Florian and Tobias would like to begin communicating using a symmetric cryptosystem, but they have no prearranged secret and are not able to meet in person to exchange keys. What algorithm can they use to securely exchange the secret key?Diffie-HellmanMD5RSAIDEABlowfishDiffie-HellmanWhich one of the following is not one of the basic requirements for a cryptographic hash function?The function must work on fixed-length input.The function must be relatively easy to compute for any input.The function must be one way.The function must be collision free.The function must work on fixed-length inputWhat standard governs the creation and validation of digital certificates for use in a public key infrastructure?X.509TLSSSLXMLX.509Howard is choosing a cryptographic algorithm for his organization, and he would like to choose an algorithm that supports the creation of digital signatures. Which one of the following algorithms would meet his requirement?BlowfishRSADiffie-HellmanAESDESRSA
