A process that transforms readable data into a coded format to prevent unauthorized access.
Description
Encryption is a fundamental aspect of cybersecurity that secures sensitive information by converting it into a format that cannot be easily understood by unauthorized users. This process uses algorithms and keys to change data into ciphertext, which can only be decrypted back to its original form by someone who possesses the correct decryption key. In today's digital age, where cyber threats are prevalent, encryption plays a crucial role in protecting personal data, financial information, and business communications. For instance, when you make an online purchase, your payment information is encrypted to protect it from hackers. Similarly, messaging apps like WhatsApp use end-to-end encryption to ensure that only the sender and recipient can read the messages. As cyber threats evolve, encryption technologies continue to advance, making it a vital tool for safeguarding data integrity and confidentiality across various industries.
Examples
- Online banking transactions use encryption to secure personal and financial information.
- Messaging applications like Signal employ end-to-end encryption to protect user conversations from prying eyes.
Additional Information
- Encryption is essential for compliance with regulations such as GDPR and HIPAA.
- Common encryption standards include AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman).
