Process for securing the execution of a mobile code in an untrusted environment

Molva, Refik;Loureiro, Sergio
Patent N°EP1065593

A process is disclosed for securing the execution of a mobile code in a Information Handling System (I.H.S.) (30) having a function which can be represented on a matrix F . The function is being encrypted by means of an Error-Correcting Code (E.C.C.) transformation, where the code is preferably a GOPPA code. The transformation produces an encrypted matrix F' = FGP + E, where G is a generating matrix for an (n, k, d) algebraic block code C, P is a nxn random permutation matrix and E a kxn random matrix where at least n-t columns consists of a null vector. Since the Encrypted matrix F' is still a matrix, the mobile code which is encrypted is still executable in a user's environment.
