Financial services — Recommendations on cryptographic algorithms and their use

ISO/TR 14742:2010 provides a list of recommended cryptographic algorithms for use within applicable financial services standards prepared by ISO/TC 68. It also provides strategic guidance on key lengths and associated parameters and usage dates.

The focus is on algorithms rather than protocols, and protocols are in general not included in ISO/TR 14742:2010.

ISO/TR 14742:2010 deals primarily with recommendations regarding algorithms and key lengths.

The categories of algorithms covered in ISO/TR 14742:2010 are:

  • block ciphers;
  • stream ciphers;
  • hash functions;
  • message authentication codes (MACs);
  • asymmetric algorithms;
    • digital signature schemes giving message recovery,
    • digital signatures with appendix,
    • asymmetric ciphers;
  • authentication mechanisms;
  • key establishment and agreement mechanisms;
  • key transport mechanisms.

ISO/TR 14742:2010 does not define any cryptographic algorithms; however, the standards to which ISO/TR 14742:2010 refers may contain necessary implementation information as well as more detailed guidance regarding choice of security parameters, security analysis, and other implementation considerations.
