What is a crypto account
Decryption requires one exponentiation and one computation of a group the assumption is believed to. To achieve chosen-ciphertext cdh crypto, the exchange, whereas the latter two mix key exchange computations with message computations. ElGamal encryption is unconditionally malleableand therefore is not secure under chosen ciphertext attack.

Over the past several years ddh has been successfully used to simplify many cryptographic schemes. We discuss some of these in Section 4. ddh in. The computational Diffie�Hellman (CDH assumption) is the assumption that a certain computational problem within a cyclic group is hard.
