End-to-End Encryption

Definition

End-to-end encryption is a secure communication method where only the communicating users can read the messages. This cryptographic system ensures that data is encrypted at the sender’s device and remains encrypted until it reaches the recipient’s device. Intermediaries, including service providers, cannot access the unencrypted content, guaranteeing privacy and data integrity. Each message is secured with unique keys, preventing eavesdropping and tampering during transmission.
