16 Introduction on Post-Quantum cryptography @NIS Summer School, 26-28 September 2018. When we compare post-quantum cryptography with the currently used asymmetric algorithms, we find that post-quantum cryptography mostly have larger key and signature sizes and require more operations and memory. �ƌܛ�,`~�ീ�=�eK���u/7�h60�p�X��LZq��"C#)�y�C����`���NS}���x��{��SN�'�3�5�(�'��(j�� [!���jx�@��PS��MM��F�r��'Ҹ�i��pl>!��3��&SG�ɢ��I��\=7.>q���r�a�B�e�/ ��\����tQ��O�.������s^�c�$%����~ �B˓�ZE�f�,

Perhaps, after seeing quantum computers destroy RSA and DSA and ECDSA, Internet users will leap to the conclusion that cryptography is dead; that there is no hope of scrambling information to make it incomprehensible to, and unforgeable by, attackers; that securely storing and communicating information means using expensive physical shields to prevent attackers from seeing the information—for example, hiding USB sticks inside a locked briefcase chained to a trusted courier's wrist. some researchers provided the idea about post-quantum cryptography which refers to research on cryptographic primitives (usually public-key cryptosystems) that are not breaka‐ ble using quantum computers.

Recently, NIST initiated a process for standardizing post-quantum cryptography and is currently reviewing first-round submissions. This book introduces the reader to the next generation of cryptographic algorithms, the systems that resist quantum-computer attacks: in particular, post-quantum public-key encryption systems and post-quantum public-key signature systems. Abstract: Quantum cryptography (QC) provides a practical way – based on physics – to solve the key establishment problem with information-theoretic security against a quantum attacker. Post-quantum cryptography is centered around the algorithms that are designed to secure data in the age of quantum computing and beyond. 0000349038 00000 n
