Compact Leakage-Free ID-Based Signature Scheme with Applications to Secret Handshakes |
Abstract | ||
|---|---|---|
an important approach to resist the threat of key leakage, key insulated security allows secret keys to be periodically updated by using a physically-secure but computation-limited device. Recently, key insulated mechanism has been introduced into identity based (ID-based) signature to solve the key-leakage problem in ID-based signature scenarios. In this paper, we present two compact ID-based key-insulated signature schemes that try to minimize the total amount of message and signature. Compared with the up-to-date ID-based key-insulated signatures, our schemes enjoy the minimum net bandwidth and computation overhead. We also provide formal security proofs of our schemes under the Computational Diffie---Hellman assumption in the random oracle model. We focus on potential applications of our schemes to secret handshakes, but we believe they will find many other applications as well. |
