KEM/DEM: Necessary and Sufficient Conditions for Secure Hybrid Encryption
KEM DEM Secure Hybrid Encryption
2008/12/10
The KEM/DEM hybrid encryption paradigm combines the efficiency and large message
space of secret key encryption with the advantages of public key cryptography. Due to
its simplicity and °exibility, ...
Secure Hybrid Encryption from Weakened Key Encapsulation
Chosen-ciphertext security weak security assumptions hybrid encryption
2008/8/14
We put forward a new paradigm for building hybrid encryption schemes from constrained
chosen-ciphertext secure (CCCA) key-encapsulation mechanisms (KEMs) plus authenticated
symmetric encryption. Con...
Weak adaptive chosen ciphertext secure hybrid encryption scheme
hybrid encryption KEM DEM IND-WCCA
2008/5/21
We propose a security notion named as weak adaptive chosen ciphertext security(INDWCCA)
for hybrid encryption schemes. Although it is weaker than adaptive chosen ciphertext security(INDCCA),
a IND-W...
