Description
A fast multi-functional encipherment scheme named ECURVE2 is developed by using one-way functions on elliptic curve. ECURVE2 presents an encipherment scheme to assist one to multi-point cryptographic communication and recipients threshold control. In the scheme, the amount of header, which necessarily occurs accompanying the elliptic curve ciphertext, is reduced. For enciphering data stream, the repetitive hash function - common key cipher scheme is hired instead of conventional hash function - masking scheme. As a result, fast encipherment of data stream in the multi-point cryptographic communication and recipients threshold control is realized in the elliptic curve public key cryptosystem.
