Analyzing Requirements for Post Quantum Secure Machine Readable Travel Documents

Abstract

In a post-quantum world, the security of digital signatures and key agreements mechanisms used for Machine Readable Travel Documents (MRTDs) will be threatened by Shor’s algorithm. Due to the long validity period of MRTDs, upgrading travel documents with practical mechanisms which are resilient to attacks using quantum computers is an urgent issue. In this paper, we analyze potential quantum-resistant replacements that are suitable for those protocols and the ressource-constrained environment of embedded security chips.
