Monetary Authority of Singapore Technology Risk Management Guidelines 10.1: 10.1 Cryptographic Algorithm and Protocol

The FI should adopt algorithms from well-established international standards and choose algorithms and key lengths that meet its security objectives; ensure random seeds and numbers are of sufficient length and randomness where security depends on them; use only algorithms that have been rigorously tested or vetted; and monitor developments in cryptanalysis, updating algorithms or increasing key lengths so they stay resilient against evolving threats.
