Encryption for strong security
Network use various encryption systems that help my private from others. So we must encrypt information when we use
Internet.
Data Encryption
● The real data is buried in the pseudorandom “noise.”This is called data encryption.
File Encryption
● Local file encryption protects data from physical intrusion
Link Encryption
● This is an approach to communications security that encrypts and decypts all traffic at each end of communications line.
Key
In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a
key, the algorithm would have no result. In encryption, a key specifies the particular
transformation of plaintext into ciphertext, or vice versa during decryption. Keys are also used in other cryptographic algorithms, such as digital signature schemes and message authentication
codes.
