摘要： An authentication method authenticates between subscribers of a communications system using an asymmetric elliptic curve encryption algorithm. The method involves providing a first and at least one second subscriber having a first or second secret key known only to the respective subscriber and a public key; authenticating an inquiry transmitted by the first subscriber with respect to the validity of the first certificate contained therein and associated with the first subscriber; calculating the response of the second subscriber associated with the inquiry; randomized encryption of the calculated response and a second certificate associated with the second subscriber using the public key; decryption and authentication of the response transmitted by the second subscriber with respect to the validity of the second certificate contained therein.

摘要： A method for authentication and identification uses different keys for the prover and the verifier, but on the other hand dispenses with the utilization of long number modulo arithmetic by the use of simple basic components such as, for example, arithmetic operations in finite bodies GF(2n). A private key is stored in the prover, so that the latter can receive, in encrypted form, data elements generated as random elements and can itself utilize them again as key for an authentication method of a data set to be transmitted. The verifier receives the authenticator thus formed and checks it. If the data set is generated by the verifier and transmitted to the prover, then this method can serve for the identification of the prover. The method is particularly advantageous in the area of smart cards, since there the required space in the hardware implementation can be considerably reduced.

摘要： In a data transmission method for a tachograph system, digital messages are transmitted between a speed transmitter (MS) and a recording unit (RU). The digital messages contain a pair of keys including a public key (KMP, KRP) and a private key (KMS, KRS), as well as a certificate (ZM, ZR) derived from the respective pair of keys. The public keys (KMP, KRP) and the certificates (ZM, ZR) are mutually verified between the recording unit (RU) and the speed transmitter (MS). If the verification is positive, the speed transmitter (MS) detects sensor data, and a digital message is generated therefrom. In addition, the speed transmitter (MS) generates authentication data for the message in accordance with the pair of keys (KMP, KMS) thereof. The message and the authentication data are transmitted to the recording unit and are processed there in accordance with a validity of the authentication data verified by the recording unit (RU).

摘要： The invention relates to an encoding method for identifying a subsequential manipulation of a counter meter reading consisting, when the counter reading is increased or decreased, in activating the computation of a new encoded meter reading and in calculating a new encoded meter reading by applying a forward chain one-way function to the encoded meter reading, wherein a complex variable domain of said forward chain one-way function is included into the antecedent domain thereof. The invention also relates to a method for verifying the authenticity of a counter meter reading consisting in subtracting test meter readings based on the meter reading for obtaining the number of tests, in producing an encoded test meter reading by applying the chain one-way function to the encoded meter reading, in applying the chain one-way function with the number of tests and in comparing the test meter reading with the final encoded meter reading and, if the test meter reading defers from the final encoded meter reading, a negative status signal is emitted. An encoding system for carrying out said encoding method and a verification system for carrying out the verification method are also disclosed.

摘要： Applying both an encryption and also a decryption algorithm, which is inverse to the encryption algorithm, as an encryption definition to thereby enable the use of an encryption unit and a decryption unit of an encryption/decryption device simultaneously, i.e. temporally overlapping, in an encryption process when a part of the data to be encrypted is supplied to the encryption unit while the other part is supplied to the decryption unit. The result is encrypted data or is a cipher text, respectively, whose parts are only “encrypted” in a different way. During decryption, it only has to be guaranteed by suitable regulations that those parts which were encrypted by the encrypted unit are again decrypted by the decryption unit, while the other parts which were “encrypted” by the decryption unit are “decrypted” by the encryption unit.
摘要翻译：将与加密算法相反的加密和解密算法应用为加密定义，从而能够在加密中同时使用加密/解密装置的加密单元和解密单元，即时间上重叠当将一部分要被加密的数据提供给加密单元，而另一部分被提供给解密单元时，处理。结果是分别是加密数据或密文，其部分仅以不同的方式“加密”。在解密过程中，必须通过适当的规定来保证被加密单元加密的部分再次被解密单元解密，而由解密单元“加密”的其他部分由加密“解密” 单元。
