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.
Context ∞ End-to-end encryption is a critical subject in crypto news, particularly concerning privacy-focused digital assets and secure communication within decentralized applications. Discussions often involve debates between privacy advocates and government agencies seeking access to encrypted communications for national security or law enforcement purposes. Reports may highlight how various blockchain projects leverage E2EE for secure messaging or confidential transaction metadata. The ongoing tension between user privacy and regulatory demands continues to shape the implementation and legal standing of this technology.
