Self-Generated-Certificate Based Cryptographic Protocol with Lite Certificate Management

In spite of the vital role played by Digital Certificates in Public Key Cryptographic systems, the overhead involved in maintaining those made them prohibitory. Certificateless Public Key Cryptography [1] was proposed as an alternative. It was based on based on the concept of implicit certification. Even though Certificateless Public Key Cryptography (CLPKC) combines the appealing features of PKI [4] and IBC [5] it suffered from the Denial-of-Decryption (DoD) attack [2]. This led to the development of a new paradigm called Self-Generated-Certificate Public Key Cryptography (SGC-PKC) [2]. The SGC-PKC was based on the CL-PKC. The SGC-PKC satisfactory captures the DoD attack and it also proposed the maiden scheme derived from the novel application of Water’s Identity-Based Encryption scheme. This paper proposes a cryptographic protocol based on SelfGenerated-Certificate Public Key Cryptography. It gives the implementation details of the SGC-PKC scheme in Java and elucidates the necessary infrastructure needed to support the SGCPKC protocol. It also studies a prospective application of proposed protocol.
