SECURITY MODULE COMPRISING A VOLATILE MEMORY FOR STORING AN ALGORITHM CODE

摘要

The invention relates to a security module (100) for use with a terminal. The security module comprises a data interface (110), which can be coupled to a terminal and which is provided for receiving at least one portion of an algorithm code or the entire algorithm code from the terminal. The security module also comprises a power interface (120) for receiving supply power. A volatile memory (130), which is coupled to the power interface (120) in order to be supplied with power, stores the portion of the algorithm code or the entire algorithm code that is received via the data interface. A processor (140) executes the algorithm code in order to obtain an algorithm code outcome that can be supplied to the terminal. The algorithm code of the security module (100) is effectively protected from spying conducted by a potential hacker due to the storing of at least one portion of an algorithm code in the volatile memory (130) of the security module (100) as described by the invention.
