Encryption

The coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.

encryption

The manipulation of data to prevent accurate interpretation by all but those for whom the data is intended. Financial institutions use encryption to increase the security of data transmitted via the Internet.

Any minor change in a plain-image should lead to a significant difference in the cipher-image to satisfy an ideal encryption algorithm. For the plain-image Lena, Figure 5(a) shows the cipher-image when there is a one-bit change in the plain-image, whereas Figure 5(b) depicts the difference before and after the one-bit change.

Just like Windows-based ransomware, it encrypts the contents of these files using AES (a symmetric key encryption algorithm), which provides enough strength and speed while keeping system resources usage to a minimum.
