Secure Hash Algorithm (Secure Hash Algorithm) get the attention of the security business as the excellent signature Al-gorithm at its birth, SHA-1 which is because of its safety and efficiency have been widely used in various fields around the world. But faced with the vast information to be signed, it will no longer competent for the traditional algorithm. This paper focus on SHA-1 algorithm based on big data research, through transforming the hash computation steps, put forward a distributed cloud model, finally reduce the space complexity of the algorithm to improve calculation efficiency ultimately.
