Cryptographic Agility in Security Standards (A20c)
More and more standards include the requirement for cryptographic agility. Although, these are just two simple words, they have a significant impact on how systems are designed around cryptographic algorithms. The security of every system relies on cryptographic algorithms which are most of the time considered to be the strongest link in the security chain, but as with everything else, also cryptographic algorithms get weaker over time. Either due to new cryptanalytic attacks or higher computational power. To handle this risk, cryptographic agility comes into place. In this talk we will discuss the meaning and importance of it and show that the future quantum computer makes cryptographic agility already today necessary.
