Word scramble
Unscramble the letters and write each key term on the line.
1
TTOBIIUSNUST IPHCRE
A cipher that swaps each letter for a different letter or symbol using a key table, like a scrambled alphabet. It is not a simple shift, and the table is used in reverse to decrypt.
2
ONIRSANTPSTOI IEHPCR
A cipher that keeps the same letters but rearranges their order by a rule, like writing them in a zigzag on two rails and reading off the rows.
3
PEEK ETH YEK EERSTC
Encryption is only as strong as its key. Never send the key with the message, share it in person or by another channel, and change it if it may have leaked.
4
EWKA IREPHC
A cipher with few keys and letter patterns that show through, so a computer can break it fast. Modern encryption uses huge keys and complex steps. A Caesar cipher has only 25 keys.
5
RYEDELA TCIEYSRU
Using several protections together, such as a strong passphrase, MFA, updates and encryption, so if one fails the others still keep your account and data safe.
6
LPAPY OTPRECNTSOI
Read a scenario, name the threat, explain how it works, then suggest measures like MFA or encryption and say why they reduce the harm.
7
NRAEWSASE SSGEEMA
A poster, infographic or short video that tells an audience how to spot one cyber threat and what to do about it. It uses one clear message and is fact-checked before it is shared.
8
ADTLIGI NRTEPIATUO
The impression other people form of you from the data in your digital footprint, such as posts, photos and comments that show up when someone searches your name.
9
VSERER OGL
A record a web server makes for every visit, such as the IP address, device type, time and pages viewed, even when the visitor types nothing in.

1TTOBIIUSNUST IPHCRE → substitution cipher — A cipher that swaps each letter for a different letter or symbol using a key table, like a scrambled alphabet. It is not a simple shift, and the table is used in reverse to decrypt.
2ONIRSANTPSTOI IEHPCR → transposition cipher — A cipher that keeps the same letters but rearranges their order by a rule, like writing them in a zigzag on two rails and reading off the rows.
3PEEK ETH YEK EERSTC → keep the key secret — Encryption is only as strong as its key. Never send the key with the message, share it in person or by another channel, and change it if it may have leaked.
4EWKA IREPHC → weak cipher — A cipher with few keys and letter patterns that show through, so a computer can break it fast. Modern encryption uses huge keys and complex steps. A Caesar cipher has only 25 keys.
5RYEDELA TCIEYSRU → layered security — Using several protections together, such as a strong passphrase, MFA, updates and encryption, so if one fails the others still keep your account and data safe.
6LPAPY OTPRECNTSOI → apply protections — Read a scenario, name the threat, explain how it works, then suggest measures like MFA or encryption and say why they reduce the harm.
7NRAEWSASE SSGEEMA → awareness message — A poster, infographic or short video that tells an audience how to spot one cyber threat and what to do about it. It uses one clear message and is fact-checked before it is shared.
8ADTLIGI NRTEPIATUO → digital reputation — The impression other people form of you from the data in your digital footprint, such as posts, photos and comments that show up when someone searches your name.
