字母组合法:“sigma”可以拆分为“sig-ma”,其中“sig”可以看作“sign”(符号)的前缀,帮助记忆它是希腊字母,而“ma”可以联想为“数学”(mathematics)的缩写,因为sigma在数学中常用。 谐音法:“西格玛”,这是sigma的常见中文音译,通过谐音帮助记忆。 故事法:想象一个科学家在研究数据时,发现了一组数据的离散程度...
As we have seen in the last section, the sigma symbol in math is ∑ which is pronounced as "sigma". This is one of the Greek alphabets. This sigma symbol is also known as "capital sigma". The summation notation written using the sigma symbol is also known as a "series" as it ...

We present the SIGMA family of key-exchange protocols and the “SIGn-and-MAc” approach to authenticated Diffie-Hellman underlying its design. The SIGMA protocols provide perfect forward secrecy via a Diffie-Hellman exchange authenticated with digital signatures, and are specifically designed to ensure...
