摘要

Method and arrangement the Pope manage generations of information security code in an environment of information, and.Entities consumer and production security code in an environment of information ".The invention generally relates to the management of generations of cryptographic code in an environment of information comprising a hand producer of code generating and distributing information codeGo to one side of the consumption of the code.A basic concept of the invention is to define, by means of a function of the derivation of code via only predetermined, a relationship between generations of codes.In such a way that previous generations of codes may be efficiently derived from recent, but not otherwise.A basic idea according to the invention is therefore, to replace the code update.Code information of a code generation more ancient by the code information of the new generation of code, on the side of the consumer code.Where necessary, the consumption of code to apply interactively.The function of derivation of code of single path set to derive code information of at least one generation older code from the code information of the new generation of cu00f3digO. thus, the storage requirements on the side of the consumption of code may be significantly reduced.
