Abstract

In the current time, the classical cryptographic systems are used worldwide. Cryptography makes the transmission operation secure and it ensure the basic motivation of security such that availability, integrity, confidentially and non-repudiation. The development of quantum computing algorithm such that Shor’s algorithm rise the threats towards the classical cryptographic infrastructure particularly in public key infrastructure i.e. RSA and ECC. Also, Grover’s algorithm provides the square root time enhancement of searching of keys in the symmetric key cryptography. In this scenario, the fully operation quantum computer will break the classical cryptographic systems, and it is the main reason behind the advancement of post quantum cryptography (PQC). Specially, in the IoT network, the energy constrain end devices have the main issue to implement the strong cryptographic methods to secure the network from quan-tum attacks. The current available cryptographic methods which are quantum resistance in context of IoT network is thoroughly discussed in the paper. Also, key families of PQC algorithms i.e. lattice-based, code-based, multivariate polynomial based, hash-based, and isogeny-based and the NIST standardization of PQC techniques are investigated. This survey will be work as a bridge between deployment of PQC and existing methods of PQC in context of IoT environment.
