WebApr 12, 2024 · The DES (data encryption standard) is one of the original symmetric encryption algorithms, developed by IBM in 1977. Originally, it was developed for and used by U.S. government agencies to protect sensitive, unclassified data. This encryption method was included in Transport Layer Security (TLS) versions 1.0 and 1.1. A cryptoperiod is the time span during which a specific cryptographic key is authorized for use. Common government guidelines range from 1 to 3 years for asymmetric cryptography, and 1 day to 7 days for symmetric cipher traffic keys. Factors to consider include the strength of the underlying encryption algorithm, key length, the likelihood of compromise through a security breach and the availability of mechanisms of revoki…
