Certificate-based encryption (CBE) is a new paradigm which overcomes the shortcomings of traditional public-key encryption (PKE) and identity based encryption (IBE). CBE provides an efficient implicit certificate mechanism to eliminate third-party queries for the certificate status and to simplify the certificate revocation problem in traditional PKI. Therefore, CBE can be used to construct an efficient...
Certificate-based encryption (CBE) is a new paradigm which combines traditional public-key encryption (PKE) and identity-based encryption (IBE) while preserving their features. CBE provides an efficient implicit certificate mechanism to eliminate third-party queries for the certificate status and to simplify the certificate revocation problem. Therefore, CBE can be used to construct an efficient PKI...
Certificate-based encryption (CBE) is a new asymmetric encryption paradigm which combines public-key encryption (PKE) and identity based encryption (IBE) while preserving their features. CBE provides an efficient implicit certificate mechanism and allows a periodical update of certificate status while eliminating third-party queries for the certificate status. In addition, it also solves the key escrow...
Certificate-based encryption (CBE) is a new paradigm which overcomes the shortcomings of traditional public-key encryption and identity based encryption. CBE provides an efficient implicit certificate mechanism to eliminate third-party queries for the certificate status and to simplify the certificate revocation problem. Therefore, CBE can be used to construct an efficient PKI requiring fewer infrastructures...
In Eurocrypt 2003, Gentry introduced a new public key encryption paradigm called certificate-based encryption (CBE) to overcome the drawbacks of the conventional PKI and the identity based encryption (IBE). CBE provides an efficient implicit certification mechanism and allows a periodical update of certificate status while eliminating third-party queries for the certificate status. In addition, it...
The Fujisaki-Okamoto (FO) conversion is a generic conversion to enhance a public key encryption scheme with security of one-way against chosen plaintext attacks (OW-CPA) to security of indistinguishable against adaptive chosen ciphertext attacks (IND-CCA) in the random oracle model. Existing works have shown that the FO conversion also can generically upgrade the security of the identity-based encryption...
