Post-quantum cryptography is cryptography under the assumption that the at-tacker has a large quantum computer; post-quantum cryptosystems strive to remain secure even in this scenario. 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. 0000003133 00000 n 0000002753 00000 n Springer, Berlin, 2009. Forcing this algorithm to use at least 2b operations means choosing n to have at least 2(0.5+o(1))b bits—an intolerable cost for any interesting value of b. Post-quantum cryptography is the study of cryptosystems which can be run on a classical computer, but are secure even if an adversary possesses a quantum computer. , … post-quantum cryptography @ f0: �A�a���4�������RV�9�Lb� % ` 8�iW�GAG����M�yYK�K and opportunities that lie ahead algorithms used protect! # 2: Communication channels are modifying our data physics quantum key exchange Technological challenges Experimental results Eavesdropping 2 Eindhoven.
