How does encryption contribute to securing data in the cloud, and what types of encryption are most commonly used?
Encryption plays a crucial role in securing data stored in the cloud by transforming information into a coded form that only authorized parties can decode. This ensures that even if unauthorized individuals access the data, they cannot read or use it without decryption keys.
Some commonly used encryption types in cloud security include:
1. AES (Advanced Encryption Standard): Widely used symmetric encryption algorithm considered highly secure and efficient.
2. RSA (Rivest-Shamir-Adleman): Asymmetric encryption algorithm commonly used for key exchange and digital signatures.
3. TLS/SSL (Transport Layer Security/Secure Sockets Layer): Protocols that establish encrypted connections between servers and clients for secure data transmission.
4. SHA (Secure Hash Algorithm): Used to generate hash values from data, ensuring data integrity and authentication.
5. PGP (Pretty Good Privacy): Encryption program commonly used for securing emails and data files.
Encrypting data in the cloud helps protect it from unauthorized access, data breaches, and interception during transmission, thereby enhancing overall security and privacy.
