可以说,当前互联网上有超过90%的加密连接(包括SSL握手),都依赖于RSA-2048。同时,RSA也被用于验证数字签名,推送固件更新、以及验证电子邮件等日常工作与任务中。 可见,问题在于:密钥长度大小的增加,并没有成比例地提高其自身的安全性。虽然RSA-2048比其前身增强了40亿倍,但是RSA-3072仅增强了65k倍左右。实际上,对...

And there is no acceptable argument for 2048/3072 vs 4096 bits (only a very small speed overhead). 3072 bits can lead to compatibility problem if user agent hardcode some key sizes (2048 and 4096 bits will be better supported than 3072). Worst, argument of the 90 days key regeneration ...

For example, a 3072-bit RSA signature provides the same level of security as a 256-bit ECDSA signature. 3.4. Speed ECDSA runs faster than RSA. It also requires significantly less memory. This is a particularly important property for use in mobile devices increasingly requiring secure communication...
