Mitigation of Other Attacks The Cryptographic Module Validation Program (CMVP - www.nist.gov/cmvp ) validates cryptographic modules to FIPS 140-2 and other cryptography based standards. Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can decrypt this dat…
