Embodiment 1
Signal referring to Fig.1~2, in order to realize that Verification System can weigh security privacy and the system expandability, this reality
The anonymous group technology that example proposes a kind of Verification System is applied, this method is applied in expansible RFID authentication protocol, it is made
Suitable for medical system, and there is the harmony between good privacy and scalability.Wherein RFID, that is, radio frequency identification is one
The contactless automatic identification technology of kind, it can rapidly carry out item tracing by radiofrequency signal automatic identification target object
And data exchange, and identify that work without manual intervention, is operable with various adverse circumstances.RFID technique can recognize high-speed motion
Object simultaneously can identify multiple labels simultaneously, swift and convenient to operate.During RFID technique is born in World War II, it is to pass
The successor of system barcode technology, also known as " electronic tag " or " RF tag ".The present embodiment is based on anonymous group technology building
Secret protection RFID rapid authentication agreement, which is suitable for medical field, realizes security privacy and the system expandability
It is balanced.
Further, the Verification System of the present embodiment meaning, for example including application scenarios below: assuming that be each hospitalized
Patient is sent the RFID electronic label of a wrist strap, preserves the essential information of some patients such as in electronic tag: identity letter
Breath, drug allergy history etc. are additionally stored with the information for system authentication of initialization distribution.Medical staff distributes one and reads
Device is read, the therapeutic state of the affiliated patient of label is obtained, for example whether take medicine, regular ward round etc. on time.In urgent feelings, can mark
It signs in reading range under request label condition, is carried out even if obtaining the information such as medical history, the allergies of patient by acquisition authenticating tag
Sue and labour.The Verification System relates generally to three entities, respectively manager, reader and label.Manager mainly initializes
Each label, and be each group of transmission group code key and logo collection, furthermore manager also wants authorised reader to access label；And it reads
It reads device and label is to realize two entities being mutually authenticated；The process of authentication protocol is broadly divided into two stages, initial phase
And authentication phase；The participant of initial phase is manager, reader, label, and authentication phase only has reader and label ginseng
With.
Based on the above-mentioned Verification System suitable for medical system, a kind of anonymous group technology is provided, and same by obscuring
The mode of one anonymous group session mark, guarantees that the message generated in verification process has the unidentifiable property towards attacker, from
And realize secret protection.The size divided by adjusting anonymous group, may be implemented the equilibrium between secret protection and scalability,
In face of different scene demands, it is big that different anonymous groups is set；Such as under the relevant scene of patient, to increase privacy performance,
The size that anonymous group should be improved can reduce the size of anonymous group in medical instrument management, improve rapidity；In addition, the association
View can prevent the common security threats such as tracking attack, impersonation attack, Replay Attack.
Grouping refers to being grouped label, and the example of list illustrates the validity of grouping, and current each label only has
One oneself name, has a name for identical group after grouping, you will look for a label, Ke Yixian in the case where doing so
Group is found, then finds specific label, the time can be shortened.But simple this grouping, it can be dangerous.Attacker is easy to obtain
Take the relevant some information of group, such as group code key (group interior label is shared, so easily leakage).Grouping of the invention is to attack
The person of hitting gets a group code key, and safety.Be related to two kinds of defence policies: label each first stores a mark subset,
Certification can randomly choose a mark from subset every time, in addition, there is a situation where to share between our mark subset, play
One purpose obscured, even if attacker gets the mark, but he not can determine that it is that member in group.For label
Grouping, reader will store relevant group information, all group code keys and each group of identification sets etc., belonging to label will store
The group code key and mark subset of group, and identifying subset is selected from the identification sets that reader stores.
Further, which belongs to the initial phase of authentication protocol.Specifically, further including following step
Suddenly, the operation that label is initialized by administrator including the division organized and carries out a group code keyUnique code keyIdentification sets Ωi,jDistribution；By each group of corresponding a kind of illness, itself an illness information will be assigned when patient is medical
Relevant wrist strap RFID label tag, same type of patient will be divided into the same anonymous group GiIt is interior.
