Abstract: Modern Cryptography is based on computationallysecure
algorithms. With the emergence of quantum computers,
it is possible to crack the heritage computationally-secure
algorithms. Quantum Cryptography/ Quantum Key Distribution
is a new and evolving field for secure communication. It is able
to detect eavesdropping in a failsafe manner as it is impossible to
copy the data encoded in a quantum state without changing its
state. This paper discusses the types of modern cryptography,
limitations of their use in practical applications, quantum safeencryption
schemes that overcome the challenges associated
with the modern cryptography, and various aspects of one of the
safe encryption schemes i.e. quantum cryptography. This paper
focuses on discussing the work done in the field of quantum
cryptography such as line-based and space-based experiments
and the challenges associated with its practical implementation.
Impact of satellite orbit is also addressed, recommending a
preferred scheme for a global network based on the quantum
approach. This paper also provides a detailed discussion of
various quantum cryptography protocols.
