Encryption
• Encryption is the most effective way to achieve data security
• Encryption is the process of converting data to an unrecognizable or "encrypted" form.
• Encryption is also used to secure data sent over wireless networks and the Internet
why is it important?
• Encryption is important because it allows you to securely protect data that you don't want anyone else to have access to.
Why use encryption?• Authentication
• Protects personal data such as passwords.
Privacy• Provides for confidentiality of private
information.
• Integrity• Ensures that a document or file has not
been altered.
Examples of Encryption• Web browser encryption
• Email encryption
• Hard drive encryption
How it works??
• Start with a message that has to be sent securely. This could be
Text.Numeric Data.Secret Codes
Next we need an encryption key. This could be a phrase like My secret password phrase�
The computer receiving the message knows the digital key and so is able to work out the original message.
Encryption methods
• Hashing EncryptionSince a hash is unique to a specific message, even minor changes to that message result in a dramatically different hash, thereby alerting a user to potential tampering. Some common hashing algorithms are Message Digest 5 (MD5) and Secure Hashing Algorithm (SHA).
• Symmetric Methods– also called private-key cryptography, is one of the
oldest and most secure encryption methods– A sender encodes a message into ciphertext using
a Private key, and the receiver uses the same key to decode it
• Asymmetric Forms Asymmetric, or public key, cryptography is,
potentially, more secure than symmetric methods of encryption.
Uses two keys, a "private" key and a "public key," to perform encryption and decryption
