State of Symmetric & Hash Algorithms after Quantum Computing

The recent trends in information technology and communications have emerged as one of the main technological pillars of the modern age. The importance of cryptography has gained importance due to the requirement of security services (confidentiality, integrity, authenticity, and non-repudiation) in data storage/transmission. Quantum computing, first introduced as a concept in 1982, has now become a nightmare for the currently deployed cryptographic mechanism. Extensive research has been done on quantum platforms to resolve complex mathematical problems, which are intractable for traditional computing platforms. The formalization of such quantum computing platforms poses serious threats to the cryptographic algorithms. This article informs the reader about the implications/repercussions of quantum computing on the present cryptography in detail.

How HSMs support secure multi-tenancy?

 As business grew, so did the threat of compromise or theft of data.  To address these risks, both software methods and hardware devices were produced to secure networks, systems and data.  HSMs are dedicated devices, incorporated with both logical and physical protection mechanisms, designed to provide separate, secure operating environments where confidential or sensitive information could be treated without risk of exposure.

NIST shortlisted 26 algorithms for focal post-quantum research - get all the details here

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.

What is crypto-agility and how to achieve it?

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.

What are the common criteria for hardware security modules (HSMs)?

All the critical banking and payment systems incorporate Hardware Security Modules (HSMs) for the protection of user information and business transactions. HSMs deliver secure management of crypto keys along with encryption/decryption, digital signatures and authentication mechanisms which are frequently used for the security of corporate business applications.
