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 (CL-PKC) 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 Self- Generated-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 SGC-PKC protocol. It also studies a prospective application of proposed protocol.
