A Digital Signature Scheme with Information Recovery Function Based on the Elliptic Curve Belt
GU Da-gang · Journal of Guiyang University · 2008
Digital signature technology can not only provide encrypt and decrypt but determine the identity of participants,prevent malicious forgery and distortion and play am important role in the safety of network service.Compared with other public-key cryptosystem,the elliptic curve cryptosystem has the advantages of higher safety,less computing load,shorter encryption key and occupying less bandwidth.The new signature scheme with message recovery based on the elliptic curve gives the way to test and defy agreements,discusses the safety of the scheme and solves the problem of the message recovery which can not be realized by the general ECC signature scheme.
