Buslink CipherShield Dual Key AES 512-bit Encrypted External Hard Drive safeguards and protects classified information when they are too important to be left in the hand of one individual. To gain access to the drive, authentication will be based on two unique Cipher Keys. Unlike its counterpart with collateral access method, this model requires both keys to be plugged in all the time while working with the drive. It is like getting a safe deposit box that takes two keys to open. This dual key encrypted hard drive is suitable for group setting where more than one individual are working on highly confidential projects. i.e. blueprints for company's next new products, top secret programs, highly confidential legal cases, sensitive customer records and financial information. USB 3.0 and eSATA interface allow user to transfer gigabytes of data quickly - up to 5 Gbps of data transfer rate.CipherShield design features a chip embedded in the access key which matches the chip on the controller board. Since CipherShield encrypts data independent of the operating system; removing the drive and connecting it directly to the SATA BUS will not defeat the encryption. Buslink CipherShield Dual Key AES 256-bit Encrypted External Hard Drive ensures high level of data integrity and security, thus supporting organization compliance efforts with federal regulations such as HIPAA (Health Insurance Portability and Accountability Act), or Sarbanes-Oxley Act. CipherShield Encrypted Drive with Bilateral Access Mode will automatically lock down its content once power is shut off. And without both access keys, the data will not be seen or accessed in the event of theft or loss of the external drive.- 2 stage cascade AES 256-bit equals to 512-bit encryption- FIPS 140-2 compliant- CipherShield Smart Insert technology with CipherKey to authenticate the drive- Real time "on-the-fly" encryption without any performance degradation- Bundled with two sets of unique Cipher Keys - a total of 4 keys.- Provides maximum protection with access requirement of two keys- Plug and play for easy installation- Conforms to HIPAA regulation regarding patient privacy, and Sarbanes-Oxley Act compliance over corporate financial and accounting practice
