Generic Construction of Certificate-Based Encryption from Certificateless Encryption Revisited
Certificateless public key encryption (CLE) and certificate based encryption (CBE) are two novel public key cryptographic primitives requiring no authenticity verification of the recipient’s public key. Both of them are motivated to simultaneously solve the heavy certificate management problem inherent in the traditional public key encryption (PKE) and the key escrow problem inherent in the ide...
متن کاملFurther Observations on Certificate-Base Encryption and its Generic Construction from Certificateless Public Key Encryption
Certificate-based encryption (CBE) is a new asymmetric encryption paradigm which was introduced to solve the certificate management problem in traditional public key encryption (PKE). It combines PKE and identity-based encryption (IBE) while preserving some of their most attractive features. CBE provides an efficient implicit certificate mechanism which eliminates the third-party queries and si...
متن کاملForward-Secure Certificate-Based Encryption and its Generic Construction
In this paper, we introduce a new asymmetric encryption paradigm called Forward-Secure CertificateBased Encryption. It preserves the advantages of certificatebased encryption (CBE) such as implicit certificate and no private key escrow. At the same time it also inherits the properties of the forward-secure public key encryption. In a forward-secure CBE scheme, all users’ private keys are update...
متن کاملGeneric Certificateless Encryption in the Standard Model
Despite the large number of certificateless encryption schemes recently proposed, many of them have been found to be insecure under a practical attack called malicious-but-passive KGC attack, since they all follow the same key generation procedure as that of the one proposed by Al-Riyami and Paterson in ASIACRYPT 2003. The only scheme that remains secure against this attack is due to Libert and...
متن کاملThreshold Certificate-based Encryption
Certificate-based encryption (CBE) is a new asymmetric encryption paradigm which combines traditional public-key encryption (PKE) and identity based encryption (IBE) while preserving some of their most attractive features. CBE provides an efficient implicit certificate mechanism to eliminate third-party queries for the certificate status and to simply the certificate revocation problem. Therefo...
