基于椭圆曲线密码体制的广播多重数字签名算法

Based on the elliptic curve cryptography broadcasting multi-digital signature algorithm

基于椭圆曲线密码体制的多重数字签名算法主要体现在密码强度、加/解密的运算速度以及存储开销上有较大优势,能用较短的密钥实现较高的安全强度,提出的算法克服以往因运算比较复杂而导致数字签名验证速度不佳的情况,在算法中减少了原来广播多重数字签名方案中相对复杂的乘法及点乘运算,避免了求逆运算,提高了验证速度的同时,又不影响签名的安全性。

Based on the multiple elliptic curve cryptography digital signature algorithm reflected in the password strength, encryption / decryption of the computing speed and storage greater advantages, the key can be used to achieve higher short security strength. The proposed is mainly costs have algorithm for more complex operations overcomes the previous result by a digital signature verification rate of poor conditions in the algorithm to reduce the original multi-broadcast digital signature scheme is relatively complex multiplication and point multiplication, avoiding the inversion to improve the verification speed, at the same time, without affecting the security of the signature.
