That`s the way my problem is. I generated keys on the map and the pages of the terminal. I have on the side of the terminal the map of public and private keys and the terminals of public and private keys, and the same on the page of the card (I do tests, so that`s why I have them all on the terminal and on the map). If I generate KeyAgreement (terminal side) for the card as private and for the terminal as private, the sects are the same, so the generation is OK and I get a secret of 24 bytes (192 bits). If I generate the secrets on the map (2 cases as on the terminal) the secrets are also the same, but they are shorter – 20 bytes (160 bits). These are the ration codes. Terminal: I sat down and took the time to adapt rsa cryptographic functions for traditional DH a-ECC functions and you`ll find the open source app code here (github.com/ASKGLab/DHApplet/blob/master/src/dhapplet/DH.java). Note that the amount of RAM available in the RTR and the non-current DTR may be influenced by other applets as a watch. This means that the current applet, which uses the RTR and the non-current DTR, may fail when more applets are installed on the card. I haven`t created the APDU commands yet to create a complete arrow demo, but I think if you study the DH.java codes, that should be more than enough to give you a head start.

I`ve included a lot of praise in the source code to adapt it to different scenarios and the thought process, including designing the whole DH class and its importance. 2. The available DTR space (clear-on-delect) of the current logic channel. This version provides an implementation of basic security and cryptography classes. These implementations are supported by: . Post by sandeepkkamishetti ” Thu Jul 21, 2016 9:18 on the pseudo-annoan-annedable number generator with a 48-bit seed modified with a linear congruent formula. There is a problem with the implementation of KeyAgreement.ALG_EC_SVDP_DH on the terminal side. The correct output time of this key chord method should always be 20 bytes, as SHA-1 is run for the derivative output.

The key is checked for consistency with the KeyAgreement algorithm. For example, the type of key must match. For elliptical turn algorithms, the key must represent a valid point on the curve domain parameters. Additional tests of the strength of the component/domain parameters are specific to implementation. In the case of algorithm 7, the expected public data consists of an unsigned big endian coding of the public parameter y.
