    摘要: Aspects of a method and system for securing a network utilizing IPsec and MACsec protocols are provided. In one or more network nodes, aspects of the invention may enable conversion between Ethernet packets comprising payloads secured utilizing IPsec protocols and Ethernet packets secured utilizing MACsec protocols. For example, IPsec connections may be terminated at an ingress network node and IPsec connections may be regenerated at an egress network node. Packets secured utilizing MACsec protocols may be detected based on an Ethertype. Packets comprising payloads secured utilizing IPsec protocols may be detected based on a protocol field or a next header field. The conversion may be based on a data structure stored by and/or accessible to the network nodes. Aspects of the invention may enable securing data utilizing MACsec protocols when tunneling IPsec secured data through non-IPsec enabled nodes.

    摘要: Aspects of a method and system for determining and securing proximity information over a network are provided. In this regard, data transmitted over a network may be time-stamped upon entering and/or exiting a network node. By taking the total time to travel between two network nodes and subtracting out any latency internal to one or more intermediate nodes, the time to traverse the physical links (the propagation time) between the two network nodes may be determined. Accordingly, if the speed at which data propagates over each link of the network is known, then a distance from the source node to the destination node may be determined. Additionally, aspects of the invention may enable one or more of authentication, validation, and encryption of timing and/or proximity information transmitted over a network.

    摘要: Methods and systems for secure key generation are provided. In embodiments, during the manufacturing process, a device generates a primary seed for the device and stores the seed within the device. The device exports the device primary key to a secure manufacturer server. The secure manufacturer server generates a public/private root key for the device and requests a certificate for the public root key of the device from a certificate authority. The device, having the stored primary seed, is integrated into an end-user system. Upon occurrence of a condition, the device after integration into the end-user system generates the public/private root key in the field. The system also receives and installs the certificate for the public root key.

    摘要: Methods and systems are disclosed for generating random numbers and initial vectors. A random number generator generates one or more random numbers that are used to repetitively seed pseudo random number generators so that the pseudo random number generators generate random numbers. Thus, a single random number generator may be used to simultaneously generate several random numbers. The random numbers generated by the pseudo random number generators may be used as initial vectors in encryption engines.

    摘要: A method and system for secure and scalable key management for cryptographic processing of data is described herein. In the method, a General Purpose Cryptographic Engine (GPE) receives key material via a secure channel from a key server and stores the received Key encryption keys (KEKs) and/or plain text keys in a secure key cache. When a request is received from a host to cryptographically process a block of data, the requesting entity is authenticated using an authentication tag included in the request. The GPE retrieves a plaintext key or generate a plaintext using a KEK if the authentication is successful, cryptographically processes the data using the plaintext key and transmits the processed data. The system includes a key server that securely provides encrypted keys and/or key handles to a host and key encryption keys and/or plaintext keys to the GPE.
