Forward-Secure Blind Signature Scheme Based on the Strong RSA Assumption
Key exposure problem turns out to be very serious in security services. For example, in electronic cash, the problem is very severe since money is directly involved. In other applications of cryptography, it is also a devastating attack. Forward security is the first security notion addressing the this issue. Roughly speaking, forward secrecy is aimed to protect validity of the all usage before...
متن کاملAn Efficient Direct Anonymous Attestation Scheme with Forward Security
Direct Anonymous Attestation (DAA) is a cryptographic mechanism adopted by the Trusted Computing Group in its specifications for trusted computing platforms (TCP). In this paper, we propose a new DAA scheme and prove it is secure under the strong RSA assumption and the decisional Diffie-Hellman assumption. While satisfying all the security properties proposed in previous DAA schemes, our scheme...
متن کاملA Forward Secure Direct Anonymous Attestation Scheme
Direct Anonymous Attestation (DAA) is a cryptographic mechanism that enables remote authentication of a Trusted Platform Module (TPM) while preserving its privacy. In this paper, we propose a new DAA scheme based on the strong RSA assumption and the decisional Diffie-Hellman assumption. While satisfying all the security properties proposed in previous DAA schemes, our scheme provides a new desi...
متن کاملStrong Forward Security in Identity-Based Signcryption
Due to the possibility of key exposure, forward security in encryption and signing has been well studied, especially in the identitybased setting where an entity’s public key is that entity’s name. From an efficiency point of view, one would like to use the signcryption primitive and have the best of both worlds. However, strong forward security, where the adversary cannot signcrypt in sender’s...
متن کاملOne-round Strongly Secure Key Exchange with Perfect Forward Secrecy and Deniability
Traditionally, secure one-round key exchange protocols in the PKI setting have either achieved perfect forward secrecy, or forms of deniability, but not both. On the one hand, achieving perfect forward secrecy against active attackers seems to require some form of authentication of the messages, as in signed Diffie-Hellman style protocols, that subsequently sacrifice deniability. On the other h...

Key exposures bring out very serious problems in security services. Especially, it is more severe in the applications such as electronic cash or electronic payment where money is directly involved. Forward secrecy is one of the security notions addressing the key exposure issues. Roughly speaking, forward secrecy is aimed to protect the validity of all actions using the secret key before the ke...
