The present invention is related to a method of securing integrity and authenticating origin and privileges of a piece of code. According to the invention, a method of securing integrity and authenticating origin and privileges of a piece of code in a communication network by digitally signing said piece of code, is characterized by the steps of: providing an aggregator (C), which is a holder of a valid signing certificate, -submitting a developer material to the aggregator, inserting a revocation code into the developer material, building a complete piece of code using the developer material and the revocation code, digitally signing the complete piece of code using the certificate held by the aggregator, making the digitally signed complete piece of code retrievable to the holder (B) of the developer material, providing a server (C2) for authenticating privileges of the digitally signed complete piece of code, -executing the revocation code and checking with the server whether the privileges of the digitally signed complete piece of code have not been revoked. |
