密碼學(xué)的專(zhuān)業(yè)術(shù)語(yǔ)

密碼學(xué)是研究編制密碼和破譯密碼的技術(shù)科學(xué)。研究密碼變化的客觀(guān)規律，應用于編制密碼以保守通信秘密的，稱(chēng)為編碼學(xué)；應用于破譯密碼以獲取通信情報的，稱(chēng)為破譯學(xué)，總稱(chēng)密碼學(xué)。電報最早是由美國的摩爾斯在1844年發(fā)明的，故也被叫做摩爾斯電碼。它由兩種基本信號和不同的間隔時(shí)間組成：短促的點(diǎn)信號" ．"，讀" 的 "（Di）；保持一定時(shí)間的長(cháng)信號"—"，讀"答 "（Da）。間隔時(shí)間：滴，1t；答,3t；滴答間,1t；字母間,3t；字間,5t。
