Cryptography Best Practices

Sign up or log in to save this to your schedule and see who's attending!

Learning objectives
  • decide if and when cryptography should be used.
  • make informed key architecture and management decisions.
  • use appropriate algorithms and parameters.
  • select an appropriate cryptographic library.
  • choose network protocols for distributed applications.

Application architects need to make informed choices to use cryptography well:

  • Alternative key architectures have their merits and drawbacks. PKIs, in particular, should be contrasted with symmetric key architectures such as Kerberos.
  • Network protocol characteristics are pivotal in ensuring distributed applications meet security requirements. Key strength choices impact on security guarantees offered, as do cryptographic algorithm modes.
  • While strong keys and wise use of cryptographic algorithms may thwart cryptanalytic attack, applications are insecure without prudent key management. In this context, key generation and key storage require particular attention.
  • The selection of crypto-libraries requires awareness of inherent library qualities and failures. Application developers are advised not to implement their own.
  • Cryptography is used innovatively in areas such as obfuscation and watermarking.
