Looking for maker who can supply high quality of carbon steel and stainless steel butt welding fitting per ansi standard 我們正在尋找可以提供高品質(zhì)鉛鋼和不銹鋼焊接設(shè)備的供應(yīng)商
We have purchased and installed testing equipment in our testing room to meet ansi standards . we are also carrying through the iso9001 : 2000 quality management system requirements and will get the approval soon 在生產(chǎn)自動化方面我們不惜投入,擁有世界先進(jìn)水平的精密型鹽水噴霧試驗機(jī)鎖具耐用度測試儀表面粗糙度測試儀等檢測設(shè)備,可按美國ansi檢測標(biāo)準(zhǔn)檢測。
The elliptic curve digital signature algorithm ( ecdsa ) is the elliptic curve analogue of the digital signature algorithm ( dsa ) . it was accepted in 1999 as an ansi standard , and was accepted in 2000 as ieee and nist standards . unlike the ordinary discrete logarithm problem and the integer factorization problem , no subexponential - time is known for the elliptic curve discrete logarithm problem . for this reason , the strength - per - key - bit is substantially greater in an algorithm that uses elliptic curves 橢圓曲線數(shù)字簽名算法( ecdsa )是數(shù)字簽名算法( dsa )的橢圓曲線對等。它先后成為ansi , ieee , nist和iso的標(biāo)準(zhǔn),而且其它的一些組織正在考慮成為其標(biāo)準(zhǔn)。不象普通的離散對數(shù)問題和因數(shù)分解問題,橢圓曲線離散對數(shù)問題沒有已知的亞指數(shù)算法,所以使用橢圓曲線的算法在密鑰的位強(qiáng)度是足夠高的。
