Digital signature method using RSA public-key cryptographic based on CRT and apparatus therefor

摘要

The present invention is digital using the RSA public key encryption scheme based on a secure CRT in error injection attack signature method and relates to the apparatus, specifically, an error in a part of the signature that is calculated by the RSA public key encryption scheme based on CRT occurs and so it can lead to calculation errors that can be injected by attackers to attack the secret to spread its errors throughout the signature, if applicable.
