This asymmetry creates an imbalance of power in transactions, which can sometimes cause the transactions to go awry, a kind of market failure in the worst case. Symmetric encryption algorithms are either block ciphers or stream ciphers, and include algorithms like DES, TDEA/3DES, AES, etc. Some asymmetric information models can also be used in situations where at least one party can enforce, or effectively retaliate for breaches of, certain parts of an agreement, whereas the other(s) cannot.
