Undecryptable Encryption against Network and Forensic Attack

Cryptography plays a vital role in data security. It is necessary where the integrity and confidentiality of information is needed. But use of cryptography is not sufficient for the protection of the sensitive information. There are number of cases encounter where the attacker breach the security and obtain the secret key in use or the secure information even though the strong protection against attack such as brute force, cold boot etc. has been provided. Some systems are only use for the storage purpose. Such systems are the recording devices such as CCTV, video recorders and network equipments. They just keep the information for further use in secure manner. These systems never process this stored information and even not understood it. These devices require the more protection as they either transfer the data physically or through network. Symmetric cryptography is useful when there is a huge amount of data to encrypt but provide the more access then needed. Asymmetric encryption does not provide more access but not suitable for large volume of data. So a solution is required where device is allowed to encrypt the data symmetrically, but is not able to decrypt it neither by itself nor by attacker.
