Description

Lightweight low-orbit constellation networking authentication and group key negotiation method
Technical Field
The invention relates to a lightweight low-orbit constellation networking authentication and group key agreement protocol, belonging to the technical field of satellite communication and networking authentication.
Background
Firstly, the number of satellites in the low-orbit constellation network is relatively large, for example, 66 low-orbit satellites are shared in an iridium communication system, and 48 low-orbit satellites are shared in a global satellite communication system; meanwhile, the low-orbit constellation network has wide application, and the low-orbit satellite is widely used for detection and communication due to the close distance to the ground.
However, most of the existing satellite systems are composed of a single satellite. The current satellite networking in foreign countries is only an iridium satellite communication system and a globalstar communication system. Due to the fact that the low-orbit constellation networking is high in implementation and maintenance cost and high in implementation cost, a mature low-orbit constellation networking technology is not provided at present in China. Aiming at low orbit constellation networking, many domestic scholars research the authentication protocol of the low orbit constellation networking.
Because networking authentication needs to be frequently performed between low-orbit satellites in a low-orbit constellation network, a lightweight low-orbit constellation networking authentication protocol needs to be designed to meet the authentication requirement of the low-orbit constellation networking; because the transmission efficiency of the messages in the low-orbit constellation network is low, a protocol is needed to be researched to improve the transmission efficiency of the messages between the low-orbit satellites, namely a group key negotiation protocol; however, the low-orbit constellation network has the characteristics of high topology dynamic change and fast link switching, so the current authentication protocol is not suitable for low-orbit constellation networking. Meanwhile, for low-orbit constellation networks, the existing authentication protocol is not safe enough.
Disclosure of Invention
The invention aims to provide a lightweight low-orbit constellation networking authentication and group key agreement protocol aiming at the characteristics of high topology dynamic change and quick link switching of a low-orbit constellation network; the method specifically ensures the privacy of the message by using a symmetric key in the message transmission process, ensures the integrity of the message by using a message verification code, and ensures the high efficiency of transmission by using a group key negotiation protocol.
The purpose of the invention is realized by the following technical scheme.
A lightweight low-orbit constellation networking authentication and group key agreement protocol comprises three parts, namely a low-orbit constellation networking authentication process, a low-orbit constellation networking group key agreement process and a change on a message transmission mode after the group key agreement process is finished;
the symbols involved in the authentication process of the low orbit constellation networking are as follows:
the low-orbit constellation network consists of low-orbit satellites and low-orbit inter-satellite links and can be represented by a undirected attribute graph LUG (LV, LE);
wherein LV denotes a low-orbit satellite node, i.e. denotes a low-orbit satellite in a low-orbit constellation network, and is specifically expressed as<nLV，sLV，dLV>Wherein n isLVThe identification represents the number of the low orbit satellite and is the identification for uniquely identifying the low orbit satellite; sLVSecurity information representing low earth orbit satellites; dLVControlled information representing low earth orbit satellites;
LE denotes the low-orbit inter-satellite link, noted<lvm，lvn，sLE>Wherein lvm∈ LV is the start of the link LE, LVn∈ LV is the end point of link LE;
LS denotes a low orbit satellite gateway station, denoted<nLS，sLS，cLS>Wherein n isLSThe method comprises the steps of representing the serial number of a low-orbit satellite gateway station and uniquely identifying one low-orbit satellite gateway station; sLSSecurity information indicative of a low earth orbit satellite gateway; c. CLSControl information indicative of a low earth orbit satellite gateway;
the low earth constellation networking authentication process is responsible for satellite authentication in the following two cases. Firstly, when a satellite passes through a polar region intersection and then the satellites on adjacent two-side orbits change, a communication link between corresponding satellites needs to be switched; secondly, when satellites which are positioned on adjacent orbits but run in opposite directions need to communicate in the high latitude direction through the satellites on the same orbit and then jump to the adjacent orbits;
the low orbit constellation networking authentication process is realized by the following steps:
step one, low orbit satellite lviAnd low orbit satellite gateway station lskCarrying out authentication;
wherein, lviAnd a low orbit satellite to be networked outside the low orbit constellation network;
low orbit satellite gateway station lskA transfer station which is the ground outside the low orbit constellation network;
step two, after the authentication of the step one is completed, the low earth orbit satellite lviWill turn to the low orbit satellite gateway station lskTransmitting and low earth orbit satellite lvjThe authentication request of (1);
wherein, lvjIs a low-orbit satellite node in a low-orbit constellation network LUG ═ (LV, LE);
step three, low orbit satellite gateway station lskWill and low orbit satellite lvjCarrying out authentication; at the same time, the low orbit satellite gateway lskWill generate two low orbit satellite nodes lviAnd lvjA session key in between;
step four, when low orbit satellite gateway station lskAnd two satellites lviAnd lvjAfter passing the certification, the low orbit satellite gateway lskSending session keys to lviAnd lvj；
Step five, after the session key is sent, lviWill be added to the low orbit constellation network, which will increase with the low orbit satellite lviAnd low earth orbit satellite lvjAssociated Low-Earth inter-satellite Link leij；
And finishing the authentication process of the low orbit constellation network from the step one to the step five.
The low orbit constellation networking group key negotiation process specifically comprises the following steps:
step 1, taking low-orbit satellites on the same orbit as a group, taking low-orbit satellites on adjacent orbits as a group, and dividing all the low-orbit satellites into a plurality of groups according to the mode; lviAfter the low-orbit constellation network is added, the groups are distributed according to the above principle;
the number of the groups is more than or equal to 1, and the number of the groups is related to the satellite node scale of the low-orbit satellite network;
step 2, mixing lviCarrying out XOR calculation on the carried session key and all symmetric keys in the group to which the session key is added to obtain a new group key, and sending the group key to the low-orbit satellite gateway station by the group, so that the low-orbit satellite gateway station can maintain the keys of the groups;
so far, from step 1 to step 2, the low orbit constellation networking group key negotiation process is completed.
The change of the message transmission mode after the group key negotiation process is completed specifically includes:
before group key negotiation is realized, a corresponding symmetric key is used for decryption and encryption once when a communication message passes through each low-orbit satellite;
after group key negotiation is realized, communication messages are directly forwarded in a group, and after one group enters another group, a key of the other group is used for secondary encryption; the protocol transmitted at the same time adds the group through which the message passes in the message content, so that when the message reaches the low orbit satellite gateway station, the low orbit satellite gateway station uses the secret keys to decrypt in sequence according to the group through which the message passes.

2. the sequence number SQN is used for replacing a timestamp for synchronization, so that replay attack can be prevented under the condition of large satellite-ground transmission delay;
3. in the group key negotiation process, the satellite does not need to know the keys of other satellites in the group, so that the keys of other satellites cannot be leaked after the satellite in the call ticket is attacked, and only the group key negotiation needs to be carried out again;
4. through the performance test, the scheme is compared with the traditional public key scheme, and the following results can be obtained: the scheme has the authentication delay of 21.22ms at most, 11ms at most and the average delay of 14.02 ms.
