DES ALGORITHM-BASED ENCRYPTION METHOD |
摘要 |
<p>Applicable in communications systems in the sending of data among user equipment of nodes connected to a network. It is characterised in that it comprises generating random keys (6) that are different for each packet, which are used for enciphering each packet by means of the DES enciphering algorithm, and the sending in the header of the packet of that random key (6), in turn enciphered (9) by means of a more secure algorithm than the DES algorithm, which permits improvement in the security of transmissions on a non-secure medium to which are connected the nodes and user equipment of a telecommunications system using the procedure of the invention instead of the DES enciphering algorithm.</p> |
