President Bill Clinton signed the Digital Millennium Copyright Act DMCA , which criminalized all production, dissemination, and use of certain cryptanalytic techniques and technology now known or later discovered ; specifically, those that could be used to circumvent DRM technological schemes.
Similar statutes have since been enacted in several countries and regions, including the implementation in the EU Copyright Directive. Similar restrictions are called for by treaties signed by World Intellectual Property Organization member-states. Niels Ferguson , a well-respected cryptography researcher, has publicly stated that he will not release some of his research into an Intel security design for fear of prosecution under the DMCA.
Dmitry Sklyarov was arrested during a visit to the US from Russia, and jailed for five months pending trial for alleged violations of the DMCA arising from work he had done in Russia, where the work was legal. In both cases, the Motion Picture Association of America sent out numerous DMCA takedown notices, and there was a massive Internet backlash  triggered by the perceived impact of such notices on fair use and free speech.
In the United Kingdom, the Regulation of Investigatory Powers Act gives UK police the powers to force suspects to decrypt files or hand over passwords that protect encryption keys. Failure to comply is an offense in its own right, punishable on conviction by a two-year jail sentence or up to five years in cases involving national security. In the United States, the federal criminal case of United States v.

Fricosu addressed whether a search warrant can compel a person to reveal an encryption passphrase or password. The FBI—Apple encryption dispute concerns the ability of courts in the United States to compel manufacturers' assistance in unlocking cell phones whose contents are cryptographically protected. As a potential counter-measure to forced disclosure some cryptographic software supports plausible deniability , where the encrypted data is indistinguishable from unused random data for example such as that of a drive which has been securely wiped.

Ibrahim A. Springer, In the last segments, we discussed methods of accomplishing data encryption through the use of protocols, which use various algorithms to transform plaintext data to ciphertext. Earlier in the wireless tutorial series of articles on wireless security, simplified expressions depicting encryption and decryption were explained:. Common to both processes is the cipher. The cipher is a key or algorithm that allows a transformation of the data.
A little history can provide a foundation for an understanding of the technology. When we encrypt data, we transform the data from a readable form that anyone can access to a form that is confidential, "secret" to only the parties that have the key to the encryption cipher, allowing them to decrypt the data. So what is a cipher? And what exactly is the difference between a cipher, a code, or an encryption algorithm?
In essence, they are all the same thing. A cipher is defined as an algorithm used for encryption and decryption. A code is a method of disguising or obscuring plaintext. An encryption algorithm incorporates a cipher and is a method transforming plaintext into a representative symbols, a code. Ciphers and codes take many forms and range from simple and relatively insecure, to extremely complex and virtually impossible to crack. Every cipher, code, or algorithm has a unique key that allows the parties to the message to encrypt and decrypt the message.
The key can be a password, or passphrase, which in turn is converted or mapped to a key. Keys are either "pre-shared," meaning that each party is in prior possession of the key or credentials needed for the exchange, or the keys can be dynamically generated, as explained in the discussion of The use of pre-shared keys requires a distribution of keys, which in itself raises issues of security.
A cipher is not a protocol, which is a collection of methods, or software, or algorithms that use the cipher as a part of the encryption or decryption process, and is an algorithm in its own right.
