Off-Line Electronic Cash Based on Secret-Key Certificates
An oo-line electronic coin system is presented that ooers multi-party security and unconditional privacy of payments. The system improves signiicantly on the eeciency of the previously most eecient such system known in the literature, due to application of a recently proposed technique called secret-key certiicates. By deenition of secret-key certiicates, pairs consisting of a public key and a ...
متن کاملAn Efficient Off-line Electronic Cash System with Revocable Anonymity
Numerous anonymity revocation mechanisms have been proposed for off-line e-cash system in the last decade. Within this category of payment systems, two primary considerations are double-spending detection and tracing capability. However, most designs and existing solutions for these two basic requirements are inefficient or impractical. In this paper, an efficient e-cash with anonymity revocati...
متن کاملSecure untraceable off-line electronic cash system
Electronic cash; Payment systems; Untraceable; Date attachable. Abstract Eslami and Talebi (2011) [25] proposed an untraceable electronic cash scheme and claimed that their scheme protects the anonymity of customers, detects the identity of double spenders and provides the date attachability of coins to manage the bank database. In this paper, illustrating Eslami and Talebi’s scheme, as one of ...
متن کاملCryptanalysis on "Secure untraceable off-line electronic cash system"
Recently, Baseri et al. proposed a secure untraceable off-line electronic cash system. They claimed that their scheme could achieve security requirements of an e-cash system such as, untraceability, anonymity, unlinkability, double spending checking, un-forgeability, date-attachability, and prevent forging coins. They further prove the un-forgeability security feature by using the hardness of d...
متن کاملSecurity Analysis on Secure Untraceable Off-line Electronic Cash System
In 2013, Baseri et al. proposed an untraceable off-line electronic cash scheme from the RSA cryptosystem. They used a method that injects the expiration date and the spenders identity onto the coin to prevent double spending. The authors claimed that the scheme provides the properties of anonymity, unforgeability, double spending detection, and date attachability. Unfortunately, we find that th...
