ECC的优缺点​​:密钥长度短,安全性高​​
同等安全强度下,ECC的密钥长度仅为RSA的1/6。例如,256位的ECC密钥安全性相当于3072位的RSA密钥。
基于椭圆曲线离散对数问题(ECDLP),数学复杂度更高,破J难度更大。
性能高效​​
加密/解密速度更快,CPU和内存占用更低,适合资源受限场景(如移动设备、物联网)。
网络传输消耗更少,尤其在密钥交换环节(如TLS握手)能减少流量开销。
​​前向安全性(Forward Secrecy)​​
结合ECDH算法时,每次会话生成临时密钥,即使长期私钥泄露,历史通信仍安全。
​​缺点:​​兼容性有限​​
老旧设备(如Android 2.3、Windows XP)可能不支持ECC证书。
部分协议(如某些邮件系统)尚未完全适配ECC。
​​实现复杂度高​​
椭圆曲线数学原理复杂,算法实现难度高于RSA。

​​RSA的优缺点​​:广泛兼容性​​
几乎所有系统和协议都支持RSA,包括老旧设备和传统应用场景。
适用于需要向后兼容的场景(如旧版TLS协议)。
​​功能多样​​
支持加密、数字签名和密钥交换,应用场景更广泛。
公钥分发机制成熟,便于集成到现有安全体系(如SSL证书)。
​​缺点:​​密钥长度长,效率低​​
为保证安全性需使用长密钥(如2048位及以上),导致计算速度慢、存储和传输成本高。
在资源受限环境中性能表现较差。
​​缺乏前向安全性​​
若私钥泄露,所有历史加密通信均可被解密。
TLS 1.3已弃用RSA密钥交换,推荐使用ECC等支持前向安全的算法。
​​量子计算威胁更大​​
RSA基于大数分解问题,易受Shor算法攻击,而ECC过渡到抗量子算法的成本更低
