non-degenerate, i.e. G is the generator of G, ek(G, …, G, …, G) is GkA generator of (2);
the commutative law is satisfied, i.e., the k original image inputs can commutate the positions arbitrarily.
Specifically, the method for constructing the multi-linear mapping function family in this embodiment includes, but is not limited to, discrete logarithm, elliptic curve, and the like.
S02: generating a system master key;
specifically, the key of the key control center is a system master key, which is generally generated by cloud computing or server settings, and the system master key may be denoted as MSK = s, and correspondingly, the system public key is PK = gsThe system public key is public, and can be inquired through a bulletin board, and can also be broadcast by using a public channel, and the system master key is secretly stored by the key control center.

S05: and calculating by taking each hash function mapping value as a base number and a system master key as an index to obtain a private key corresponding to each participatable object, and sending the private key to the corresponding participatable object through a secure channel so that the participatable object sends out a temporary public key when participating in a session, determines a session key by using a multilinear mapping function family according to the private key of the participatable object and the temporary public keys of all other actual participated objects, and establishes an encrypted communication channel by using the session key.
It is understood that in a communication system of cellular car networking cooperative communication, the participatable objects include: one or more intelligent automobiles, and/or one or more road side units, and/or one or more cloud servers. The number of the intelligent automobile, the roadside units and the cloud servers can be set according to actual conversation requirements, participatable objects participating in the conversation are actual participated objects, and two or more participatable objects are inevitably present during each conversation participation, such as one intelligent automobile and one roadside unit, or three intelligent automobiles, two roadside units and one cloud server.
Specifically, the private key of each participatable object can be represented as SKID_i=gID_i sAnd sending the data to the corresponding participatable object by using a non-public secure channel, and if the participatable object participates in the session, generating a session key by using the private key and other numerical values.
Specifically, any actual participating object may use its own private key and temporary public keys of all other actual participating objects as original images to input, and determine a session key by itself using a multi-linear mapping function family, assuming that k actual participating objects are in a certain session, the session key of the ith actual participating object may be expressed as:
K_i=ek(gID_1 r_1,…, gID_(i-1) r_(i-1)，SKID_i, gID_(i+1) r_(i+1),…, gID_k r_k)r_i，
gID_1 r_1the temporary public key sent out for the first actual participating object may be expressed in a form of taking the hash function mapping value thereof as a base and r _1 as an exponent, r _1 may be a temporarily generated value, so as to calculate the temporary public key, or a temporary public key whose value may be expressed as above may be directly generated, and r _1 is not a primary necessary value. The temporary public keys of other actual participating objects and so on.
From the above properties regarding the family of multilinear mapping functions, the following reasoning can be derived:
K_i=ek(gID_1 r_1，…, gID_(i-1) r_(i-1)， SKID_i, gID_(i+1) r_(i+1),…, gID_k r_k)r_i
= ek(gID_1，…, gID_(i-1)， gID_i, gID_(i+1),…, gID_k)r_1*…*r_k*s

s12: generating a temporary public key and broadcasting;
further, the step S12 of generating and broadcasting the temporary public key may include:
generating a temporary value which is stored in a secret way;
and calculating by taking the self hash function mapping value as a base number and the temporary numerical value as an index to obtain a temporary public key and broadcasting.
For the ith actual participant, the temporary value is r _ i, and the temporary public key is gID_i r_iBesides the method for generating the temporary value and then calculating the temporary public key, the step of generating the temporary value can be skipped to directly generate a temporary public key, as long as the temporary public key is ensured to satisfy a form which can be expressed as an exponential power, and the form ensures that session keys of all actual participating objects are consistent.
S13: receiving temporary public keys of other actual participating objects;
s14: determining a session key by utilizing a multi-linear mapping function family according to a private key of the session key and temporary public keys of all other actual participating objects;
specifically, assuming that there are k actual participating objects in a session, the session key of the ith actual participating object can be expressed as:
K_i=ek(gID_1 r_1,…, gID_(i-1) r_(i-1)，SKID_i, gID_(i+1) r_(i+1),…, gID_k r_k)r_i。
due to the characteristics of the family of multilinear mapping functions, it can be derived:
K_i=ek(gID_1 r_1，…, gID_(i-1) r_(i-1)， SKID_i, gID_(i+1) r_(i+1),…, gID_k r_k)r_i
= ek(gID_1，…, gID_(i-1)， gID_i, gID_(i+1),…, gID_k)r_1*…*r_k*s
therefore, K _1= K _2= … = K _ K, i.e., all session keys generated by the actual participating objects are consistent, so that a secure encrypted communication channel based on a symmetric cryptographic algorithm can be constructed.
S15: an encrypted communication channel is established using the session key.
Further, after the encrypted communication channel is established by using the session key, the method further includes:
and after the session is ended, destroying the temporary public key.
Further, after the encrypted communication channel is established by using the session key, the method further includes:
updating temporary public keys of other actual participating objects;
and updating the session key according to the updated temporary public key by utilizing the multi-linear mapping function family.
It can be understood that due to the characteristics of the multi-linear mapping function family, if other actual participating objects in the current session are changed, the session key does not need to be completely calculated again, and the session key can be updated according to the temporary public key of the changed actual participating object on the basis of the original session key, taking n actual participating objects added in the current session as an example, the new session key of the current actual participating object is: k' _ K = ek+n（K_k,…,gID_(n-1)，g ID_n) And K '_ 1= K' 2= … = K '_ K = … = K' _ K + n,
wherein, K' _ K is the updated session key, and K _ K is the original session key when not updated.
Re-interaction, authentication and repeated calculation are not needed during updating, so that resources and time consumption are greatly reduced.
In the embodiment, the private key control center further determines the session key by using the private key according to the private key distributed by the hash function mapping and the multi-linear mapping function family, and the session key is quickly calculated and determined by using the characteristics of the multi-linear mapping function family, so that session participants are allowed to be quickly updated, the adaptability of cooperative communication is high, and the high requirements of the cellular internet of vehicles on flexibility, timeliness and availability can be met.

a memory for storing a computer program;
a processor for implementing the steps of the registration method of cellular internet of things cooperative communication according to any one of claims 1 to 3 or the session method of cellular internet of things cooperative communication according to any one of claims 4 to 7 when executing the computer program.
10. A readable storage medium, characterized in that the readable storage medium has stored thereon a computer program which, when being executed by a processor, realizes the steps of the registration method of cellular internet of things cooperative communication according to any one of claims 1 to 3 or the session method of cellular internet of things cooperative communication according to any one of claims 4 to 7.
