Description

From the listing uploaded by “appupdater”.

The ST25DV-I2C CryptoDemo application shows how to establish a secure transfer channel over NFC, between an STM32 microcontroller and an Android smartphone. It uses the fast transfer mode (FTM) feature of the ST25DV-I2C NFC Tag. An ST25DV-I2C-DISCO board is required to run the demonstration. This demonstration establishes a secure transfer channel by using cryptography to perform mutual authentication and to encrypt the communications over NFC. This secure transfer channel is used during the demonstration to securely send and retrieve data, perform the device settings, and upload new firmware. Only the granted user may communicate with the STM32 microcontroller to perform these operations. All the communications are encrypted between the microcontroller and the Android phone in both ways, so that the user can configure the product or retrieve data securely. FEATURES : - Encryption of all NFC bidirectional communications between an Android Phone and an STM32 microcontroller - Fast communications over NFC, using ST25DV fast transfer mode - AES and ECC cryptography - Mutual authentication between the Android phone and the STM32 microcontroller - Establishment of a unique AES session key - Encryption can be used to retrieve data, set device settings or update the firmware securely

ST25DV-I2C CryptoDemo APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the ST25DV-I2C CryptoDemo APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is f9fa0b905d75015d4aacbcf38cad9915.
