Cloud Encryption simply refers to the process whereby your data is encrypted into a secure format to prevent unauthorized access. Here's a simplified structured explanation:
Step 1: Data Encryption Algorithm
The encryption algorithm used by cloud systems includes:
Encryption (One key is symmetric, AES, and two keys are asymmetric encryption: public for encryption and private for decryption).
Step 2: In transit data encryption
The data is encrypted with methods like AES (Advanced Encryption Standard) to prevent unauthorized access when it is stored.
Step 3: Data in motion encryption
In computing, when data is transferred between systems or users, protocols such as TLS (Transport Layer Security) guarantee the key encryption of data while transferring the data.
Step 4: Encryption Key Generation
Unique keys are generated to encode the data. The keys are essential for decrypting the information later on.
Step 5: Decryption Operation
Authorized users or systems employ the correct key to recover the encrypted data back into its original format.
Step 6: Secure Key Management
Keys are stored securely either by the cloud provider or the user. Proper key management prevents unauthorized access and ensures the availability of data.
Step 7: User or System Access
Data can be encrypted only by authorized entities through proper authentication, and key usage can be accessed.
Encryption in the cloud keeps your data private; that is, confidentiality and security are both important for information that is stored and transmitted.
