The Collision Security of Tandem-DM in the Ideal Cipher Model
Collision Security Tandem-DM Cipher Model
2012/12/3
We prove that Tandem-DM, which is one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resistance in the ide...
On the Security of Tandem-DM
Cryptographic hash function blockcipher based proof of security
2009/6/11
We provide the first proof of security for Tandem-DM, one of the oldest and most well-
known constructions for turning a blockcipher with n-bit blocklength and 2n-bit keylength into a
2n-bit cryptog...
