Bit commitment
Bit commitment is a protocol between two mistrusting parties, Alice and ... to reveal the value X to Bob. The functionality of a bit commitment protocol can be compared with that of a safe as follows: To ... key to Bob who opens the safe and reads the value of X. Bit commitment is an important cryptographic primitive as it can be used as a ...

Coin tossing
... A generic example of a coin tossing protocol is based on bit commitment . Alice first chooses a random bit r 1 and then uses the bit commitment scheme to commit to this bit. Bob then chooses another random ...
