There is a significant uncertainty when it comes to the impact of quantum computing on modern cryptography. Perhaps the largest concern centers on just exactly when the quantum cryptography apocalypse will occur. While there are flurries of activity surrounding both the development of stable quantum computers and the cryptography algorithms that can withstand them, many are operating on what is at best a "loose" timeline. To help you on your journey to crypto-agility, let's take a look into how to determine your timeline for post-quantum preparation.

Post-quantum cryptography has a strong impact on Entrust Datacard's main business areas: 
on SSL, PKI, as well as on the authentication business.

It has taken over two decades to establish and secure the current e-commerce applications. The security of most of these systems principally relies on cryptographic algorithms which have served the purpose till now. Since the initiation and evolution of quantum computing, some cryptographic algorithms have threats. To mitigate the security gap, numerous post-quantum algorithms have been proposed. This article enlightens the journey towards post-quantum algorithms and security parameters of the newly proposed post-quantum algorithms.

In this video blog, Madjid Nakhjiri, Senior Principal Security Architect at the Samsung Strategy and Innovation Center, describes his company’s strategy to develop products today which are prepared for the post quantum era.

With every passing day, the need for crypto agility becomes more important. Whether you believe quantum computing is 10 years, 20 years or more away, the inevitability is that it is approaching fast. This is why many leading technology organizations have begun to research the impact of new quantum-safe algorithms on their existing products or infrastructure. This research is facilitated by the use of , Hardware Security Modules (HSMs). It is within the secure parameter of an HSM that existing and quantum-safe algorithms should be executed - but not many HSMs are capable of doing this. This why the flexibility and functionality of HSMs play an important role in in crypto agility.

Quantum computing will decimate the security infrastructure of the digital economy. Quantum computing in general is certainly a blessing to humanity in many respects and it promises to disrupt evolution of technology in more than one dimensions. But it is also a curse to security, as cryptographic algorithms that proved to be secure for decade may be breached by quantum computers within minutes.

Cryptography is one of the cornerstones of all blockchain infrastructures. Hashes link blocks together and public-private key cryptography helps secure data and verify transactions. A major advantage of blockchain is that its cryptography man es it virtually untamperable, with changes in the crypto being virtually impossible.

Quantum computers will revolutionize many industries and will be powerful enough to break all commonly used public key cryptographic algorithms.

Crypto-agility can be elaborated as the ability and aptitude of a system to promptly shift from the existing cryptographic algorithms and primitives to the newer and updated ones. With the advent of quantum computing, it has been obvious that the RSA based public-key systems which stand on large integer factorization and discrete logarithm problems would be breakable.
