A method for securing data access by containerized applications includes intercepting, by a first container executing on a first computing device and associated with a containerized application in a second container executing on the first computing device, a first Internet Protocol (IP) request from the containerized application. The first container determines that the IP request is addressed to a second computing device executing a resource that the containerized application is authorized to access. The first container encrypts a payload portion of the IP request and transmits, to the resource, a second IP request with the encrypted payload portion. The first container receives, from the resource, a response. The first container requests, from a third computing device, a cryptographic key for decrypting the response. The first container decrypts, with the cryptographic key, a payload portion of the response and transmits, to the containerized application, the decrypted payload portion of the response.

A method for distributing encrypted cryptographic data includes receiving, by a key service, from a first client device, a request for a first public key. The method includes transmitting, by the key service, to the first client device, the first public key. The method includes receiving, by the key service, from an access control management system, an encryption key encrypted with the first public key and a request from a second client device for access to the encryption key. The method includes decrypting, by the key service, the encrypted encryption key, with a private key corresponding to the first public key. The method includes encrypting, by the key service, the decrypted encryption key, with a second public key received from the second computing device. The method includes transmitting, by the key service, to the second client device, the encryption key encrypted with the second public key.

A method of restricting data access based on properties of at least one of a process and a machine executing the process includes receiving, by an access control management system, from a first computing device, information associated with an encrypted data object. The method includes requesting, by the access control management system, from a verifier, verification that a second computing device executes a process in accordance with a process attribute identified in the information associated with the encrypted data object. The method includes sending, by the access control management system, to the second computing device, the received information associated with the encrypted data object, responsive to the verification of the process attribute.

A computer-implemented method for generating probabilistically searchable messages includes obtaining, by a computing device, a textual message. The method includes extracting, by the computing device, from the textual message, a plurality of words. The method includes cryptographically hashing, by the computing device, each word of the plurality of words. The method includes mapping, by the computing device, each cryptographically hashed word to a plurality of tokens. The method includes generating, by the computing device, a set of tokens associated with the textual message, the set of tokens including each plurality of tokens associated with each cryptographically hashed word. The method includes storing, by the computing device, the set of tokens associated with the textual message in metadata associated with the textual message.

A method of providing a restricted set of application programming interfaces includes decrypting, by a secure object information reader executing on a computing device, an encrypted data object using information associated with the encrypted data object to generate a decrypted data object, the information received from an access control management system. The method includes intercepting, by a kernel driver executing on the computing device, from a process executing on the computing device, a request to access the decrypted data object. The method includes identifying, by the kernel driver, using the information associated with the encrypted data object, a usage requirement restricting a set of operations available to the process in accessing the decrypted data object. The method includes providing, by the kernel driver, to the process, a restricted set of application programming interfaces with which to interact with the decrypted data object, as permitted by the restricted set of operations.

A computer-implemented method for decrypting, by a browser application, an encrypted portion of a fragment identifier within a uniform resource identifier includes receiving, by a browser application executing on a computing device, from a user, a uniform resource identifier including a delimiter and a fragment identifier, the fragment identifier comprising an encrypted portion. The method includes requesting, by the browser application, from an access control manager, decryption information associated with the fragment identifier. The method includes receiving, by the browser application, from the access control manager, the requested decryption information. The method includes decrypting, by the browser application, the encrypted portion of the fragment identifier with the requested decryption information.

A method includes receiving, by an access control management system, from a first client device, information associated with an encrypted data object. The access control management system receives, from a second client device, a request for the information. The access control management system verifies that a user of the second client device is identified in the received information. The access control management system selects an identity provider, based on a user identifier included in the received information, the user identifier associated with the user of the second client device. The access control management system requests from the selected identity provider, authentication of the user of the second client device. The access control management system sends, to the second client device, the received information. The access control management system stores an identification of at least one of the second client device and the received request for the information.

Methods and systems for distributing cryptographic data to authenticated recipients

A method for distributing cryptographic data to trusted recipients includes receiving, by an access control management system, from a first client device, information associated with an encrypted data object, the information including an identification of a platform for generating an integrity measurement digitally signed by a root of trust. The access control management system receives, from a second client device, a request for the information associated with the encrypted data object. The access control management system verifies that the second client device includes the platform for generating the integrity measurement digitally signed by the root of trust. The access control management system determines, based on the verification of the second client device, not to authenticate the second client device. The access control management system sends, to the second client device, the received information associated with the encrypted data object, responsive to the determination.
