Abstract

A very long cryptosequence stored on the sender side is used to create a unique encryption sequence, which is used to encrypt a digital information sequence, so that it can be transmitted over a non-secure network (11). Prior to encryption, a unique synchronisation pattern is inserted into the digital information sequence, the pattern being related to the stored cryptosequence and the personal identity of the sender. A unique decryption sequence is created on the receiving side, and this contains a receiver identity related to a users personal identity (7). Successive decryptions are carried out with the aid of data sent to the receiving side on portable data storage media (21) via a separate, secure route (22) and then stored on the receiving side so that they can be used to carry out successive analyses to check whether the inserted synchronisation pattern corresponds to the synchronisation pattern created from data stored on the receiver side. If the patterns match, the received sequence is decrypted and once the synchronisation pattern has been removed this sequence will be the same as the original digital information sequence, apart from it being modified with the receiver identity. At the same time, the synchronisation pattern created on the receiver side will contain the sender identity.
