Welcome to the JCMathLib wiki!

• Main components of JCMathLib:
  • Functional: Bignat, Integer, ECPoint and ECCurve
  • Supportive: Memory allocator and locker, Performance profiler
  • Examples & tests
• Prerequisities of used smart cards: JavaCard API, EC / RSA / memory
• Compilation, upload, dependencies
  • ant-javacard
  • GlobalPlatformPro
• Performance on real cards (table)
• Example use for ECPoint operations
• Example use for Bignat and Integer operations
• Memory management of shared objects and logical locking
  • Easy to set RAM or EEPROM placement for array
  • Allows for nuanced tradeoff between resource consumption (RAM is very limited, usually less than 3kB) and speed performance (data in RAM are written faster)
• Performance profiler
  • Prerequisities and caveats
  • Setup and execution
  • How to intepret results
