'''Multiple encryption''' is the process of [[encryption|encrypting]] an already encrypted message one or more times, either using the same or a different algorithm. It is also known as '''cascade encryption''', '''cascade ciphering''', '''multiple encryption''', and '''superencipherment'''. '''Superencryption''' refers to the outer-level encryption of a multiple encryption.

Some cryptographers, like Matthew Green of Johns Hopkins University, sayssay multiple encryption addresses a problem that mostly doesn’t exist: ''Modern ciphers rarely get broken... You’re far more likely to get hit by malware or an implementation bug than you are to suffer a catastrophic attack on AES''.<ref>{{cite web |last=Green |first=Matthew |title=Multiple Encryption |url=https://blog.cryptographyengineering.com/2012/02/02/multiple-encryption/ |date=February 2, 2012}}</ref>
