Abstract

A significant portion of the new advancement in lattice-based cryptography will be covered in this comprehensive study. There is sufficient research work proving to be conclusive regarding the strength of lattice-based cryptography. Even in adverse security design scenarios, the degree of security provided by the lattice-based encryption proves to have a fair chance to be considered for critical applications. With more and more modern-day transactions demanding secure nature in business aspects, the current cryptographical systems are becoming expensive to maintain and not providing absolute security or privacy against technologically adept adversaries. Hence the need has come to design more robust secure system. This is forcing the security designers to work in the exciting area of lattice-based cryptography with computationally complex mathematical strategies. These are complex systems which will instill trust of highest degree in current scenario where the malicious attackers will try to use quantum computing in their highest ability to break the security of the encryption systems. Cryptography with lattice-based systems is based on techniques with lower computational complexities which have paved the way for research directions in homomorphic encryption. With the use of public key cryptography becoming expensive day by day for maintenance purposes, the advent of lattice-based cryptography is inevitable. Due to the threats arising during poor system design of cryptosystem, the need of lattice-based cryptosystems are increasing every year. Many organisations are thinking to move their security paradigm towards a more computationally complex encryption system. For provably worst-case hardness of security problems, lattice-based principles can be more secure, and they can act as versatile objects for powerful cryptographic frameworks.
