Davies attack

Davies’ attack refers to a cryptographic attack on certain types of public-key cryptosystems, particularly those based on the RSA algorithm. It is named after the cryptographer Donald Davies, who is known for his work in cryptography and secure communications. In a more specific context, Davies’ attack exploits certain properties of RSA when an attacker has access to multiple ciphertexts that have been encrypted with the same key but potentially different plaintexts.
