Encryption-Scheme Security in the Presence of Key-Dependent Messages
ACM Symposium on Applied Computing, pp. 62-75, 2003.
Encryption that is only semantically secure should not be used on messages that depend on the underlying secret key; all bets are off when, for example, one encrypts using a shared key K the value K. Here we introduce a new notion of security, KDM security, appropriate for key-dependent messages. The notion makes sense in both the public-...More
