Exposure of private keys is the dangerous attack in the public key *** put forward an identity-basedparallelkey-insulatedproxysignature(IBPKIPS) scheme to deal with the problem of key exposure in the identity-basedproxysignature system. Our IBPKIPS scheme is secure withoutrandomoracles. In the IBPKIPS scheme, we use two different helper keys to renew the temporary private keys. Our IBPKIPS scheme is securer and more flexible than the identity-basedproxysignature scheme.
