An Improved Scheme of the Gennaro-Krawczyk-Rabin Undeniable Signature System Based on RSA,ify the signature even if a signer wants to restrict the verifiers to confirm his signatures. D. Chaum et al.[.] proposed undeniable signatures to solve this problem. These signatures are based on the discrete logarithm problem and are extended to those with different properties [.]-[.]. After that,

Efficient and Secure Member Deletion in Group Signature Schemes,can reveal the identity of the member. During last decade, group signature schemes have been intensively investigated in the literature and applied to various applications. However, there has been no scheme properly handling the situation that a group member wants to leave a group or is excluded by

An Efficient and Practical Scheme for Privacy Protection in the E-Commerce of Digital Goods,ducation and legislation, but also from cryptographic technologies. In this paper we propose and analyze a privacy protection scheme for e-commerce of digital goods. The scheme takes cryptography as its technical means to realize privacy protection for online customers. It is efficient in both compu

Efficient Sealed-bid Auction using Hash Chain,h chain, we can drastically reduce the time needed for bidding and opening bids. If we use a practical hash function e.g. SHA-1, our method is 200,000 times faster than former methods that use public key cryptosystems. Accordingly, our method is capable of wide application in terms of the number of

Micropayments for Wireless Communications,schemes seem well suited to this scenario since they are specifically designed for efficient operation. Most micropayment schemes require a digital signature and therefore users must support public key operations and, furthermore, a public key infrastructure must be available. Such schemes are not s

Ju-Sung Kang,Seongtaek Chee,Choonsik Parkg, and Math all depend on Technology to visualize and solve problems. Technology assists the other STEM fields to be creative but also carries with it its own social and cultural implications. To discuss the nature of technology we must first come to a shared definition of technology. This task can

Hidema Tanaka,Chikashi Ishii,Toshinobu KanekoEM still remains ambiguous and needs to be explicitly defined and agreed upon. Is STEM simply each associated field or it is a more complex entity that integrates the field disciplines? The state of Indiana has responded to this national call for increased STEM by integrating it increasingly within
