Differences between Classical and Quantum Cryptography
As we know that Cryptography comprises of two processes which are namely as encryption and decryption performed at sender and receiver end respectively. Basically Cryptography is practiced or implemented for doing secure communication between sender and receiver in the public environment in such a manner that other than these two parties no one could get or understand the message that is delivered.
On the basis of type of encryption and decryption of the message we can distinguish between Classical and Quantum Cryptography as follows −
| Sr. No. | Key | Classical Cryptography | Quantum Cryptography |
|---|---|---|---|
| 1 | Basis | In Classical Cryptography encryption and decryption is done on the basis of mathematical computation. | On other hand in Quantum Cryptography encryption and decryption is done on the basis of quantum mechanics. |
| 2 | Complexity | As Classical Cryptography is based on mathematical computation so is less complex and is widely used. | On other hand Quantum Cryptography is based on physics so is more sophisticated. |
| 3 | Signature | Classical Cryptography has Digital Signature. | On other hand Quantum Cryptography does not have Digital Signature. |
| 4 | Bit storage | Classical Cryptography has bit storage of two n-bit strings. | On other hand Quantum Cryptography has bit storage of one n-bit strings |
| 5 | Range | Communication range is millions of miles in case of Classical Cryptography. | On other hand Communication range is maximum 10 miles in case of Quantum Cryptography. |
