Definition: The acronym, RSA, is related to public key infrastructure (PKI) encryption algorithm but originally stood for the last names of the co-inventors, Rivest, Shamir and Aldernam. The method was granted a patent and due to its robust nature has made electronic commerce and the verification of online identities (i.e. digital signatures) more dependable. Attribution, in other words, is made more trustworthy when using this and similar methods. A business or organization that buys or sells online must be able to rely upon the authenticity of transactions or loose competitiveness and be negligent.

Its Relevance: Encryption algorithms that produce a high degree of assurance and attribution are an e-business necessity. Information infrastructure owners must address encryption in the information security plan. Conducting business without encrypting transactions can produce a significant vulnerability and, by itself, prove negligence on the part of the business owner.
