A USB token for Digital signature Certificate (DSC) is defined as a password-protected device in its physical form wherein a personal identity is established. The USB token allows the user to access a network without having to use a password. It enhances digital security as it proves the identity of the user in electronic form. Secure and strong authentication to access the network is ensured to the user. The USB token has unique in-built software that enables users to identify and open digital signatures. The terms 'USB token', 'digital signature token', 'e-token', and 'dongle' are used in a similar manner.
(i) The private key is stored in the token and cannot be passed externally in case of a cryptographic token. This leads to the formation of a digital signature on the token while signing the operation. The use of a password protected token to access the contents of the content token assures a high level of security to the users. The user has the authority to retrieve his private key from the USB token.
(ii) A USB token for Digital Signature carries fingerprint details, digital signatures or other relevant biometric data of the user which can be used as a cryptographic key.
(iii) A majority of USB tokens provide the facilities of durability and portability with security.
(iv) Most USB tokens do not require a reader and hence can be carried conveniently in hand like a key chain
(v) A USB token facilitates the ability to encrypt files or digital contracts in a secure way.
(vi) A USB port of the device is required for USB tokens to be plugged in. It could be plugged directly or with the help of an extension cable.
(vii) There is no requirement of additional drivers for USB tokens in most cases. Most of the USB tokens need lesser drivers.
(viii) With the help of plug-and-play capabilities of a USB token, the cost for training can be lessened
