Solution to the encryption in the cybersecurity strategy
The print version of Sweden’s national cybersecurity strategy 2025–2029 – a new era of cybersecurity contains an encryption to solve. The solution to the encryption is shown below.
The encrypted text on page 40 of the Cybersecurity Strategy reads: ELNWE IAGEL CEERY RIESD WHILE FBSUT ASITE NTHHV OYRCI
The solution can be found using the transposition method. Transposition ciphers (also known as permutation ciphers) are a method of encryption that reorders letters (transposition) without changing the letters themselves.
By writing cipher in columns and then reordering the columns, the text can be read in rows.
