ID-based efficient and proactive threshold proxy signature in the standard model
摘要
Abstract
The security of existing identity-based threshold proxy signature schemes were almost proven in the random oracle model, and each proxy signer's proxy signature key was fixed in the valid period. A(t, n) ID-based proactive threshold proxy signature scheme (IBTPTS) was presented by using the publicly verifiable secret sharing technology, based on existential identity-based signature scheme. The scheme was proved to be safe in the standard model. Each proxy signer's proxy signature key can be updated regularly, and proxy signature verifying procedure only needs const bilinear pairings. Therefore the scheme has better dynamic security and higher efficiency.关键词
