ECC-Based Multi-Document Fail-Stop Signature Encryption Scheme
摘要
Although digital information development brings greater convenience to people’s everyday lives via information technology in recent advancements, digital information content is incredibly easy to be eavesdropped, counterfeited, and distorted to alter genuine knowledge after it is digitized to produce fake ones. How to ensure that the information cannot be subjected to be intercepted, comprised or tampered with is a major concern of information security. In other words, the authenticity, integrity, non-repudiation and confidentiality of the electronically transmitted data must be maintained from sender to receiver. Like other security practices, a ＂digital signature＂ has been extensively used in many secure protocols and can fulfill the aforementioned requirements. This paper presents an improved ＂failstop signature＂ (FSS) approach which uses ＂elliptic curve cryptography＂ (ECC) to provide higher security and better performance for ＂multi-document＂ authentication. With the signature design of encryption function, users not only can employ the avalanche effect of unsystematic properties to chaotically generate mutual secure cipher keys against the counterfeiting problems, but also apply advantage of the size of the key required for encryption and ＂digital signatures＂ to rapidly perform digital transmission of the document-ciphertext message in diverse network environments.
