Cryptography has been useful in many applications such as transactions, computer or mobile passwords, internet connectivity, e-commerce transactions etc. Most of the applications use RSA algorithm for digital signature (dongle based or eSign) or digital certificate (issued by a certified authority). RSA strength is based on the fact that it is difficult to factorize a large integer. With the improvements in the quantum computers, classical cryptography is under the threat of quantum attacks. Quantum computers can factorize the large modulus with the help of Shor's algorithm in much shorter time. This paper provides literature survey of Crystals Dilithium Algorithm which is one of the post quantum digital signature schemes that has reached the final round of NIST competition for post quantum cryptography and its use case in online digital signing facility, eSign.
