Attacker just need to create about a 10^6 keys (19 bit security strength) to get pair with the same digit code. Thank you for your response. Post it as an answer when you have time. | |
| Mar 4, 2020 at 11:52 | comment | added | SEJPM | The technical term you are looking for is short authenticated string (SAS) which was originally introduced by Vaudenay at Crypto 2005 (PDF). The linked paper discusses long-message authentication using SAS, one could reasonably use that to authenticate two public keys. | |
