Identify the digital signature schemes and MAC schemes that are supported by Cryptool. For each scheme, determine the key sizes supported by Cryptool and which key sizes are recommended by NIST. Encrypt text using two digital signature schemes, measure the execution time for key generation (if applicable), signature generation, and signature verification. Measurements should be performed multiple times and then the analysis should use the average time for comparisons. In order to obtain measurable results, you will likely need to use long messages (i.e., 5 MB or larger). If you are unable to find a suitable document, use this document from the Library: Modern Cryptography Primer: Theoretical Foundations and Practical Applications. Record results and draw conclusions. Identify the encryption algorithm used. Discuss the results of the measurements and any variations or trends observed when comparing the results from the group members. Report the results and the analysis. Be sure to include details on the measured results and details on each members computer (i.e., processor type, speed, cache size, RAM size, OS, etc.).
