What is Quantum Cryptography and How Will it Help the Future of Security? Part 2
In our previous blog, we introduced the future of cyber-security and the vulnerabilities that exist for companies and their current encryption software. One important security measure that should be implemented is Quantum Key Distribution (QKD), which works towards detecting hackers.
The Rise of Quantum Cryptography and How can we be part of the Resistance
The encryption that we use today has been beneficial for years, but it is quickly becoming archaic and useless. The cryptographic services that we use today use one key to change the message or the data and a second key to decode the information when it reaches the receiver. The reason that this technology is becoming less effective is that our current computers are not fast enough at what they are doing.
For ordinary computers to be able to break the code, it would take years, which means that this encrypted data is safe. Our current computers are not going to be in any danger of data being hacked if it has been adequately encrypted, which means that the data is safe. With new quantum computers, the process to break the code and access the information is much shorter, which means that all the data that we thought was safe can be obtained with new quantum computers quite easily risking public safety.
New quantum technology is going to help users to protect sensitive data better that they want to keep hidden and is going to help make sure that the data we thought was safe is just that. These new computers and QKD technology are working to help make sure that the data we are sending is actually secure and that others cannot access it without our permission.
QKD technology is not all that advanced right now; currently, it can only send information down a tiny cable before it becomes too dim to be received. Researchers hope to help strengthen the signal to the point that it can be easily used for long-range transmissions and as a means of really sending information that is truly protected.
Current crypto is very weak against quantum crypto; however, there are new algorithms that are being developed that are resistant to it. With the vast amount of data collection and sensitive information stored across all industries, which include Government and private companies, businesses need to place the security of their data at the forefront.
A few solutions that should be considered include Homomorphic encryption and lattice-based cryptography.
Lattice-based cryptography serves as a general term for constructions of cryptographic primitives that include lattices within the security proof or in the development itself. One of the most significant uses of lattice-based constructions is for post-quantum cryptography. Lattice-based constructions display the ability to be resistant to attacks against quantum and classical computers. This offers a significant layer of protected compared to public-key schemes, which are easily attacked by a quantum computer.
Homomorphic encryption is another form of encryption which is used for privacy-preserving outsourced storage and computation. Homomorphic encryption is a method that performs calculations on encrypted information without decryption first, leaving it more secure against hackers.
