Data security emerges as a significant function as we progressively locate ourselves within a networked society. Everyone’s details are secure thanks to encryption systems implemented to secure our letters and urgent financial transactions. But there’s a looming threat on the horizon: quantum computing. This piece of revolutionary technology places itself…
A Quantum computer is an advanced, super-powerful computer. They can solve complex problems and do many things that regular computers can’t. This technological advancement also creates new threats to today’s Information technologies. It can break cryptography algorithms in minutes or seconds, whereas regular computers take thousands of years. In 2019,…
Understanding how data travels from one point to another is crucial in computer networking. Sending an email, streaming a video, or browsing a website – all these actions involve a complex series of interactions between devices connected to a network. To make sense of this complexity, the OSI model is…
What is PKI? PKI is a set of technologies, policies, and procedures applied to establish, administer, issue, and terminate digital certificates and associated public-private key pairs. It provides a solid basis that allows assurance for safe digital information and communications in matters of authentication, encryption, and digital signature. PKI in…
NIST has made its most recent major step in securing digital communication from the new threats of quantum computing. It wrapped up the promotion of 14 cryptographic algorithms to the second round of its additional post-quantum digital signing competition. This is the agency’s additional step towards the persistent effort to…
Starting November 10, 2023, Azure announced that all connections to its services must use TLS 1.2 or newer versions for better security. The older versions, TLS 1.0 and TLS 1.1, are being phased out because newer versions offer better security features. What is TLS? Transport Layer Security is a protocol…
In its step further toward privacy and security, Apple recently announced an important update regarding the receipt signing intermediate certificate of the App Store, which will be able to switch over to the SHA-256 cryptographic algorithm. This changes the requirements for app validation as well as in-app purchases, and so…
What is E2EE? The most advanced barrier against leakage is end-to-end encryption, which is a security protocol used in communication systems to guarantee the confidentiality and authenticity of the transmitted data. Just as conventional encryption methods carry out data encryption and decryption in different places, E2EE encrypts messages on the…
In the digital era, where data transmissions are performed over networks, most of the information being processed is sensitive; thus, safeguarding data security and privacy is of utmost significance. One of the necessary household cybersecurity algorithms is RSA asymmetric encryption. Named for its architects Rivest, Shamir, and Adleman, RSA encryption…
Encrypted data is a security procedure that translates readable text into unreadable text by data encryption algorithms. In this procedure, the plaintext data, the name of the original data, is allocated by the key of encryption into an unreadable format. The outcome of that process looks like jumbled-up characters or…
The National Institute of Standards and Technology (NIST) has formally announced three new post-quantum cryptography (PQC) standards ML—KEM, ML-DSA, and SLH-DSA, on August 13, 2024, to strengthen cryptographic defenses against potential cyberattacks by quantum computers. With this significant accomplishment, cryptography enters a new age and establishes a solid basis for…
What is Two Way SSL? Two-way SSL, sometimes also referred to as mutual SSL authentication, is always a Secure Sockets Layer protocol that provides a strong security solution or a safe and encrypted channel for two parties, such as a client and server, to communicate. Unlike the TLS/SSL version, which…
Introduction SSH is a flagship technology of remote server access and safe data transfer software that runs across whole businesses and makes their data secure. SSH, through SSL, squeezes out the security points, even for remote connections. Recommended: What Is SSH (Secure Shell)? How does the SSH Protocol work? […
According to a report by PingSafe, 45% of data breaches occur on the cloud, and 80% of companies have experienced an increase in the frequency of cloud attacks. To combat these attacks, encryption is used so that only authorized parties can read the encoding information. Now, encryption has two types,…
What is Public Key Infrastructure (PKI)? Public Key Infrastructure (PKI) is a complex set of hardware, software, policies, and procedures that are used to create, manage, and store digital certificates and keys in a secure way. It serves as the basis of secure communication and authentication methods in digital spaces…
