Word scramble
Unscramble the letters and write each key term on the line.
1
TAFFS URRPDECOE
A documented rule employees must follow, such as reporting incidents or locking devices, to reduce cyber security risk.
2
TCOPNYEINR
Turning a readable message into a scrambled, unreadable message using a key, so it can only be read again with decryption.
3
SAERAC PRCIEH
A cipher that encrypts a message by shifting each letter forward by a fixed number, and decrypts it by shifting each letter back by the same number.
4
ALEBTYOPIPLAHC RICPHE
A cipher that uses a repeating list of shift numbers, so different letters in a message are shifted by different amounts.
5
GEIEERNV HICPER
A cipher that uses a keyword, where each keyword letter sets a different shift for the matching letter of the message.
6
YMEIRSTMC ROCYINPNTE
Using the exact same secret key to both lock and unlock a message.
7
EAS
A widely used method of symmetric encryption that uses one shared key, which can be 128, 192, or 256 bits long, to lock and unlock data.
8
SATEIMMCRY NOTYCREPIN
Encryption that uses a linked pair of keys: a public key to encrypt data and a private key to decrypt it, with no shared secret key needed.
9
SRA
A way of locking and unlocking messages using two matching keys: a public key anyone can have, and a private key kept secret by its owner.

1TAFFS URRPDECOE → Staff procedure — A documented rule employees must follow, such as reporting incidents or locking devices, to reduce cyber security risk.
2TCOPNYEINR → Encryption — Turning a readable message into a scrambled, unreadable message using a key, so it can only be read again with decryption.
3SAERAC PRCIEH → Caesar cipher — A cipher that encrypts a message by shifting each letter forward by a fixed number, and decrypts it by shifting each letter back by the same number.
4ALEBTYOPIPLAHC RICPHE → Polyalphabetic cipher — A cipher that uses a repeating list of shift numbers, so different letters in a message are shifted by different amounts.
5GEIEERNV HICPER → Vigenere cipher — A cipher that uses a keyword, where each keyword letter sets a different shift for the matching letter of the message.
6YMEIRSTMC ROCYINPNTE → Symmetric encryption — Using the exact same secret key to both lock and unlock a message.
7EAS → AES — A widely used method of symmetric encryption that uses one shared key, which can be 128, 192, or 256 bits long, to lock and unlock data.
8SATEIMMCRY NOTYCREPIN → Asymmetric encryption — Encryption that uses a linked pair of keys: a public key to encrypt data and a private key to decrypt it, with no shared secret key needed.
9SRA → RSA — A way of locking and unlocking messages using two matching keys: a public key anyone can have, and a private key kept secret by its owner.
