Abstract: A data processing system 2 operates at a plurality of exception levels ELx and supports the use of protected execution environments. A register bank 16 contains registers having associated ownership variables indicating an owning exception level. Register access control circuitry 30 is responsive to the ownership values for respective registers to control access to those registers by processing circuitry 14 in dependence upon the ownership values. Target-constrained data transfer operations and associated program instructions may be provided which are able to access data values in registers not owned by the exception level associated with the execution of those program instructions, but are limited to perform data transfers to or from memory locations within a memory 6 indicated by an architected storage pointer for the owning exception level. Target-unconstrained transfer instructions at a given exception level are not able to access register data value marked as owned by a different exception level.

Abstract: A method of asymmetrical encryption and transferring encrypted data is provided that incorporates the Lucente Stabile Atkins Cryptosystem (“LSA” algorithm). This algorithm uses certain properties of mathematical objects called “groups”. Groups are sets of elements that are equipped with an operator and have the closure, associativity, identity, and invertibility properties. The LSA algorithm uses groups to encrypt and decrypt (secret sharing) any kind of symbolic information between two or more parties.

In one example, the method includes generating a random number sequence from a true random number generator to produce secret information, storing the secret information in an on-chip secure storage, encrypting, in a device and using public key encryption, the secret information to generate an encrypted message, and transmitting the encrypted message to a third-party system.

Abstract: A computer-implemented data transmission method and system are provided. A first transformed password (PWD) is acquired from the first node, wherein the first transformed PWD is derived from an original PWD. An encrypted message is acquired from the first node, the encrypted message being encrypted with a public key of the first node. A private key of the first node is recovered according to the first transformed PWD, the private key having been encrypted with the first transformed PWD and stored in the second node in advance. The encrypted message is decrypted with the recovered private key to obtain a decrypted message for processing.

Abstract: A user state tracking and anomaly detector for multi-tenant SaaS applications operates in association with a log management solution, such as a SIEM. A given SaaS application has many user STATES, and the applications often have dependencies on one another that arise, for example, when a particular application makes a request (typically on behalf of a user) to take some action with respect to another application. The detector includes a mapper that maps the large number of user STATES to a reduced number of mapped states (e.g., “red” and “green”), and a dependency module that generates user-resource dependency graphs. Using a dependency graph, a SaaS modeler in the detector checks whether a particular dependency-based request associated with a SaaS application is valid. State and dependency information generated by the mapper and dependency module are reported back to the log management solution to facilitate improved logging and anomaly detection.

Abstract: The technology disclosed relates to non-intrusively enforcing security during federated single sign-on (SSO) authentication without modifying a trust relationship between a service provider (SP) and an identity provider (IDP). In particular, it relates to configuring the IDP to use a proxy-URL for forwarding an assertion generated when a user logs into the SP, in place of an assertion consumer service (ACS)-URL of the SP. It also relates to configuring an assertion proxy, at the proxy-URL, to use the SP's ACS-URL for forwarding the assertion to the SP. It further relates to inserting the assertion proxy in between the user's client and an ACS of the SP by forwarding the assertion to the SP's ACS-URL to establish a federated SSO authenticated session through the inserted assertion proxy.
