Abstract
The present invention provides a method for realizing authentication mode compatibility between two kinds of mobile telephones in a personal hand-held system. A random number RAD generated by a user home register and an authentication evident code RESULTphone (64BIT) generated by the authentication algorithm of a mobile telephone authentication cipher stored by a mobile telephone itself respectively generate an authentication evident code RESULTfea 132 (64BIT) with a universal FEAL32 algorithm. The RESULTfea 132 is compared with an authentication evident code RESULTstephi generated by a universal STEPHI algorithm. As long as one authentication process is successful, the authentication is successful, and a system originally only supporting one authentication mode can simultaneously support two authentication modes of STEPHI and FEAL32. A PHS system utilizing the present invention can realize the compatibility of an FEAL32 and an STEPHI mobile telephone systems. As long as the existing systems are upgraded and reformed, the existing systems can support two authentication modes. The present invention establishes foundation for intercommunication among all manufacturer apparatuses for realizing PHS systems in future. Therefore, the present invention makes the progress that a PHS system simultaneously merges various mobile telephone apparatuses, and can effectively utilize the existing investment.

Fig. 3 is the schematic diagram about the FEAL32 algorithm.
Embodiment:
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 the inventive method flow chart.The main thinking of this method is to adopt the user attaching register to produce the authentication plain code RESULTphone (64BIT) of the mobile phone identification password authentication arithmetic generation of random number RA D and mobile phone storage itself, respectively with general FEAL32 algorithm generation authentication plain code RESULTfeal32 (64BIT), RESULTfeal32, general STEPHI algorithm produces authentication plain code RESULTstephi and compares, as long as an authentication is arranged to be passed through, just think that authentication passes through, make and originally only support a kind of system of authentication mode can realize supporting simultaneously STEPHI and two kinds of authentication modes of FEAL32, the PHS system of application this method can realize the compatibility for FEAL32 and STEPHI cell phone system.
System produces 64bit random number RA D by random number generator 101, the authentication password (202) of the 64bit that obtains then in system side, random number RA D and authentication password will generate 105RESULTstephi, 306RESULTfeal32 respectively respectively as the input parameter of 103STEPHI authentication arithmetic and 304FEAL32.Above step all is to carry out on the user attaching register of 111PHS system side.
System produces 64bit random number RA D by random number generator 101 will send mobile phone to by 113 radio paths, the resident authentication password 110 of mobile phone itself, and it is identical surveying authentication password 102 for its authentication password 110 of legal mobile phone with system.With the authentication password of RAD and mobile phone side input parameter, will generate an authenticating result as the mobile phone identification algorithm.
Authenticating result 205RESULTstephi, 206RESULTfeal32 that mobile phone side authenticating result 108 will be calculated with system side.Deliver to 107 base station controllers together.On 107 base station controllers, compare,, so just think that authentication passes through as long as 108 is identical with 105 or 108 and 106 identical.Certainly physical presence is a kind of possible, as adopts the mobile phone of a kind of FEAL32, is an illegal mobile phone, its generation 108 and 106 certainly inequality, but may with 105 coming to the same thing relatively, this chance exists, but consider that authenticating result is 64 bit, size is 10 19 powers.The probability that at every turn relatively has this chance is 10 19 powers.Might as well think that his life of disabled user of a PHS mobile phone reaches 100 years old, in this time of 100 years old, be approximately 100 * 365 * 24*60*60=3153600000 second, might as well suppose that he dialed a phone in per 10 seconds, he dials phone throughout one's life No. 315360000 times.So its authentication comparison probability of successful may to occur be 1/1000000000.So can think that the method for this realization authentication is very safe.
Fig. 2 is the algorithm schematic diagram of STEPHI.System produces 64bit random number RA D by random number generator 201, the authentication password (202) of the 40bit that obtains then in system side, and random number RA D and authentication password are as 203STEPHI authentication arithmetic input parameter.Two input parameters carry out computing through the STEPHI algorithm, and the 204th, the authenticating result RESULTstephi that process STEPHI algorithm obtains.
Fig. 3 is the algorithm schematic diagram of FEAL32.
System produces 64bit random number RA D by random number generator 301, the authentication password 302 of the 64bit that obtains then in system side, and random number RA D and authentication password are as 303 FEAL32 authentication arithmetic input parameters.Two input parameters carry out computing through the FEAL32 algorithm, and the 304th, the authenticating result RESULTfeal32 that process FEAL32 algorithm obtains
In sum, the invention discloses a kind of PHS system and realize compatible FEAL32 simultaneously, the method for two kinds of mobile phone standards of STEPHI.Adopt this method, can improve existing systems very easily, make and originally only support a kind of system of authentication mode can realize supporting simultaneously STEPHI and two kinds of method for authenticating of FEAL32, like this for the mobile phone that possesses FEAL32 or STEPHI algorithm that has existed in the market, need not divide mobile phone to adopt which kind of authentication mode, thereby make mobile phone in the system of two kinds of authentication modes, intercommunication to use in the mobile phone proparea that networks.This kind is convenient to exploit market to the compatibility of mobile phone authentication mode, and simultaneity factor is supported the authentication of dual mode, also is convenient to realize the intercommunication of the variant PHS of equipment vendors system interconnect.
