CODE-BASED ENCRYPTION APPARATUS AND METHOD CAPABLE OF PREVENTING REPLAY ATTACK

摘要

A code-based encryption apparatus and method capable of preventing a replay attack are disclosed. A code-based encryption apparatus and method capable of preventing a replay attack according to the present invention is characterized in that in a code-based encryption scheme, a predetermined random number is generated every time encryption is performed and the random number is reflected in the original message, It is possible to minimize the exposure of the original message due to the replay attack of the third party by inducing the pattern to be generated differently.
