A password-encrypted key (PEK) is generated from a user-supplied password or other identifyting data and then used to encrypt the user's password. The encrypted password is stored in a user record on a server. At login a would-be user's password is again used to make a key, which is then used to decrypt and compare the stored encrypted password with the would-be user's password to complete the login. The successful PEK is stored in a temporary session record and can be used to decrypt other sensitive user information previously encrypted and stored in the user record as well as to encrypt new information for storage in the user record. A public/private key system can also be used to maintain limited access for the host to certain information in the user record.

Password encryption key

A system and method for providing code signing services to software application developers or to other individuals or entities that wish to have applications digitally signed. Signing of the applications may be required in order to enable the applications to access sensitive APIs and associated resources of a computing device when the applications are executed on the computing device. In one embodiment, a method of providing code signing services will comprise at least some steps relating to registering the entities that seek access to sensitive APIs as controlled by the code signing authority, and managing the accounts of the registered entities.

Account management in a system and method for providing code signing services

A system and method for registering entities for code signing services. The entities may be software application developers or other individuals or entities that wish to have applications digitally signed. Signing of the applications may be required in order to enable the applications to access sensitive APIs and associated resources of a computing device when the applications are executed on the computing device. In one embodiment, a method of registering entities for code signing services will comprise the step of transmitting at least some account data to the registering individual or entity using an out-of-band communication system. This provides added security that the individual or entity registering for a code signing service is who that individual or entity purports to be.

System and method for registering entities for code signing services

The invention define a new protection mechanism against attacks to security enforcing operation performed by cryptographic token and smart card. It is based on an attack detector which signal to the main elaboration system a potential attack situation. The invention offer an easy solution to SIM cloning problems of telecom operators which use old and breakable cryptographic algorithms such as the COMP-128 and does not want to invest many in updating the network authentication systems with more resistant authentication cryptographic algorithms. This is requirement is typical of the telecom operator of the emerging market which use not the state of the art in technology.

Method For Detecting and Reacting Against Possible Attack to Security Enforcing Operation Performed by a Cryptographic Token or Card

An access control method controls access from an information processing apparatus which is connectable to a device requiring a first password authentication to a storage medium which requires a second password authentication. The access control method automatically generates a password based on key information read from the device, when an authentication result of a password input to the information processing apparatus and a first password read from the device is correct, and enables access to the storage medium when an authentication result of the generated password and a second password read from the storage medium is correct.

Access control method, storage apparatus and information processing apparatus

Methods for improving security in data storage devices are disclosed The methods include a synchronization method by which an encrypted password, using any known encryption algorithm, keeps changing at each transmission from host to data storage device Additionally, a security system for implementing the security method is provided
