Changelog

This files contains all notable changes for each version of DATA.

Versions

v0.3

Version of DATA as used in the Usenix Security'20 paper Big Numbers -- Big Troubles

Updated

  • Made cryptolib directory independent of DATA. To run:

    1. source data.sh globally
    2. source ${DATA_COMMON}/DATA_init.sh within the framework script
    3. Run analysis via framework script instead of Makefile

  • In the framework script, renamed

    • COMMON -> DATA_COMMON
    • ANALYSISDIR/leakage_models -> DATA_LEAKAGE_MODELS
    • DATA_LEAKAGE_MODELS
    • cb_run_single -> cb_prepare_algo
    • NTRACE_DIFF -> PHASE1_TRACES
    • NREPS_GEN -> PHASE2_FIXEDKEYS
    • NTRACE_GEN -> PHASE2_TRACES
    • NTRACE_SPE -> PHASE3_TRACES

  • Runtime of phase3 increased by parallel programming and optimized RDC precomputation

  • Updated Intel Pin from 3.7 to 3.11

Added

  • BoringSSL, LibreSSL
  • Support for nonce leakage:
    • PHASE3_SKIP_PHASE2: phase3 analyzes all phase1 differences rather than phase2 leaks only
    • PERSIST_ARTIFACTS: keep run artifacts for phase3 analysis (e.g. for recovering nonces)
    • Nonce recovery in ${DATA_COMMON}/dsa_nonce
  • Generic OpenSSL compilation in ${DATA_COMMON}/openssl

Removed

  • common.sh -n Result directory must be specified explicitly. This allows to run multiple instances of the same script in parallel

Known issues

  • Intel RTM (TSX): Tracing of XABORT following an indirect jump fails in Pintool. Workaround: Disable RTM/TSX in the CPU MSR, or try to switch back to Intel Pin 3.7 (in DATA/pin/Makefile).

v0.2

Added

  • Support for the graphical user interface (GUI) available here. Note that DATA v0.2 is compatible with DATA GUI v1.1, but not necessarily other versions.
  • Command to start GUI with example analysis (make gui).
  • Template directory to simplify adding new cryptolibs.
  • README.md that explains how to preload shared libraries.
  • README.md for PyCrypto.
  • Changelog to track versions and changes.

Changed

  • DATA framework now requires Python v3.5.
  • Authors are now listed in separate AUTHORS.md file.
  • Improved support for preloading shared libraries.

Fixed

  • Created leak objects with invalid RDC result under certain circumstances.

v0.1

Initial version of DATA as used in the corresponding publication.
