In the past decades related-key attacks have been studied in theory and practice and invulnerability against related-key attacks as one of the security goals has been considered in the design of block ciphers. Cipher assessment against all kinds of attacks leads to identify their vulnerabilities and improving the cryptographic schemes. Related-key impossible boomerang attack is made of the combination of boomrang attack and related-key impossible differential attacks. The flexibility to choose key differences provides the possibility of attack on more rounds of block ciphers using this attack. Recently, SIMON family of Lightweight cipher has been designed securely and flexibly by NSA in ten versions for the proper functioning in limited hardware environments. SIMON key scheduler is proposed invulnerable to related-key attacks.In this paper related-key impossible boomerang attack on 20 rounds Simon32/64 lightweight cipher is presented.
