Decay

Disintegration of atomic nuclei resulting in the emission of alpha or beta particles (usually with gamma radiation). Also the exponential decrease in radioactivity of a material as nuclear disintegrations take place and more stable nuclei are formed.

Deck

Within aviation, a deck typically refers to the floor area of an aircraft where passengers are seated or cargo is stored, playing a pivotal role in the aircraft's layout and functionality. The design and organization of the deck are crucial for maximizing space efficiency, ensuring passenger comfort, and adhering to safety regulations.

Additionally, the term can also denote the flight deck, the area from which the aircraft is controlled by the flight crew, housing the cockpit and necessary navigation and communication equipment. The flight deck's ergonomic design and technological sophistication are vital for the safe and efficient operation of the aircraft during all phases of flight.

Decryption Key

In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it Encryption doesn't prevent hacking but it reduces the likelihood that the hacker will be able to read the data that is encrypted. In an encryption scheme, the message or information, referred to as plaintext, is encrypted using an encryption algorithm, turning it into an unreadable ciphertext. This is usually done with the use of an encryption key, which specifies how the message is to be encoded. Any adversary that can see the ciphertext should not be able to determine anything about the original message. An authorized party, however, is able to decode the ciphertext using a decryption algorithm, that usually requires a secret decryption key, that adversaries do not have access to. For technical reasons, an encryption scheme usually needs a key-generation algorithm to randomly produce keys.
