As part of daily operations, small businesses may need to collect or exchange sensitive data that should be protected. It could be a financial transaction, a mailing address or some other personally ...

The growth of the Internet of Things and embedded devices requires increasing the secure and energy-efficient communication protocols, whereas conventional cryptographic algorithms usually tend to be ...

In cryptography, a Caesar Cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter ...

Abstract: Protection of data from cyber attacks and illegal access involves the application of cryptographic methods. Using images to encrypt and hide information, visual cryptography presents a new ...

Cloud storage security has become essential as more sensitive personal and business data moves online. While most providers encrypt data at rest and in transit using AES-256 and TLS 1.3, server-side ...

The private communication of individuals and organizations is protected online by cryptography. Cryptography protects our information as it travels over and is stored on the internet—whether making a ...

In the era of pervasive multimedia communication, image data has become a dominant form of information exchange across embedded, mobile, and IoT platforms. This surge in visual data transmission ...

Mobile devices sometimes get lost. A laptop bag gets left on the bus or train, a smartphone slips out of your pocket, or a USB flash drive falls to the ground unnoticed. Losing a notebook or phone ...

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, ...

Encryption can sound like a complex, mysterious topic reserved for security experts. But what if I told you that you can implement strong encryption and decryption with just a few lines of Python? Let ...

The need for secure encryption in IoT and IIoT devices is obvious, and potentially critical for OT and, by extension, much of the critical infrastructure. Chaos is unpredictable – but research ...
