摘　　要：针对基于基本数字签名的涉密群组准入方案不能很好地保护申请者的隐私信息,提出一种基于椭圆曲线ElGamal密码体制的有向签名方案,并将该方案应用于涉密群组的准入机制,提出一种基于有向签名的涉密群组准入方案。通过与椭圆曲线ElGamal加密算法和ECDSA数字签名算法的比较分析,结果表明基于有向签名的涉密群组准入方案在保证安全的条件下既保护了申请者的隐私又节省了计算资源。According to the admission scheme for confidential group based on basic digital signature can not efficiently protect the private information of requester, a directed signature scheme based on elliptic curve E1Gamal cryptosystems is proposed, and apply it to the admission control for confidential group, and propose an admission scheme is proposed for confidential group based on directed signature. Through comparing to elliptic curve E1Gamal encryption algorithm and ECDSA algorithm, we show that our admission scheme for confidential group based on directed signature not only protects the private information of requester but also saves computing resources in the condition of security assurance.
