Data Encryption
ConceptAbout
Data encryption is a crucial security method that transforms readable data, known as plaintext, into an unreadable format called ciphertext. This process ensures that only authorized individuals with the decryption key can access the encrypted data. Encryption protects data from unauthorized access, theft, or alteration, both when it is stored (at rest) and when it is being transmitted (in transit). It is widely used in various sectors, including finance, healthcare, and government, to safeguard sensitive information. Encryption methods include symmetric and asymmetric encryption. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption employs a public key for encryption and a private key for decryption. Key management is critical in maintaining the security of encrypted data. Encryption algorithms, such as the Advanced Encryption Standard (AES), are commonly used to ensure data confidentiality and integrity. By employing encryption, organizations can comply with data protection regulations and ensure the privacy of sensitive information.
