The new signature scheme may be of independent interest. We show that the new scheme is secure in the generic group model. Linear Feedback Shift Registers This article is about Linear Feedback Shift Registers, commonly referred to as LFSRs. The new signature scheme has an interesting property that is has the message space of a cyclic group \(\mathbb_1\) equipped with a bilinear pairing, with efficient protocol to show possession of a signature without revealing the signature nor the message. Our scheme revokes the secret key of the double-spender directly and thus supports more efficient coin tracing. We show a generic construction of compact e-cash schemes from bounded accumulators and signature schemes with certain properties and instantiate it using an existing pairing-based accumulator and a new signature scheme. A bounded accumulator is an accumulator with a limit on the number of accumulated values. linear feedback shift registers (LFSRs) to reduce the hardware cost, unified. Such sequences can easily be generated by linear feedback shift registers (LFSRs). We construct compact e-cash schemes from bounded accumulators. The current GNSS consists of GPS, Global Orbiting Navigation Satellite. Pseudo random sequences play a significant role in several technical areas, such as navigation systems or cryptography. In this paper, we introduce a different approach. Known compact e-cash schemes are constructed from signature schemes with efficient protocols and verifiable random functions.
