Особенности программной реализации вычисления контрольной суммы CRC32 на примере pkzip, Winzip, Ethernet

Abstract

Обсуждаются алгоритмы вычисления контрольной суммы CRC32. Проанализированы описанные в литературе алгоритмы. Из имеющихся в свободном доступе исходных кодов восстановлен алгоритм вычисления контрольной суммы CRC32, который применяется на практике (в PKZIP, WinZIP, ETHERNET). На примере показано, что алгоритм, описанный в литературе и применяемый на практике, дают разные контрольные суммы.
