Encryption does not itself prevent interference, but denies the intelligible content to a would-be interceptor. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, considerable computational resources and skills are required. Communicating parties must have the same key in order to achieve secure communication. However, only the receiving party has access to the decryption key that enables messages to be read. 2010 and is regularly updated.

Encryption has long been used by militaries and governments to facilitate secret communication. It is now commonly used in protecting information within many kinds of civilian systems. In response to encryption of data at rest, cyber-adversaries have developed new types of attacks. There have been numerous reports of data in transit being intercepted in recent years.

A single error in system design or execution can allow successful attacks. Sometimes an adversary can obtain unencrypted information without directly undoing the encryption. Encrypting at the time of creation is only secure if the encryption device itself has not been tampered with. Cryptography offers a way of making the erasure almost instantaneous. Because the key is stored on the same device, this setup on its own does not offer full confidentiality protection in case an unauthorised person gains physical access to the device.
