Levels of Double Strength Encryptionĭouble strength encryption includes various levels of encryption that are explained here under − First layer of encryption The other names for double strength encryption include cascade encryption or cascade ciphering. It requires parties interested in secure communication channel to achieve privacy.ĭouble strength encryption, also called as multiple encryption, is the process of encrypting an already encrypted text one or more times, either with the same or different algorithm/pattern. It uses mathematical algorithms for securing the information. The basic characteristics of modern cryptography are as follows − The diagram given below shows an illustration of the complete process of cryptography − Characteristics of Modern Cryptography The process of converting cipher text to plain text is called decryption. The process of converting plain text to cipher text is called encryption. Cipher TextĬipher text is the message obtained after applying cryptography on plain text. The plain text is the message which undergoes cryptography. The plain text message is the text which is readable and can be understood by all users.

The frequently used terms in cryptography are explained here − Plain Text The science of cryptography emerged with the basic motive of providing security to the confidential messages transferred from one party to another.Ĭryptography is defined as the art and science of concealing the message to introduce privacy and secrecy as recognized in information security. Decryption of Simple Substitution CipherĬryptography is the art of communication between two users via coded messages.
