A Method for Fast Revocation of Public Key Certificates and Security Capabilities
Public Key Certificate Security Capabilities
2015/8/5
We present a new approach to fast certificate revocation centered around the concept of an on-line semi-trusted mediator (SEM). The use of a SEM in conjunction with a simple threshold variant of the R...
Chosen-Ciphertext Security from Identity-Based Encryption
Identity-Based Encryption Chosen-Ciphertext Security
2015/8/5
We propose simple and efficient "CCA-secure" public-key encryption schemes (i.e., schemes secure against adaptive chosen-ciphertext attacks) based on any identity-based encryption (IBE) scheme. When i...
