This presentation discusses various aspects of data encryption. It defines data encryption as mathematical calculations and algorithms that transform plain text into ciphertext. It then covers the main types of encryption, distinguishing between symmetric encryption which uses the same key for encryption and decryption, and asymmetric encryption which uses different public and private keys. The presentation also explains some common encryption methods like the Data Encryption Standard and public key cryptosystems.

- 1. A PRESENTATION ON “DATA ENCRYPTION” Presented by: Anu bala Roll no 3373
- 2. Data encryption definition. Types of data encryption. Difference between symmetric and asymmetric. Encryption Methods. Data Encryption Standard (DES). Public Key Cryptosystem CONTENT
- 3. Data encryption refers to mathematical calculations and algorithmic schemes that transform plaintext into cyphertext, a form that is non-readable to unauthorized parties. The recipient of an encrypted message uses a key which triggers the algorithm mechanism to decrypt the data, transforming it to the original plaintext version Data encryption definition
- 5. *plaintext *encryption algorithm *public and private key *cipher text * decryption algorithm A public key encryption scheme has six ingredients
- 6. In symmetric (Single key): The encryption and decryption keys are the same. Types of data encryption
- 7. . Symmetric key encryption is also known as private encryption, because it uses the same key and same cryptographic algorithm to encrypt and decrypt data.
- 8. A symmetric encryption scheme has five ingredients * Plaintext * Encryption Algorithm * Secret key * Cipher Text * Decription
- 9. In asymmetric (two keys): The encryption and decryption keys are different. .

- 11. The symmetric one key is used for symmetric and a symmetric but in asymmetric different keys are use for encryption and description. In symmetric, sender and receiver must share the algorithm and key but in a symmetric sender and receiver must have one matched pair of keys. In symmetric key must be kept secret but in asymmetric two keys must of kept secret. Difference b/w Asymmetric & Symmetric Encryption
