Security researchers discovered multiple vulnerabilities earlier this year that affect practically every PC, laptop, and smartphone on the market. The flaws, known as Spectre and Meltdown, are found in the design of modern CPUs and allow personal data (passwords, e-mail, and surfing history) to be accessed from memory by exploiting Speculative Execution and Branch Prediction capabilities. The features are performance-enhancing technologies that enable processors to pre-execute instructions and forecast future execution routes.The Meltdown vulnerability is thought to be very simple to cure. Still, due to the nature of Speculative Execution, we will most likely have to settle with mitigation in ... Read More

AES encryption defines the phase of hiding electronic information using an approved 128-bit, 192-bit, or 256-bit symmetric encryption algorithm from the Advanced Encryption Standard (AES), also called a FIPS 197.In the 1990s, the US Government required to standardize a cryptographic algorithm which was to be used globally by them. It is known as the Advance Encryption Standard (AES).Several proposols were submitted and after multiple debate, an algorithm known as Rijndael was accepted. Rijandael was invented by Joan Daemen and Vincent Rijmen. The need for appearing up with a new algorithm was actually because of recognized weakness in DES.The 56-bit keys ... Read More

EncryptionData encryption is a method of translating information from plaintext (unencrypted) to ciphertext (encrypted). Users can access encrypted information with an encryption key and decrypted information with a decryption key.There are large amounts of sensitive information handled and stored online in the cloud or on combined servers. Encryption needs cybersecurity to protect against brute-force and cyber-attacks, such as malware and ransomware.Data encryption operates by protecting transmitted digital information on the cloud and computer systems. There are two types of digital information, transmitted information or in-flight information and stored digital information or data at rest.The main objective of data encryption is ... Read More
