Import controls, which is the restriction on using certain types of cryptography within a country. Patent issues, deal with the use of cryptography tools that are patented. Search and seizure issues, on whether and under what circumstances, a person can be compelled to decrypt data files or reveal an encryption key.
Export destinations are classified by the EAR Supplement No. 1 to Part 740 into four country groups (A, B, D, E) with further subdivisions; [15] a country can belong to more than one group. For the purposes of encryption, groups B, D:1, and E:1 are important: B is a large list of countries that are subject to relaxed encryption export rules
Countries may wish to restrict import of cryptography technologies for a number of reasons: Imported cryptography may have backdoors or security holes (e.g. the FREAK vulnerability), intentional or not, which allows the country or group who created the backdoor technology, for example the National Security Agency (NSA), to spy on persons using the imported cryptography; therefore the use of ...
The export of cryptography is the transfer from one country to another of devices and technology related to cryptography.. In the early days of the Cold War, the United States and its allies developed an elaborate series of export control regulations designed to prevent a wide range of Western technology from falling into the hands of others, particularly the Eastern bloc.
Mandatory decryption is technically a weaker requirement than key disclosure, since it is possible in some cryptosystems to prove that a message has been decrypted correctly without revealing the key. For example, using RSA public-key encryption, one can verify given the message (plaintext), the encrypted message (ciphertext), and the public ...
See traffic encryption key. symmetric key - a key that is used both to encrypt and decrypt a message. Symmetric keys are typically used with a cipher and must be kept secret to maintain confidentiality. traffic encryption key (TEK)/data encryption key (DEK) - a symmetric key that is used to encrypt messages. TEKs are typically changed ...
