This allows the third party to provide search and other features, or to scan for illegal and unacceptable content, but also means they can be read and misused by anyone who has access to the stored messages on the third-party system, whether this is by design or via a backdoor.

It does not prevent the company itself from viewing the information, as they have the key and can simply decrypt this data. Server-side disk encryption simply prevents unauthorized users from viewing this information. Even if the messages are encrypted, they are only encrypted 'in transit', and are thus accessible by the service provider, regardless of whether server-side disk encryption is used. In many messaging systems, including email and many chat networks, messages pass through intermediaries and are stored by a third party, from which they are retrieved by the recipient. In 2022, the UK's Information Commissioner's Office, the government body responsible for enforcing online data standards, stated that opposition to E2EE was misinformed and the debate too unbalanced, with too little focus on benefits, since E2EE 'helped keep children safe online' and law enforcement access to stored data on servers was 'not the only way' to find abusers.

The recipients retrieve the encrypted data and decrypt it themselves.īecause no third parties can decipher the data being communicated or stored, for example, companies that provide end-to-end encryption are unable to hand over texts of their customers' messages to the authorities. The messages are encrypted by the sender but the third party does not have a means to decrypt them, and stores them encrypted. Įnd-to-end encryption is intended to prevent data being read or secretly modified, other than by the true sender and recipient(s). As such, no one, including the communication system provider, telecom providers, Internet providers or malicious actors, can access the cryptographic keys needed to converse.
