Abstract:
1. A packet security method of a packet security apparatus comprising: detecting, by the packet security apparatus, a plurality of features of a packet to be transmitted; determining, by the packet security apparatus, whether the detected plurality of features include a designated security level for the packet; determining, by the packet security apparatus, a security level of the packet according to the designated security level if it is determined that the detected plurality of features include the designated security level; determining, by the packet security apparatus, the security level of the packet according to the detected plurality of features if it is determined that the detected plurality of features do include the designated security level, wherein the security level of the packet is determined based on taking steps according to each of the plurality of features if it is determined that the detected plurality of features do not include the designated security level; determining, by the packet security apparatus, whether a first algorithm corresponding to the determined security level of the packet exists in a security tool database; and generating, by the packet security apparatus, a security packet according to the determined security level, wherein the security packet is generated using a second algorithm corresponding to a security level nearest to the determined security level when the first algorithm corresponding to the determined security level does not exist in the security tool database, wherein the plurality of features of the packet include at least one of a destination address of the packet, a transfer protocol of the packet, a packet size, and the designated security level for the packet.
