WebSince the 1970s, other tasks (e.g., signature schemes) have been recognized as falling within the domain of Cryptography (and even being at least as central to Cryptography). Yet the construction of encryption schemes remains, and is likely to remain, a central enterprise of Cryptography. WebCommitment schemes have important applications in a number of cryptographic protocols including secure coin flipping, zero-knowledge proofs, and secure computation . A way to visualize a commitment scheme is to think of a sender as putting a message in a locked box, and giving the box to a receiver.

As with all security-related systems, it is important to identify potential weaknesses. Aside from poor choice of an asymmetric key algorithm (there are few which are widely regarded as satisfactory) or too short a key length, the chief security risk is that the private key of a pair becomes known. All security of messages, authentication, etc., will then be lost. All public key schemes are in theory susceptible to a "brute-force key search attack". However, s…
