Endtoendsalausmenetelmä

Endtoendsalausmenetelmä, often referred to as end-to-end encryption (E2EE), is a communication method that ensures only the sender and the intended recipient can read the messages. This means that any intermediate parties, including the service provider hosting the communication platform, cannot decipher the content. The process typically involves encrypting data on the sender's device and decrypting it on the recipient's device. Keys required for encryption and decryption are generated and managed exclusively on the end-user devices, preventing any third party from accessing them.

The core principle of E2EE relies on cryptography. When a message is sent, it is encrypted using a unique key that only the recipient possesses. This encrypted message travels through the network, and when it reaches the recipient's device, it is decrypted using their corresponding key. This robust security feature is widely adopted in messaging applications, secure email services, and other communication platforms to protect user privacy and sensitive information from unauthorized access, surveillance, or data breaches. The implementation of E2EE varies across different platforms, but the fundamental goal remains the same: to secure communication at its endpoints.
