography mechanism. What will happen when someone rewrite and change original digital document and sign it again with original private key? Non-repudiation will not exist anymore.

In that time we will probably use another cryptography algorithms (quantum criptography), but for all older documents that were signed with PKI the authenticity will be repudiated.