N number of label is divided into τ group in system, and every group possesses unique group keyThe group key is owned in group
Label is shared, while organizing GiIn each group membership TjIt is assigned a unique certification code keyEach set of tags GiIt is transported to
One logo collection ξi={ IDi,1,IDi,2,...,IDi,M, intersection is not present in any different group identification sets, i.e.,
GiIn each label possess the identical identification sets of mark quantityΩi,jFor ξiSon
Collect, there must be the mark shared with other members in the mark subset in label.Manager distributes each group of secret information
SetTo reader, σiFor ξiThe mappings of middle identification setsi={ IDi,x,πx| 1≤x≤M }, wherein πxIt is
Expression and IDi,xAssociated label code key includes mark ID that is, in the sub-mark set of all labels storagei,xLabel
Unique code key formed set, when any one label does not all include IDi,xWhen πxFor empty set.Therefore the stage is related to authenticating
System initialization, manager have been substantially carried out the division of group and the distribution of the attribute data for certification.
For the anonymous group technology proposed in initial phase, more specifically, the division and system authentication of anonymity group
The distribution of parameter the following steps are included:
The division of anonymity group: assuming that there is N number of label in system, label is divided into τ group, each group of label by manager
Number isPreferable time complexity is able to maintain in this step: agreement can be realized the quick identification of label, it is assumed that
The scale of label is N in system, in traditional authentication schemes, to traverse the record of all labels of verifying end storage, system is recognized
Card complexity is o (N).In the method, the time complexity for first having to find the cost of corresponding group of needs of label is
The division that the time complexity that corresponding label is spent depends on identification sets is found from group, it is assumed that current authentication label after division
In xth group, it is assumed that some identifies corresponding πxMiddle code key number is that the time complexity that k then needs is o (k).Therefore, total to answer
Miscellaneous degree isDue toAnd with the increase of N, this gap of increase for organizing scale be will increase, the group technology
The time can effectively be shortened.
Code key distribution: i-th group of label is Gi(i ∈ 1 ... τ }) it is that manager distributes one group code keyTo GiGroup,
The code key is organized interior all members and is shared.To GiEach group membership TjDistribution one unique certification code key
The distribution of logo collection: manager sends a logo collection, G to each set of tagsiThe logo collection of group label
For ξi={ IDi,1,IDi,2,...,IDi,M, wherein joining M number for system, intersection is not present in any different two groups identification sets, i.e.,And i, j ∈ 1 ... τ }.
The distribution of group member's sub-mark collection: GiIn each label own an element the identical identification sets of quantityEach element is different in set.Same mark
Multiple labels may be organized together to share, i.e.,And p ≠ q.It therefore can be by
It is shared to depend on initial phase, if the mark is distributed to a group membership, if shared to have one for attacker
Fixed uncertainty, by this thought obscured, it is unique that attacker, which can not determine that this is identified whether,.
Reader code key generates: manager distributes each group of secret information setTo reader,
σiFor ξiThe mappings of middle identification setsi={ IDi,x,πx| 1≤x≤M }, wherein πxIt is to indicate and IDi,xAssociated label code key, i.e.,
In the sub-mark set of all labels storage, include mark IDi,xLabel unique code key formed setWhen any one label does not all include IDi,xWhen πxFor empty set.
Anonymity group technology provided in this embodiment also has the advantage that
Secret protection: it when attacker is a certain group membership or by illegal channels gets a group code key, can be solved based on this
Internal mark ID outi,jx, however due to IDi,jxMay be to be shared by group member, attacker can not be determined as group in that
The mark that a member generates, so that member identities can not be distinguished.Further the member of identical illness is divided into one group by us, at
The information of member has equity, and the group key that member shares is not easy to be compromised away, and the group member for leaking group key is same
It will cause the hidden danger of the privacy leakage of itself.
Safety: assuming that attacker wants personation label, not identifying corresponding code key, can not generate legal message V,
At reader end, suitable code key can not be found and decrypt illegal message V.In addition, U, V are equal using the parameter inside symmetric cryptography
Have a random number participation, ciphertext be it is random uncertain, cannot achieve tracking attack.Same attacker can not also implement to reset
Attack, due to every wheel certification request, the random number that reader is sent is different, with the current response of previous message back, is readding
Reading device end can not find suitable code key and be decrypted.
Harmony between privacy and scalability: assuming that the group membership's quantity for sharing some mark is k, then with group
Scale increases k value and will also increase, and the secret protection degree of user can improve.It equally will cause authentication efficiency as k is worth increasing
Decline, by adjusting the adjustable k value of size of division group scale, thus the problem of balanced secret protection and efficiency.Due to recognizing
The time complexity of card is the scaling concern that linear authentication efficiency determines system scale, and therefore, which may be implemented
Equilibrium between privacy and scalability.
